    LED Flowering at 12/12 or 20/4

    Howdy Folks, As the title suggests i have a bit of a dilemma, I have always used 12/12 for flowering time but with my new Viparspectra V900 it suggests in the book that came with it to use 20/4 for flower, not sure why this would be, any thoughts on this? Cheers Z

    Is this a female?

    Tips for changing to the 12/12 lighting stage

    Hello all, It's been 3 months since my plant popped its head out of the soil. In all this time, it still is not showing its sex. I only see the stipules. Anyway, I figure I'll put this thing into a 12/12 light cycle in the next few days, and find out its sex that way. Besides, if I don't, it...

    How dark so no hermies

    So how dark must my room be so I don't have problems. I'm growing femanized seeds, soil, Humboldt nutrients, greenhouse grow and have to move to dark room, can I just cover or is it worth the time to move to complete dark room? My plants are tall already.

    Will 12/12 - 12/12 - 16/8 Light Schedule Mess Up The Plant?

    Trying to figure a way to boost production for a tiny plant. It is a C-99 Grapefruit that I put into flower at a very small size. It is severely tied down in what I'd describe as a centipede shape of tie down and bending to circle around the rim of the pot. Since it was small...it will only...
