oh my god! I couldn't stand a jump like that in my electricty bill. I assumed (incorrectly I might add) that my bill would triple perhaps, and I would have to sustain that until my factory is fully functional. I guess I won't be imitating your grow any time soon. I am certain there is a happy medium to be found here. I am sold on hydro, I think your friends system is a great deal. I just need a scaleable design where my electric bill would jump just 3 to 4 times initially and as I realize some of the fruits of my labor I could gradually expand it to accomodate a higher elec. bill. Can I email you?
