Wow dude... That is perfect... I was trying to think of a little setup that I could build, and maybe slide the plants into a black-box at night, but thats even better. I could just slide the roof instead of the plants

SOG ftw

This is what I would use. Works going downhill as well. I've seen tarps 53' long and I'm pretty sure they'd make you a bigger one if you asked. Only 8' wide as built but it should scale up.

Hi. I am starting to grow some sativa dominant plans in my friends greenhouse. I would like to start them flower in the begining of August. I am thinking to cover them to full dark for 3 or 4 days to start them flower. Feed them with pk 13-14 for support.
Does anybody know whats gonna happen if i uncovered them and the sunlight is still more than 14 hours in a day?
Thanks.

I don't know from personal experience, but I've read that some strains can sense that the nights are getting longer each day, and so they stay in flower, even though removing the blackout mechanism means that the plants are exposed to longer days.



I'm at the point where I have two plants in flower now, and I'm wondering when I can stop covering them, and just let the natural daylight take over.



Thankfully, I can go on black-boxing the plants as long as I need to, but I too wonder whether it is necessary.

Ok, the OP asked about forced flower not greenhouses.

I have done my last three grows this way. I start seed in cups then when 10-12 inches I transplant to 1 gallon pots. The 1 gallon pots, once they have at least 5-6 nodes then are moved for a 12/12 cycle into my bathroom with towels covering the window. After 6-8 days I can see what sex the plants are going to be. You can re-veg but I never do.

After that your plants follow the flowering cycle that your seed seller told you or you do the waiting game like everybody else.

Oh, I live in CA and grow outside. No giant electric bills that way. I feel sorry for indoor growers.
