Week 18. Harvest
3y ago
Happy Harvest Day!
Rated
10/10

AMS is one of my all time favorite seedbanks! They have produced this classic strong hitter cookie and added extreme yield and frost. She really tastes like a cookie or brownie and has a very cerebral, narcotic effect. Only for experienced cannaseurs! 300 watts used, produced over 400 grams. Nuff said.
