Marijuana Grow Guide
Fellow cannabis growers, gardeners, and all other lovers of the plant life thank you for stopping by.
We would like to introduce you to our new and improved Marijuana Grow Guide, loaded with infographics!
At Amsterdam Marijuana Seeds, we have been breeding, growing cannabis, and selling cannabis seeds for over 25 years. If you would combine the years of experience of our support team, cannabis growers, and our master breeders we have over 125 years of experience. We have gathered all that knowledge and made it into this guide to help you get started with growing cannabis.
This is our labor of love and we will share it with the community for free as that is what we do in this community. Our guide can benefit the beginner as well as the more experienced growers. If you have visited our site before, you know we like to give tips, share our tricks, and more.
You can also download our full grow guide. It also contains the following extra chapters:
Life is all about learning and growing, the plants and as a person!
Happy reading to you.
It may seem like a lot to comprehend, but when you take into account that your cannabis plant wants to grow and will do its best to do so. It will give you more ease of mind.
Your role is to create the right grow space, the perfect environment, and see to its needs. If you do this right, you'll be amazed to see the plant's growth.
On this page, we have highlighted some of the basics from our grow guide so you can familiarize yourself with what it takes if you want to start growing cannabis plants. We will explain the kinds of seeds, the stages of plant growth, and how to harvest. Trust us it's a kick when you can grow your own marijuana.
This page starts with making a choice. To quote Lucifer Morningstar; "What is it that you desire?".
All factors matter when you decide which cannabis plants are best suited for you.
Types Of Cannabis & Their Effect
Originally there are three species of the genus cannabis; Cannabis Indica, Cannabis Sativa, and Cannabis Ruderalis.
Since the 60s people have started to blend these types, and while doing so creating a new type of cannabis, the Hybrid. You can read more about Hybrids seeds on our hybrid page.
Technically all autoflowers are a hybrid because they have a parent from at least two of the three species. Because of the wide variety of hybrids it's impossible to map their trades and effects individually as they are a mix.
So we will elaborate on the original three types. They all belong to the group of plants that have psychoactive properties. However, they differ in both their effects on the user and the way they look.
Cannabis Sativa grows the tallest of the three. Their buds are airy and they have thin pointed leaves. When you see the signature picture of a cannabis leaf, it is usually the Sativa dominant leaf. Since they grow the biggest, they normally also have the largest yields. The effects you can expect from consuming a Sativa dominant strain are: energizing, uplifting, increased creativity, cerebral head buzz, increased focus, promotes a general feeling of wellness, and reduced nausea.
Cannabis Indica can be recognized by their short, bushy, and stocky stature. Their leaves are fan-like and the fingers of the leaves are broad. They normally have good genetics to grow thick dense buds. Indica strains are known to have higher CBD content than Sativas.
Cannabis ruderalis is the smallest of the three, and it has narrow palmate-shaped leaves. What sets cannabis ruderalis apart is that it switches automatically from the vegetative stage to the flowering stage with age instead of needing the schedule of 12 hours of light, and 12 hours of darkness.
It also has a shorter growth period so you can have quicker and more harvests per year. This makes it popular with beginners and those without an ideal climate or grow space. Ruderalis does not have a psychoactive effect in itself.
It has been interbred with Sativa and Indica plants to take on their psychoactive traits but still remain autoflowering after crossbreeding. Even though these three species, Sativa, Indica, and Ruderalis come from distinct separate families, some growers think that Ruderalis is not even an "official" Cannabis. Still, these three can be blended and have, as most strains today are hybrid strains.
There are 3 main types of cannabis; Indica, Sativa and Ruderalis. Inidica has a more relaxing effect better suited for evening/nighttime usage. Sativa is well known for giving you a more uplifting effect, focus, and with a bit of luck creativity. Pure Ruderalis is low in THC and will not do much, it's primarily used for creating hybrids as it autoflowers and has a shorter flowering time. Hybrids are new strains that are a mix of at least two of the three original types. They can have any trait of the parent in a dominant or submissive amount.
Kinds of Seeds
A. Feminized Cannabis Seeds
The most popular are feminized seeds and for good reason, only female plants will grow and produce cannabis buds. Feminized seeds are as the name suggests specifically bred to exclude males. Many growers choose feminized, as you won't have the risk of any males stepping out of line and pollinating your precious females.
