Closet Grow - Advice/Thoughts? (pics)

Hi guys,

I’m considering a soil closet grow and I wanted to run my thoughts by the site for opinions/suggestions. Please note my drawing does not reflect my timers or the auto extinguisher (didn’t feel I needed to put those in for the plans).

Closet Dimensions

4'L X 2'W X 8'H

Lights

600 Watt Cool Tube (MH/HPS)

Ventilation/Temperatures

For cool air in, I plan to cut a hole in the a/c duct in my attic. Then run a hose through the ceiling of my closet to a vortex blower housed in a 2x4 cube. The vortex blower would be suspended by rubber rings inside the cube to limit noise (in conjunction with a fan dimmer). The vortex fan would then push the cool air to a junction, 1 part of the junction would go to the light/cool tube, and the other would just go into the closet. 2 Standard stationary house fans would blow air around the main chamber.

For hot air out, the vortex fan will push air through the light and into a duct hose that would empty into the attic. There are also 2 passive vents that hot air could escape from. 1 is in the grow chamber, that would allow heat to escape from the grow chamber into the electronics chamber and from there through the vent in the ceiling of the closet which would just vent into the attic.

Electrical

What should I get installed in this closet to run a ballast/light, 2fans, vortex fan? How much power?

Safety

I plan to have an Automatic Fire Extinguisher mounted to the ceiling of the closet that would automatically deploy in the case of a fire (see here: http://www.htgsupply.com/Product-Watch-Dog-Automatic-Fire-Extinguisher-12kg ).

Daaam that watchdog is awesome
i might just pik one up
their legitt dude

you should easily be able to run all of that on a standard 120v electrical outlet. Think about it; TV's, electronics, fridge, computer, ps3, etc. usage can easily climb over 800 watts. Standard 16 gauge extension cords are rated for 1875 watts.

Seems like all the complication involves the CO2 / heat air exchange.

btw I'm not sure if it is in your drawing, but you want your air intake and outtake on opposite sides of the room for best ventilation. i.e. outtake up high for heat and lighter 02 and intake near the bottom with it's cooler air and heavier CO2.

I ran a 400 in my closet that is the exact same dimensions. I have 180 cfm 4" inline that was pulling from filter ducted through vented hood ducted to fan and taking hot air out into attic. In the summer temps were a little higher than I had hoped. I felt like I could have gotten away with a 600 cooltube with a larger exhaust fan (6" 440 cfm). I used a passive intake setup. My closet sits in a small hallway in the room where cool air dumps out so in summer I have to run air during hot part of afternoon. You may want to rig it all up then figure out if tapping into AC line is required? Also you can get a dimmable ballast it will help controlling heat. I took my inline fan and put in plastic storage bin, insulated around it...cut out some 4" holes for ducting and use it as a muffler box and put it up in the attic as well....I also have a fan muffler to help with exhaust noise. Works pretty good my closet is pretty stealth. I also went away from HID and went to LED to help with heat and noise from fan issues and make it even more stealth.

Hi guys, thanks for the info so far. Any thoughts on my electrical needs? I think I'm going to need more than standard A/C.

how many watts do you plan on spending? 600 ain't shit if that's what you're asking. btw, on second look at your drawing... a fan is way more efficient at pulling air than pushing it, so you want the fan to exhaust the hot air out of the outtake and have a passive intake, not the other way around.

I dont really know what you mean. If you are referring to my vortex fan its pulling air from the A/C duct and pushing said air into the main chamber as well as through the light tube.

Can anyone weight in on my power needs? Figure a 600 or 650 watt light, the vortex inline fan, say 4 standard house fans. Will a standard jack run this?

if i had known this was for tomatoes i probably wouldn't have replied, but yes a standard outlet can easily handle 1000 watts or more. Of course, I cannot be held liable if your house burns down...
