So I bought some black trash bags-- .95 mil, and they're completely see through in the sun. I went back out and bought 2 mil., twice as thick, and you can still see through them in the sunlight! I need to see if doubling the bags works. I've got s little time as I'm still waiting on my nutes to arrive. I'm looking forward to inducing flowering and finding out how many females there are.
I also bought some wire framing that I'm going to put around the plant's, like a box. I'm thinking about cutting up the bags, combining them and double or triple layering them. Then using the combined bags like on large bag, or tarp, around the plants in the wire box. It's going to look pretty red neck, but I think it'll work. As long as they're in complete darkness for 12. I'll be happy. I know it's a commitment, but I'm willing and able.
Has anyone used this method to induce flowering? How long when I start this will it take for sex to show? Thanks.
