jackberry When you think of 420 XTRM, you think of stability, amazing yields, and excellent quality. The buds are covered with nice sticky resin. After rolling your 420 weed into a perfect joint, just light it up and experience the sensation of all the amazing flavors. Sounds pretty amazing, doesn’t it? Check out Amsterdam Marijuana Seeds’ newest 420 strain, which is part of the haze family.




420 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. 420 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 420 strain absorbs nutrients from the soil very fast, so make sure to provide it with our marijuana fertilizer.




As a Sativa hybrid, this AMS strain has a very high THC level. You can grow this plant indoor 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 Top420Shop is in the early fall.




Your creativity will be sparkling after smoking our latest strain 420 XTRM. And besides that, this strain will boost your energy day after day. Order your precious 420 marijuana online at top420shop (420) and enjoy growing a stable and beautiful strain. You’ll be rewarded with the strong and long-lasting high of your own 420 weeds.
