yeah grow bags are legit, its hard to water them though, I have another bag around the grow bag with no holes so it could retain water. its a slippery slope so be careful. too much water you get little black flies. they suck. Right now I got 6 almost ready for harvest, then 9 14 days after that, then the cage thing I have plus two plants for that round, then I put 6 girls in today in the last slot, they only stay in that last slot for like 8 days, it allows them to stretch perfectly, then they fatten up in the third stage, then the last two stages they are under optimal light to finish off. its a good system, use good dirt and make sure not to get spider mites or hermies otherwise it ruins the entire crop. I cook with most of mine any way its all personal use, I would rather eat it then smoke it sometimes especially for sleep. I have back problems so it totally helps.
