So I've started my first grow. I have 14 plants from bagseed in soil in 1 gal pots. I'm using 4 4ft fluoro tubes. They're almost 4 weeks old and 8 - 12 inches high. Should I switch from 24 to 12/12 now or wait?
So they grew 3 feet in 4 weeks?? or do you mean four weeks after they actually started the flowering cycle?
....and by the way, im glad this thread was made, because i have almost the exact same set-up. 14 plants from bagseed, 44 days old, grown under four 4-foot fluro's, and are plants are looking really similar in size! We're like grow-room twins haha And I've have been debating switching or waiting just like you, so hopefully this thread gets some good advice
