Super Stable

While Xtrm isn’t something we would recommend for absolute beginner growers, it is a pretty easy strain to cultivate – so, good news, you don’t have to be an expert! Being a sativa-dominant hybrid, you can expect lengthy leaves and fat buds smothered in a lovely, frosty layer of resin. Your harvest will come full circle in around ten weeks, and it will be worth it so don’t get impatient and harvest too early! How worth it, you ask? Well, if growing inside, your yield from these seeds will be about 400 grams, and if you were to grow outside then it will almost double! What are you waiting for?

AMS XTRM seeds also produce strains that won’t break your heart should the weather conditions become adverse. Her stability enables her to withstand strong winds, strong sunlight, and of course, optimum growth-inhibiting factors such as caterpillars and molds. We like seeing her as the beauty that living organisms cannot call home. 

Our perfect love for you

AMS Xtrm is made by us, for you. Not to toot our own horn or anything, but we definitely deserve a pat on the back for this one. This strain boasts fantastic yields that are sure to be top quality every single harvest.

AMS XTRM seeds give plants up to 750gms per square meter, and this is an assurance that our creation is typically what you cannot afford to miss in your pot farm. We surely feel that this is like our agape love for you if at all enormous yields are anything to go by. 

Perfect For Medicinal And Recreational Use

Despite the fact that this strain is great for getting the creative juices flowing, it is also amazing at relieving pain and other symptoms of a variety of ailments. Xtrm is super relaxing, and so is ideal for treating pain related to physical illnesses as well as pain that isn’t so physical. That’s right, Xtrm has the potential to help with anxiety, ADHD, ADD and more because it is incredibly calming. It has also been said to help aid those who suffer from insomnia and other sleep-related problems.

Being 80% Sativa, we can’t be wrong to say that this is your ultimate go-to if you would like to start your day high, focused, and with a sense of mental clarity. If mood swings describe your attitude, especially during the morning hours, then we can also agree that you will be on point if you take your favorite hit of this Sativa-dominated pot.

Stable And Moderate To Grow

AMS XTRM is one of the most stable strains to grow, so if you are looking for your first strain, this is the one. You will be able to breed this feminized strain without any problems. It has long-fingered leaves and the dense, sweet bud formations appear light green due to the frosty resin coating. AMS seed needs 9 to 11 weeks before you can harvest. Don’t harvest too soon, because the desired sticky resin will cover the buds in the last 3 weeks. 

Tip: while growing, keep in mind that the AMS strain absorbs nutrients from the soil very fast, so make sure to provide it with our marijuana fertilizer. 

If you can, also be sure to supplement the AMS XTRM seeds after germination with coffee grounds before the application of the artificial marijuana fertilizer. This will undeniably help you in ensuring that your ganja plant will always have sufficient nutrients should it grapple with the artificial fertilizer faster than anticipated.  

Powerful And Potent

Just as this strain probably isn’t for beginner growers, it isn’t really for beginner smokers either. In fact, Xtrm packs a powerful punch with its THC level of 23%! Don’t worry though, this isn’t the kind of weed that will have you glued to the couch. Instead, Xtrm will induce masses of creativity and euphoria.

And, no! It would be best if you don’t get discouraged at this point if you are an absolute beginner. We also have a plentitude of marijuana strains with THC levels averaging between 5 and 15%. For instance, think of our equally fantastic Super Skunk Auto

An Exotic Taste

There are some kinds of weed that aren’t exactly pleasant to smoke, but luckily this isn’t one of them. Xtrm tastes exotic, with spicy notes and citrus flavors that’ll leave you wanting more. It really is a beautiful smoke, so why not try your hand at growing some today?

Grow Specifications AMS Weeds

As a Sativa hybrid, this AMS strain has a very high THC level. You can grow this plant indoors and outdoor. If you prefer indoor growing, the harvest can add up to 400 grams per square meter. Outdoors it almost doubles 750 grams of buds on the same surface. The best period to harvest AMS weeds is in the early fall.

We mostly advise our growers to order their weed seeds well in advance to avoid uncertainties associated with delayed shipping times or in case of rare occurrences such as damaged seeds during shipping. You need to sort the time factor in such a way that should there be any inconvenience and replacements have to get done, then that should follow right before summer.
