Hello! Can somebody please explain how to hook up the MH bulb I have to a ballast? What exactly do I need to do this and how do I go about doing this?
Nevermind the question anymore. Take a look at this for me please. http://desmoines.craigslist.org/mat/1060591339.html Do you think one of those would be good enough for ten small plants?
You want around 100w per plant... but with them being small, it should work out, but i'd still get a little more light if possible.
You don't screw the bulb into the ballast, you screw it into a mogul socket that is wired to the ballast. One 400w HID will get 10 plants started but won't be adequate to grow them all out. If you are talking about starting with 10 sprouts to end up with about 5 females, then yeah it would be adequate. However, that link is to a MH, which is not good spectrum for flowering.