Buying feminized seeds will take the guesswork out of sexing your plant and save you a lot of time and space. It’s a terrible feeling when you spend weeks nurturing a plant and it ends up being male.
B. Regular Seeds
Regular seeds are a mix of male and female seeds. Naturally, cannabis plants produce a ratio of 50% male to female seeds. There is no way of telling if the plant will be male or female before the flowering phase. Male plants are mostly useful to breeders who like to create new hybrids.
Autoflowering feminized seeds are female seeds with the genetics of cannabis ruderalis to make the plants flower automatically with age. With auto-fem seeds, you get the benefit of feminized strains along with the benefits of ruderalis plants. Autoflowering cannabis plants are easier to grow, they have a short growth period, and they are great for stealthy growing due to their small size. Their size, however, may also be a drawback since they will produce smaller yields.
There are 3 kinds of seeds: Regular, Feminized and autoflowering. Regular seeds have male and female seeds, which, if they pollinate, will not grow weed. Feminized strains are specifically bred to be only female. Autoflowering cannabis seeds will start flowering by themselves.
The Life Cycle Of The Cannabis Plant
The cannabis plant goes through four main stages from seed until harvest time. These are:
- germination stage
- seedling stage
- vegetative stage
- flowering stage
The cannabis plant life cycle begins with high-quality seeds. The seed of the cannabis plant is dormant and needs water to bring it to life. This process is called germination and can start anywhere from 24 hours and can take up to 7 days and sometimes even more. The wet seed will then sprout its taproot and can then be placed in a growing medium. The taproot will grow down into the growing medium as the stem grows upwards and then two cotyledon leaves will grow from the stem. The cotyledon leaves will take in the sunlight allowing the roots to develop along with the first fan leaves. Now your plant is considered a seedling.
B. Seedling Stage
Specific traits define a seedling, it must have developed a stable root system and true leaves, which means it has leaves that look like the iconic marijuana leaves we can all recognize. During this stage, a seedling will grow anywhere from 4 to 8 leaves. A cannabis plant can stay in the seedling stage for a broad range of time but normally around 3 weeks. A healthy seedling will be short with dense vegetation, the leaves should look bright and green. Take good care of your plant in this stage, as any stress or defects it will experience, will take its toll. A healthy seedling will become a healthy plant!
C. Vegetative Stage
This stage is when the marijuana plant begins to take off, when hits puberty sort of speak. This is when plants grow big jagged leaves and produce much more foliage since it is now able to absorb and process much more nutrients and carbon dioxide.
The growth of the marijuana plant will mainly depend upon the rate at which its leaves can gather sunlight and undergo photosynthesis. This is why during the vegetative stage you will need to give your plant about 18 hours of light if it’s grown indoors. It’s at this stage that you can begin topping and training the marijuana plants.
D. Flowering Stage
The flowering stage is the final stage of the marijuana plant. It’s the one every grower anticipates the most, as it will show your cannabis crops coming to completion. The trichomes on the buds will let you know when the marijuana plant has reached full maturation. And when that does, you can begin the harvest.
Every stage of the marijuana plant has its own unique characteristics. Knowing the stages will allow you to give your plant the right nutrients along with an environment that will allow it to flourish.
There are 4 stages in the lifecycle of the plant; seed germination, seedling, vegetative stage, and flowering stage. For optimal growing create the right environment for every stage. The needs of the plant change with its growth.
How To Germinate Your Seeds
There are various ways for cannabis seed germination, but we recommend our customers to the paper towel method. You only need items that are custom around the kitchen. So it's cheap, easy, and successful.
For indoor growers, it's possible to skip step 5 and place your seedling directly in the main pot. Indoors are fewer threats that might hurt the seedling.
You will need the following materials:
- 2 plates
- Paper Towels
- Distilled Water (if your tap water is not drinkable)
- Good soil
- Tiny planting pots
Firstly, dampen a paper towel with distilled water and put it on a plate. Be careful not to soak the paper towel as this will prevent the seed from getting oxygen and it will ultimately rot. Carefully spread the seeds out on the paper towel and cover with another dampened paper towel and cover with the other plate. You should put the plates with the seeds in a warm, dark place. The most favorable temperature to germinate your seeds are between 72-78 degrees Fahrenheit, or 22-25 degrees Celsius.
