Howdy everybody. I've been reading around here for a few months now, gathering all the information I could, and I've learned quite a bit.

I'm an experienced outdoor grower, and indoor soil grower, and now I'm making my first jump to hydroponics. My living situation dictates a closet setup, so that's what I've built.

I'm doing a small, 3-plant, waterfarm system using all the bells and whistles (CO2, overkill ventilation, carbon filtration etc...). The whole thing is contained in a large "armoire" that's divided into 3 separate chambers (see pics). The closet is about 80% complete (still need to add mylar, hang the filter, and run power and CO2 lines).

The grow chamber is 31"w X 20"d X 65" high, and I have one 6" 265cfm axial fan on the bottom left side for intake, a 265cfm Squirrel Cage blower sucking air through my carbon filter for exhaust out of the cabinet, and there is a 190cfm squirrel cage blower for running air through my light hood (400W HPS with SuperSun hood).

I think I'm covered as far as ventilation goes... my only questions are about CO2 and basic watering schedules.

For a small setup like this, how should I run my CO2 system? It's a hydrofarm regulator system (slow release)... but it's designed for much larger areas. I have a controller that will shut off my fans when it's time for CO2... but how often should I pump in CO2... and how long should I try to allow before kicking on the ventilation system again?

And for watering, I'm just wondering if there are any other waterfarm users in here.. and I'm curious how often you run the watering system?

I'm thinking one hour on, one hour off... like the manual says, but I'm wondering if anybody else got better results with another schedule.

Here are the pics (sorry for crappy cellphone pics... my digi is being borrowed):
