this is my first time and i cant figure out when to switch to 12-12... They have been in the soul 13 days. I am growing under a 1000w HPS light, on an 18-6 right now. please let me know if i can switch.

To be honest it just depends on personal preference. If you have the room to keep growing, keep growing. They say that a plant doubles in size during flower. So if you want your final product to be double that, make the switch.

I'm not sure I'd doubt the guy. I've grown some not quite as big....maybe 2/3ds the size and I was under (2) 400s. He is under (1) 1000. Then again...I grow hydro.

I've come to the conclusion that his plants are clones. Flower when YOU want to & remember they will double in size so if you started 12/12 now they would probably be around 3' tall when finished.

Listen to Dfunk. If they're clones you can flower anytime. If they are from beans I wouldn't go to 12/12 before preflowers show. In some cases they even triple in size too so consider your ceiling height/light fixture arrangement if you can't LST

they were in rockwool cubes. I got them as clones, they were about 3" tall each. I will watch for preflowers (im guessing little hairs...). Thanks.

I just saw that there is a second page of responses... they are from clones and I will wait a while before i go to 12/12 since they will only double. I have about 3 more feet i can take the light up and i have about 3 feet from the lights to the canopy. Since they are now about 12-15" tall i will wait till they are an average of 18" so i get a final height of 36" and still have 3' to keep the light away from the plants. Does that sound like a reasonable plan?
