mh or hps

Hi all, Just was wondering, i'm gonna go 12 -12 tomorrow , should i put the hps bulb in or give them another week under mh?

I would keep it under the MH for a week or two more

Bro from what I've read if you can swing both @ the same time that would be optimal. And surrounding the corners with florescent light would be overkill even though both HPS and MH together is overkill.

I agree, 1-2 more weeks seems to make a difference unless space is an issue.

what is your intended goal? if you want yield use your HPS if you want quality use your MH. or as already said use em both for best of both worlds potency & yield

If you got a nice big (125w [real]) CFL in daylight color, toss that in w/ the HPS. Gets the color it wants for both the flowering parts, and the vegging branches growing to support them. Remember, adding a light always adds light, even if "you" dont see it too. Its why ppl stack on the CFL bulbs... combined lumens.
