When To start Flowering??

Okay My plants sprouted on the 28th of Jan put them in dirt on the 1st of Feb. They are looking very great. I just started them on Nute's Fox Farm Big Bloom and Fox Farm Grow Big this week and wow they blew up just got bushy and tall lot's of more leafs coming in. I'm only using a 150HPS light and both (2) of them can bearly fit under it. when can I start flowing them They're on 24/0 lighting when Can I start on 12/12? I don't care about a big yeld. Any tips :thumbsup:

IMO if your plants have reached a height of about 1 to 1.5 feet or 5 or 6 nodes high and ur limited on space go ahead an switch to 12/12 to force flower

Sounds like your gonna run out of space, they will double in size (at least) during flowering. Switch 'em now and good luck:thumbsup:
