i did fems from G13 labs and a single fem freebie from homegrown fantaseeds i got from the tude. if you want fems, i'd go with g13 labs, both were really good, strong piney green pinesol smell. the g13-labs version is still available while hgf is not. i know nirvana uses NL in its Aurora indica and in its chrystal, both are better than their own version of NL its visible how much better they are even without smoking them, the smells, the resin and the flower times are shorter if you grow the AI and chrystal, the strength and high you get from nirvana lingers in these hybrids and by that i mean, both these strains have strong body high smoking enough will put your brain in a stupor. (chrystal leans sativa while Aurora indica is almost entirely indica.)