You can open the plates once a day to check if the taproots are starting to emerge from the seed. Take notice that some seeds will sprout rather quickly while others need a week or even a bit longer to germinate. Every 3 days or so, if the paper towel starts to feel a bit dry then spray some more distilled water on top. When the taproots are 1-2cm long (not more) then it is time to transplant them to the little pots filled with soil.
Make a tiny hole in the soil, a few centimeters into the ground. You can now plant the cannabis seed with the taproot going down into the soil. You need to be sure that you plant your seed correctly or else it will not survive. Cover the hole with a little bit of soil and give it some water. Make sure the seed remains covered after the water is added.
Be sure to put your plants where there is plenty of sunlight, or use fluorescent lights. Be sure that the plants do not dry out, but also avoid over-watering. Within 3-7 days the little marijuana seedling will emerge from the soil. After that, your plant will reach a height of about 4 inches in 3-4 weeks. At this size, you can transfer the plant to a larger pot.
For seed germination, we advise the paper towel germination method because it is simple to do, and does not require any special equipment.
Soil And Containers Include Transplanting Information
Your grow medium is another important part of growing cannabis plans. We would advise using organic soil that is airy as your soil needs to drain well, and the roots can grow freely. You can even add some perlite or sponge rock to increase drainage.
Don’t use one full of nutrients as your seedling will need different nutrients than when it is an adult. Instead, add the nutrients so that you can cater to the plant's needs perfectly. Use the pH tester to ensure that the soil’s pH remains between 6-7.
Start Your Plant In A Small Pot
It is important to transplant your marijuana from the smaller plant pots to a larger pot when it's a seedling! Take into consideration that the biggest limitation for its overall development is root expansion. For your plant to reach its full potential its roots will need to be able to fully expand.
For starting growers we advise using organic soil, with no added nutrients, as you will provide these yourself. Use different amounts per growing stage of the plant. Change pot sizes accordingly because when the plant's roots can't grow the rest won't grow either.
Water And PH
Water plays a vital role in the life of your cannabis plant. High-quality water can take your plants to a higher level since it is the foundation of successful growth. Not enough water, too much water, and poor quality water will slow the growth and can cause even the death of your plant, so it is important to know what is in your water and what your plant’s water needs are.
The quality of water varies according to your source and where you live. Water contains minerals and other components that will directly affect the pH of the plant’s environment because of the nutrients it receives.
Water Your Plant Correctly
When you water your plant be sure to be thorough. Pour water evenly around the soil, making sure that the water gets to the deepest roots. If the bottom roots do not receive water, they will begin to turn upwards attempting to get to the water. Another important thing to note about watering your plants is that you need to ensure that the pot you are using has holes on the bottom so that the water can drain properly.
Your Plant’s PH Is Important
Measuring the pH of the runoff water will tell you how alkaline or acidic the plant’s environment is. A grower can purchase special tester drops or a digital pH pen. Cannabis plants like a pH between 6-7. If you can get it around a 6.5 that it is best.
How To Fix An Incorrect PH
If you find that your pH is too high or too low it can easily be corrected. There are many pH “up” and pH “down” solutions on the market that you can use to correct your pH value.
Growing with hydroponic systems
Hydroponic growing is a different ballgame, becoming more and more popular. There are many benefits like:
- you don't need any soil as water will be your growing medium
- Saves on water usage
- Utilizes space
The downside is that waterborne diseases spread quickly.
So if you can provide a safe, clean grow space, a hydroponic system is an option. But when you have just started growing and are still learning to grow cannabis, this might be a bridge too far.
Water is the giver of life. Your plant will need an increasing amount during its growth cycle. Water your plants at the right time, keep the soil moist not soaked and keep a close eye on the PH Value. Keep it between 6 and 7.
Light And Lamps
Some people prefer indoor growing, others outdoors. Either way, cannabis plants require a lot of light/sunlight for their growth. Outdoors, the sun provides the light, for indoor grows you need to mimic this as close as you can.
Which grow light you may choose, just make sure it can light up your grow space like the sun and make sure that all your plants can bathe in the light. No cutting corners! Get the right wattage, and make the height adjustable.
