I was looking for some help from fellow ICMag members on the design of my new cabinet. What I am trying to do is have 3 seperate sections. One for Grow, one for Mother, and one for Veg. The main problem I have is that I would like to incorprate a 5600 BTU A/C to help keep them all cool. The cabinet would be located in my outside shed and it gets 110 degrees plus in there. Right now I have the a/c blowing directly in the grow cab, there is a Can33 filters and a 6" Elicent sucking in from an air cooled hood.

Problem with that is the other 2 cabs are stuck sucking in the ambient temp. from inside the shed. Which can be around 100 or so. The setup works great in the fall,winter,spring, but summer is almost useless.

What I want to do is somehow make it so all 3 cabs can suck in the cool air, you know, maybe make a central empty cab that would fill with cold air, then the fans from each can would suck in the air from there. That way it helps keep out bugs, and I can make the entire cab air tight. But do you think there would be enough suction to use a passive intake. Or should I setup the fans so they blow into the cabinets, then in the flower room have and extra for exhaust.

Not sure, but I think you get the idea. So, let me know what you would do.

Thanks guys.

can you not insulate the shed and cool the whole thing? then all 3 cabs will be provided with the cool air, and the shed air will only be refreshed from the outside world so the aircon exhaust (if its a single unit) wont smell

what colour is the shed? would a lick of light colour help it? perhaps not beach hut white, but a sky blue?


can all 3 boxs have a 6" inlet hose? the 3 hoses can cram into a 10" and the 10" can be hooked onto the coolers outlet. if the 10" dont draw away all the cold, the rest will cool the shed. if the 10" draws to much, it will take all the cold, and some shed air, but that just means your aircon can't do that volume of air, so wont work anyway with that extraction rate. well...it will work, it just wont chill 'all' the inlet air


where does the aircon get its air? is it having to cool the hot shed air, or does it get outside air ducted to it to ease the load? its fan should be beefy enough to drag air down a duct of fair proportions, esspecially as it will be helped by the extraction fan/s to get air going in that general direction anyway
