1. Don’t Tell Anyone

Don't tell anyone

This first mistake may seem like common sense but it's actually one of the most frequent ways that growers get caught or robbed. Don't tell anyone that you're growing marijuana. It sounds simple, but people commonly over-share when they talk about growing their cannabis plants. Word spreads and all of a sudden, everyone knows about your grow.

This may seem pretty innocent. You tell your friend because you are proud of your work and you want to share. You may even want to bask in the light of recognition of a job well done. Resist the urge to do so.

Consider the possible consequences of telling people about your crop. You could bring unwanted attention from thieves, local authorities, or just your neighbors. We all know that there is nothing wrong with growing weed, but some people don’t feel that way. I have a friend who used to say, “No one needs to know your business.” In this case it is a good idea.

Remember, the best way to keep a secret is to tell no one. When you are growing marijuana, the best way to avoid any problems or complications is to keep it a secret.

2. Pick the Right Strain

Choose the right strain

If you wanted to fly overseas, would you take a bicycle? If you wanted to play guitar, would you take drum lessons? Would you use a hammer to clean your windows? I hope the answer to all of these questions is, “No.”

What is the point of all of this? Choose the right strain of marijuana for what you want, the climate of your grow space and avoid seeds with bad genetics. You don’t want to end up with a cannabis plant that is stunted because it is not suited to your climate. You don’t want to grow an Indica if you were trying to grow a Sativa.

But how do you know what to do? After all, this may be your first time ever-growing. Well, read on to find out. Check out our post on the most popular cannabis strains.

3. Not Doing Your Research


Let’s say you know someone who smokes Wedding Cake. You want to try growing it. Where do you start? You have to do the research. The problem is that there are so many articles on the internet, you don’t know what’s good or bad. Maybe you are an absolute beginner and don’t even know where to start at all.

It can be difficult. But take heart: it’s not impossible. You just have to start looking. Maybe get a book on cultivating cannabis. Maybe read an article on grow lights and the best ones for growing marijuana.

So what am I getting at here? There is a wealth of information available on growing marijuana. A ton of it can be found on the internet. Just open your favorite search engine (maybe use the private browser tab if you want to follow step 1) and start searching. Maybe look up some blog articles.

I know a great place to research growing marijuana: our blog. Check it out and start reading the articles. They are written to share as much knowledge as we can gather together in one place. Research who you are buying from. It’s important to make sure you are buying from a reputable source, like AMS.

4. You Didn’t Check the Gender of Your Seeds

Gender Seeds

Check the gender of your marijuana seed. But how, you ask. Well, this is a bit tougher than just going to the store and looking at the seed. It’s not like the gender is printed on the seed.

Instead, you have to find yourself a reputable seed vendor and make sure that the seeds are feminized. Feminized seeds are seeds that only carry female genes. This way they should only produce female plants.

Check out our post on feminized marijuana seeds.

5. You Used Bag Seeds

You don’t want to use bag seeds. Those are the marijuana seeds that you find in the bottom of your bag of weed, or in the buds that you bought. Unfortunately, you just can’t know what you are dealing with when you use bag seeds. If you don’t know what type of cannabis seeds you are dealing with; you will not be able to produce predictable (and good) results.

Oftentimes these seeds are duds. They can be damaged, runts, hermaphroditic, or male seeds. All of these conditions are not good for growing marijuana. The plants which produce buds are females. If you have male seeds mixed in with females, you will need to remove them before they are able to pollinate the female plants.

Another thing you don’t want to have to worry about is the amount and time and money you spent working with those potentially bad cannabis seeds. Let’s say you have two people growing their favorite weed. One is growing from bag seeds and the other is growing from seeds they purchased from a reputable source. Maybe you will get a decent crop. But chances are you are going to have issues.

6. You Used the Wrong Fertilizer

Use the right fertilizer

Remember that time you went an entire year eating only cookies? No? What about the time you only ate cake for a year; do you remember that? No? Well, I hope you don’t.  I hope you don’t remember it because you didn’t do either of those things.

Fertilizer is the minerals and vitamins your cannabis needs in order to grow and be healthy. Much like the examples I gave above, you have to use fertilizer correctly. The wrong type of fertilizer can be bad for your cannabis plant. You want a fertilizer developed especially for use with marijuana.

You need nutrients in the soil. You want to make sure you have the right type. The same fertilizer that is good for tomatoes or basil may not be the best fertilizer for marijuana. It pays off to do some research. You can also check out our blog post on fertilizer and marijuana.

7. Nutrient Burn

Nutrient burn happens to marijuana plants when you use too much fertilizer. It often happens when you fertilize every time you water. So you don’t want to burn your plants. So when do you fertilize to avoid this?

If you used organic soil, you shouldn’t need to fertilize until about a week or two after the plants have started to sprout. When you do, use a combination of Nitrogen, Phosphorus, and Potassium at a ratio of (2:1:2). Around the 6th -8th week, consider Switching to a ratio of 10:5:7. Then do a 1:1:1 late in the growth.

It's also a good idea to leach the plants with lots of pure water every few weeks. Luckily if you do over-fertilize then you can still save your plant, although, the "nutrient burn" on the leaves will remain there for the rest of the plant's life.


8. You Weren’t Prepared

You did your research. You found which strain you wanted to buy. You bought your seeds. You are ready to go. Right? Wrong. You need to prepare everything else involved with growing your marijuana plants before you start to grow.

Are you growing indoors or outdoors? Each one of those grow plans requires a different process. You may not be worried about rabbits with your indoor grow, but insects can be a problem. What about if you are outside? You may not need to grow lights, but you will need something to keep random animals away from your plants.

You want to have everything that you need set up ahead of time. You do not want to find that you desperately need something for your cannabis plants, and you don’t have it. The old saying applies here: An ounce of prevention is worth a pound of cure. Make sure you have everything you need before you start.

Expert growers plan well in advance before the growing season ensuring that their crop will have the best chances of being prosperous. Being prepared means doing your research of what supplies you will need and acquiring them. You should also be aware of what your cannabis plant will need including, water, nutrients, light, pest prevention, and CO2.


We have gone over some rookie mistakes in order to make sure that you have the best chance of getting the most from your marijuana plant. Stay clear of making these mistakes and you will give your crop a really good chance of being prosperous.
