I have a grow light from a hydro store I got it cheap, I'm looking to upgrade the ballast and perhaps the bulbs I wanna go with these bulbs from the bay,only cuz of the price. 4 for the price of 1-2 depending what LFS u go to $35.00 shipped
Thing is what's a good ballast to get that will run 4 T5s 54W each. Nothing that will be the price of a whole new light. I have a 70g custom so its 36x24x18-19.
