I had a micro-grow wayyyy back in the day. Used a 70watt MH and a 70watt HPS. I only used the commercial 'general lighting' bulbs (obviously, no grow bulbs in 70w ) and I must say that that system worked better than the 150watt HPS (also with generic, commercial lighting HPS bulb) that replaced it.

Don't know if it was the spectrum, or the fact that I could get my trained plants an inch closer or what.

I almost bought a Sun System Super Spectrum hood for 2x250watt ballasts but decided to try a Lumatek electronic.
FatSean Reviewed by FatSean on . Dual Vs. Single spectrum? Okay so i have been away for a while an have to change my op plans. So i am wondering has anyone use them dual spectrum lights." Runs a HPS light and a MH in the same hood" Cause i am not sure if i should go with a 800w dual spec., Or should i just go with like A 6oow Hps light and get a 600w MH conversion bulb? I am just courious if the Dual one is a better way to go. As more watts and all. But the other way its getting 200 more watts in each area.? Not to sure what to do/go with so Rating: 5
