What type of timer are you using? I use a T-104 timer it can handle upto 8 ballast at once. You probably wired your ballast wrong or you have fried your timer. Easyiest thing to do if you dont know how to wire ballast is take it to a local hydro store. Get them to wire it.

You can post reply's with any specific questions and I will answer them best I can. My pictures of my room are 1 week from cutting down. Based On A 4 Light Room. Pictures are of a 8 Light Room. I start by sealing my room as best I can. From there I start by building a 8ft by 8ft box with 2x6. Then I screw 2 sheets of OSB 4x8 sheets to the bottom (sort of like a water bed box). I line the inside with polly making Rating: 5
