Thanks everyone for your help.

In regards to the timer:
Stinky when you mentioned the $8 timer at Walmart, I don't think that will be sufficient will it? I just posted another post about timers in a different forum, but the problem I believe was the constant water to the net pots. The roots couldn't handle the constant wet. The cheap timers at Walmart seem to only go on and off a few times per day. Will that be enough?

In regards to getting a REAL light:
At one time I thought that I read on several occasions that the 430Watt San Agro was good, which is why I bought it. After coming here I read on several occasions that the light isn't any good. I'll try to research why it's not good and what I should replace it with. Perhaps since I have the ballast I can buy a bulb?

About the fertilizers:
I'll research this too thank you. Right now I wonder if I should go get some miracle grow for the ones growing in soil, but I had better do some reading.

Thanks everyone, you've helped.
