....Can you put a smaller watt bulb in a 400hps???????? If not I have 12-23 watt veg cfls, 8-40 watt flower cfl's, and one true 65 watt flower cfl. I can use those being they are not in use. Need someone to scetch out something, I have a hard time following when I read, if a diagram or pic is involved its easier, attention span doesnt stay very long being bipolar. And the inline duct fan from lowes is what I have to work with, I have a 6 inch and an 8 inch, I suppose I can get computer fans, just dont realy know how to make them work on AC voltage
The only way you can put a smaller wattage bulb in the ballast is if the ballast is dimmable...Otherwise, no you can't. But all those cfl's will work just fine...And, if your using cfl's, then as far as the fans go, all you'll need is a couple computer fans...
I hear ya with the bipolar. Me to man. Drawing is not my strength...
