Hello THC nation,

I have a 400HP lying around and found a used 32''x32'' grow tent. What are your opinions on using this light from seed?
I have a dimmable ballast 50%, 75%, 100%. Can this light be TOO MUCH?

If so I will run CFL's until flower, but I already have all the equipment right now to try the 400.

Looking forward to hearing your experiences,

Rakai
