12/12 indoor, when to flower

I have a few seedlings in a PC stealth nursery. I also have a closet with a 400w HPS.

Question is, at what point are the seedlings ready for the flower room? Is it size? Number of nodes? A set time?

whenever u want

it depends on the size of your grow room ushually i start mine for flowering after 4-5 weeks

its a combination of 1) how big will the ladies get, and 2) how much space do u have.

keep in mind the ladies will stretch after u flip the switch and plan accordingly. indicas and slow vegging/growing ladies need more veg time to really get a decent yield

The nursery has about 18"-24". The main reason I ask is because previously, I had some seedlings fry in the flower room. I'm assuming that more mature plants can deal with higher temps easier, though I could be wrong.

The idea is just to get them to cycle fast and often with 12/12, with one tall cola. Not too fussed about each yield. Well, unless it's completely crap. From what I gather, 12/12 party cup grows get about 1/3 ounce-ish, which is fine for me.

They're doing OK, about 4" now, growing their 3rd nodes. Which is further than my previous efforts. I guess I'll wait until there's no room in the nursery, which will be when they're about 4 weeks.

Thanks for the tips guys.