When creating your setup invest in good reflective foil, and cover all the walls and ceiling if you want to get the most of the light. When your plant goes into vegetative growth, leaves and branches will grow hard and fast becoming a forest. Every extra ray of light reaching your plant will give it energy for growing weed.
In the Dam, many growers say, wattage = kilo.
Meaning with three 600-watt HID lamps, combined 1800-watt, you should be able to harvest 1800 grams or 63 ounce.
Types Of Grow Lights
The two most commonly used lamps to grow indoors are:
- High-Intensity Discharge (HID)
- Light Emitting Diode (LED)
HID lamps have been around for a while, and have been seeing some great improvements making them more efficient.
LED grow lights are the latest trend in providing growing lights to indoor cannabis plants. Most growers like their effectiveness and the ability to give relatively higher yields than even the pertinent HID lights.
Your cannabis plant reacts better when the light spectrum matches its grow stage.
Let’s take an example of the vegetative stage; blue light. In this case, 460nm is the optimum spectrum. This will create strong leaves. In outdoor growth settings, cannabis plants can get blue wavelengths during the summer. When the cannabis plants get planted indoors, some lamps that can give the blue light comprise T5/T8 and Compact Fluorescent Lamps.
In the flowering phase, the light spectrum required should make the plants give rise to potent and huge buds. A red light should be used at this stage and give spectrum levels of 660nm on average.
Distance Of Lamps From Plants
Keeping lamps at the right length can greatly help to get potent plants and enhance their end yields. The emphasis is on giving sufficient light to your cannabis plants without making them prone to light burn. So make sure your grow space has enough height.
The top parts of the cannabis plant can light up to 20 cm. The heat output is under most circumstances manageable since it rarely surpasses 600W. When a small-scale grower uses a 250W lamp per square meter, the plants get sufficient light.
Invest in adjustable light fixtures (fairly easy to find) which can help in shifting the height following the plant's growth. Providing optimal lighting conditions will make all the difference when growing marijuana!
All plants need light to grow, the more light, the better. If you grow outside choose the right spot for your cannabis garden where it has the most sun hours and a minimum of shade. Indoor growers have to mimic this, use a strong lamp that has the right spread and use reflective foil, so there is a minimum amount of shade.
Temperature, Humidity, And Ventilation
Following the light and lamps are the temperature, humidity, and ventilation. Purposely done so because lights can also provide heat so you have to manage that too when growing marijuana indoors.
Cannabis plants tend to be choosy on the optimum room growth temperatures. Depending on the cannabis strains planted, the best temperature ranges at almost every phase of the cannabis life cycle need to range anywhere between 20°C and 30°C during the day.
During the night, cooler temperatures like 20°C or slightly less work incredibly well.
The right Humidity in your grow room helps to grow healthy plants, too much fluctuation will cause stress, and too high can give room for mildew to grow. So keep it steady and just right between 40 and 45%.
When growing weed indoors a breath of fresh air does wonders!
You can use it to boost or lower the humidity levels and seeing your plants waving at you makes me and them happy! Be sure your intake can provide enough airflow for the whole room.
Especially in the flowering stage as the plants are all full-grown and the space is filled with leaves and great-looking tops. A nice breeze will help your plant to grow strong leaves and provide some cooling whilst doing so.
The right balance of temperature, humidity, and fresh air gives little to no stress. This is the right environment for a healthy plant to grow!
Nutrients Needed For Each Life Phase
Like humans, cannabis plants need specific nutrients to live a healthy, fruitful life. Different nutrients help the plant with performing specific tasks like growing roots or buds. When you buy fertilizer you will see on the packaging the N-P-K ratio. These are the macronutrients that stand for nitrogen, phosphorus, and potassium. These are vital in every plant's life so that they can flourish. Most organic soil will take care of the micronutrients your plants will need.
Nitrogen is especially important during the vegetative phase of the plant’s life as it is largely responsible for a plant’s development. It aids in the production of chlorophyll and without it, the plant can’t create food from sunlight.
Phosphorus is a mobile nutrient within all plants including marijuana; it’s truly a primary nutrient for the plant. It helps with cell division, transporting amino acids throughout the plant, new tissue growth, and general health and energy.
