So far here's what I have in the build:

Chiller - 400
Pumps - 150
PVC and misc - 90
Sprayers, grommets, hose, connectors, pots, inserts - 150
(2) 45 gallon res - 60
RO system - 150
AN nutes - 120
Miscellaneous yet to come - 100
Meters - 180

I'll have just right at 1400 in this project.

Like Earl asked.... "How fast can you afford to grow?"
