lighting question..

I have 2 400 watt mh fixtures... I bought a hps conversion bulb for one of the fixtures.. is it ok to flower with a hps and mh bulb at the same time?

Yea, but why not just use two HPS bulbs for flowering??

sure as long as you have the space and the air circulation. Why not go perpetual and just use one for veg or do you already have that covered?

I would, specially if the HPS isn't a dual spec lamp. YOu get the best of both worlds that way. No big stretch when you start flowering either.

I read somewhere that you could use either all the way through....
The cost of the conversion bulb limited me to one...
I figured it would be good to use both.
I will start a perpetual grow after this practice run
Thanks everyone!
