I keep wondering whats so cool about those tubes.

Those things will burn ya!

Personally, I employed the use of the screen cover on our big screen TV. All I had to do was suspend it tween the light and the plants...using monofilament line...it looks to just be hanging in mid-air.

The temp on the light side is a full 60+ °F than the temp on the plant side.
slowthestone Reviewed by slowthestone on . Ballast question Hi all I got a 400W MH lamp with a ballast. Also have a 600W HPS for flowering, also with a ballast. Problem is, I'm vegging with the 400W but the weather is just too hot. I can manage temps with difficulty. If the weather doesnt change soon, I will have major problems with flowering once I switch to 600HPS. What I want to do is to get a 400W HPS bulb for flowering, I'll use the 600W exclusively in winter. Question is, can a 400W HPS bulb be safely connected to the ballast of a 400W Rating: 5