Potassium like the other two have several jobs. It helps strengthen the plant’s immune system, it is needed for photosynthesis (how plants create food from sunlight), and potassium assists with osmoregulation. Osmoregulation is how the plant regulates the water in its cells.
Want to know a bit or two about Potassium Deficiency check out our video where Mr. Sour will tell you everything about it:
Each Life Phase Requires Different Nutrients
Marijuana plants need different amounts of each of these nutrients during each distinct life phase. Very young marijuana seedlings that have just germinated do not need extra nutrients and giving them fertilizer too soon in life can cause nutrient burn since they are so fragile. You can begin giving your plant low levels of fertilizer when 3-4 sets of true leaves (not including the cotyledons) have grown. A good starter NPK ratio is 11-40-13.
You can begin adding a bit more fertilizer when 6-7 bladed leaves have developed. When your plant is fully in its vegetative phase then it will need plenty of Nitrogen. An NPK ratio of 19-5-20 will provide enough of the right nutrients to support its robust growth during this time.
When your Cannabis plant starts the flowering stage it will again need a different fertilizer ratio. Now your plants have finished building their support scaffolding. Less leaf and stem production will take place and nitrogen stores have been built up, therefore, less Nitrogen needs to be added. Phosphorus should be increased to support the production of buds along with potassium. An NPK ratio of 15-6-30 will provide your plant with the right amount of nutrients.
During the cannabis plant’s late bloom period you should change the NPK ratio to 0-27-27 to support the plant’s bud production. At 10-14 days before harvest, you should flush your plants using a few gallons of pure water with a pH of 6.0 to 6.8.
Every stage of the cannabis plant's growth cycle needs specific nutrients to generate optimal health. Check growing schedules matching your growing medium and plant type to determine the right nutrients and amounts. An EC meter is a handy tool!
Pruning, Topping, Super-Cropping
When growing cannabis there is little we growers won’t do to ensure that we get the best yields when harvesting our crops.
Pruning means manipulating your cannabis plant by cutting, bending, or tieing, it to grow in a specific way that will give you more and better buds.
Indoors pruning should occur between 10 and 15 days before you force flowering.
If you are growing outdoors, then you should start pruning a few weeks before you expect your plant to start flowering. Tall plants can waste a lot of nutrients and energy supplying water throughout a long stem. Instead of your plant wasting so much energy growing a long flimsy stalk, it could have put more energy into growing you a big fat bud. Don’t start just whacking off leaves and branches!
The topping method is cutting off the top shoot. Let your plant grow to at least 5 nodes and cut the stem just above the second true node. The node where the cotyledons (the first two baby leaves) attach does not count as a true node. I know it seems counter-effective to cut the top off of your plant that you are eager to grow, but it will divide its energy to create multiple colas for you.
As new shoots form after the main stem has been topped, you can repeatedly top new shoots as they form. This will turn two new tops into four, and then you can turn four into eight tops. Make sure to allow at least one internode to form with a set of leaves and cut just above that each time.
Another pruning technique to increase your yields is called super cropping. Unlike topping, it does not include cutting anything off of your plant. It consists of putting your plant through some stress to increase the number of tops. It will push the lower growth higher and wider so that it will flower. Not only can this method be done on almost all plants but it can be done several times during the vegetative process. The nutrients will work twice as hard to produce higher yields in areas that would otherwise not be productive.
It's possible to manipulate your plant to grow more tops and increase yield in several ways; pruning, topping and super cropping. All of them do give the plant stress and can influence the plant's growth. So you must decide if you think it's worth the risk. Tip, you can do a few plants only and see, weigh in the end if it was worth it.
At the end of your cannabis flowering stage comes harvesting time, the moment we have all been waiting for. However, you're not yet completely there yet, there are 2 more hurdles to be taken;
- Drying or curing
Trimming is an important aspect of harvesting because it can make such a great impact on the look, potency, and smoke of the final bud.
Well-trimmed buds will excite buyers if you plan on selling some of your weed. It will sell much more quickly because it is aesthetically pleasing and shows off the beauty of the bud.
Badly trimmed bud does not give off a good first impression and brings down the entire quality of the bud. Poorly trimmed bud dilutes the overall potency of the flower as the less potent leaves are wrapping around the outside of the bud and smoking it will feel harsher.
