Just use some 75 watt fluro tubes and move them around so that the light hits different parts of your plants.....moving the tubes as you see fit.

I once built a grow cab for a medpatient with a 250w HPS and 2 75watt Fluros. Yielded 3 1/2 OZs from one plant without any special training.

I use HPS along with fluro tubes to grow my fruit/vegtables. Works like a charm.
thecurious1 Reviewed by thecurious1 on . Add some CFL to 150W HPS cab? I just built a 150 watt HPS cabinet for doing a sea of green grow. I was wondering if it would be worth while to throw in a couple of cool white CFL bulbs too to get some blue spectrum in there? Just a thought, I don't know if it's really worth while, but it would be easy to do. Rating: 5
