Product info

When you think of AMS XTRM, you think of stability, amazing yields and excellent quality. The buds are covered with nice sticky resin. After rolling your AMS 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 AMS strain, which is part of the haze family. 

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 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
