lighting for vegetation

sswaldo · Mar 22, 2014

I got 5 plants im going to start. was wondering if anyone has any suggestions for how long the lights should be on for? was going to do 13/11 or 14/10 (13 and 14 being on). got a 750 watt metal halide light going in a 4x4x6.5 tent.

24/0, 20/4 & 18/6 seem to be the most common veg light cycles.

At 13/11 you're cutting things pretty close...

If you plan on flowering in the same tent I would do 14/10 until they preflower and show sex. Then put the females right on 12/12.

13/11 will flower most plants, some will even flower on 14/10. It does depend on the strain though.

For veg I run my lights 24/0.
