Well title says it all. I vegged for 1 1/2 weeks at 24/0 then moved to 12/12 for about 3 weeks then saw it was male. It was about 7 inches tall. Can I make qwiso hash out of it? How would it be potent if no trichomes have even formed yet?
You'd have to be really desperate to make hash from a male. It's just not worth it. And, as mentioned, that's not enough material, male or female. Sorry your grow was a waste, but at least you have the experience. Good luck next time.
You already did something with it. You learned the basics of cannabis cultivation, which is more than most people learn about this plant. Be proud.