If you are simply growing a few plants for your personal use then by all means trim, or don’t trim, to your liking. Although, if you wanted to sell some bud to a local dispensary then you should do a good job of trimming to make sure your bud looks like it belongs on the top shelf.
There are two methods to choose from when it comes to trimming cannabis. Many growers will swear on one method and another grower will convince you their method is better.
- Wet trimming
- Dry trimming
Find out what works best for you!
For both methods, you will practically need the same equipment: good quality pruning scissors, larger pruning shears, rubbing alcohol (to clean the sticky residue off your scissors), rubber gloves, a clean work area, and containers to organize the trimmed buds, untrimmed buds, and leaves or “trim”.
To begin your wet trim you will use your large shears to cut the branches off the cannabis plant. You can hang your freshly cut buds on a line so they don’t get squashed in the container near your workstation.
You want to first remove the fan leaves starting at the base. The fan leaves will just be normal leaves without trichomes on them. You can save these and the trimmings to make hashish with.
After the fan leaves are removed it’s time to get up close and personal and start trimming the smaller leaves with the trichomes on them with your smaller scissors. You will cut all around the bud to reveal the cannabis nugget, pay close attention to how you are sculpting it as this will be the look of your final product.
You should do this over a baking tray or bowl to catch the small leaves and extra trim so that you can save them for making edibles, topicals, or hash.
Now that the final product is revealed you can cut the bud off the stalk and let it dry on a mesh rack or leave it on the branch and hang it to dry.
Your drying environment should be dark and have some airflow like from a fan. Avoid direct wind to your buds. You can put a dehumidifier in the room for a nice touch. Keep an eye on your harvest every day. After about 5 to 7 days your harvest will be dry enough for curing.
The process of dry trimming begins the same as the wet trimming, so you will cut down the branches and remove the fan leaves. Now you will hang up the branches in a drying space that is dry, dark, and cool with nice airflow.
Don’t overcrowd this area as that may cause mold or mildew to grow. After 5 to 7 days you can check to see if they are ready for more trimming by bending the stalk. If the stalk snaps then they are ready for the next step.
The leaves have dried and created a shell around the nugget. You should begin trimming the leaves off over a baking tray to sculpt the bud into its final product.
The trichomes will be delicate so be careful with every cut. These buds can now be put into a jar for curing.
Now you have a great supply of beautiful nuggets and a stash of trim leftovers to make into edibles or tinctures.
Drying or curing
By the time you are ready to harvest your bud, you have already gone through an incredible journey taking care of your cannabis plant.
You have raised them well, but you are not done yet. You are the last step away from lighting up and reaping the rewards of your crop.
How To Dry Your Buds
Although removing leaves and stems during harvest speeds up the drying process, moisture content becomes uneven. Quick-drying methods also trap chlorophylls, starches, and nitrates inside the plant tissue which affects the burn and taste.
Drying marijuana slowly is the way to go. This way the moisture evaporates evenly into the air and you get evenly drying buds with minimal THC decomposition. As the pigments break down taste and aroma improve. Slow drying allows enough time for the pigments to deteriorate.
One of the best ways to allow this process to take place is by hanging the entire plant upside down to dry. Don’t allow the plants to touch each other as this increases the chance of mold forming.
The ideal situation to dry your plants is to keep a steady temperature of 65-75 degrees Fahrenheit (18-24 degrees Celsius), and avoid putting fans directly on the plant as that will cause it to dry unevenly. The humidity should be kept between 45% and 55%.
Your drying room should be quite dark as direct sunlight degrades the THC. The drying time of your bud will be dependent on temperature, humidity, and bud density.
By the end of a week, you should be able to start curing your buds, but really big and dense buds might take a few days longer. You can tell if your buds are ready to be cured by squeezing the buds to check their moisture content.
The bud should be dry but not brittle. Also, check the stem; bend it, if it breaks (not just bends) then it’s ready for curing.
Curing is the way to go to fully enjoy the fruits of your labor. You don’t want mold to stand a chance of ruining your crop, and of course, you want the maximum flavor and potency you can achieve.
Harvesting and curing are the last steps to be taken before you can finally sit back and smoke, don't be hasty now, these steps do influence the end product. Whatever method of trimming and curing you choose do it with love, care and patience, and your buds will be AAAMS- Grade!
