6. Northern Lights Xtrm ® Feminized

The Northern Lights Extreme feminized strain from AMS packs a punch of 20-30% THC level. One of the reviews on the AMS website says, 10 of 10 sprouted within 24 hrs by soaking in the water on my seed mat. About 9 days old and there growing very healthy and fast in 3-gallon pots with coco/potting soil” 

This strain has a moderate growing difficulty and with the right procedure, then anyone can succeed with growing her. Up to 550gms per square meter indoor yields and up to 675gms per square meter of outdoor yields, this is your weed to keep your mind boggled. Your no-ordinary 70% Indica and 30% Sativa. 


Bumper yields best explain the yielding capabilities of the Happy Haze feminized strain. This is one of the few strains that yield well over the 1000 mark, where when grown outdoors, she yields 1200gms/sqm, and in the case of those who prefer indoor cultivation, they get as much as 700gms/sqm. 

A 75% Sativa and 25% Indica, Happy Haze feminized best suits those who prefer taking weed for daytime. Depending on the phenotypes, this strain has potency levels ranging between the higher side of the 20-30% THC range. 

As the name implies, the effects are mostly happy. It is worth mentioning that while these beans may sprout fast, the duration from the seedling stage to flowering is relatively long.

The O.G. Kush XTRM feminized strain from AMS is one of the lowest-yielding strains. The indoor yields are up to 225gms per square meter, with the outdoor yields going up to 300gms per square meter. This is an Indica hybrid with a dominance of 70% and 30% Sativa. 

The THC levels are up to 30%, with her mostly providing euphoric effects. The critical reason why I included this specific strain in this top 10 list despite the low yields is the fact that her high is extremely energizing and functions all the day round.
