No pre flowers, been 2 months since I popped the seeds. I haven't seen a single preflower on anything and I started the room 4 months ago, all the rest started off 4 clones, and they made lots of babies. Can't make babies off em if I don't have a sex, I could flower them and get an ounce or two each, but I want to have some for budding in 6 weeks indoor, some for cloning, and one to do outdoor. So at least 4 out of 20. Lol. Either way 2 gal pots won't last much longer and it would be dumb dumb to put 20 in 10 gal pots or bigger without knowing what I got. Anyway since I haven't heard any tricks to getting them to show sex for a couple days/ pre flower, and it sounds like everyone says flipping 12 12 on for long enough to see something is a bad idea guess I'll I'll clone em and experiment on my clones to correlate sex. I'll number each plant and make a map on my rapid rooter plugs dome/ and transfer numbers onto cups. Probably gonna take me a good 3 weeks like this though to do what I want. May as well top em all, they're stretching too much and need to fill out. I appreciate everyone on here's time in helping me with my issues. Thank you
