My space is around 4 foot x 6 foot & 8 foot high,i figure thats pretty good size to grow a descent size pants.I'm hoping i can get them around 3 foot high & put them into flowering then.I appreciate the info shake,i wish i'd talk to you before i started lol,i could have used my grow space in a better way than i did.As you said live & learn lol!I think they'll do ok around that height 2 1/2 to 3 foot in veggie then i'll cut light for 3 days on them,then put them on a 12-12 cycle & see the out come.I'll take some pictures every couple weeks and post them & maybe you & some others can give me some more good advice!Also on topping them i have plucked tops onetime should i do them like one-more time to get more runners on them?Thx for the info!
