I just finished my grow fridge yesterday and I'm wondering if the ventilation is working too well since the temp inside never gets beyond 4 or 5 degrees higher than the house temp. Went to bed last night and the temp in the house was 70 and when I woke up this morning the temp in the fridge was only at 74.5. Is this going to be too cold for plants? I've got a Can2600 carbon filter attached directly to a suncourt 6" inline vent fan (I screwed it on there with a bit of weather stripping between the filter and the fan to seal it).
It then goes through 6" flexible ducting and into the end of the light reflector. I plugged up the other flange on the reflector and cut a 6" hole in the side of the reflector and installed a flange (I used the disk I cut from the side of the reflector to plug the flange on the end and used metal tape to seal it up). I didn't have enough space to have ducting on both ends of the reflector so it had to be modified. An easy job with a 6" hole saw and a strong drill. The air comes out through the new flange and gets vented out of another flange thats mounted on the top corner on the back of the fridge. The only intake is a passive darkroom baffled vent mounted on the rear of the fridge at the bottom. I took two of the baffle panels off the vent for better airflow and it still keeps the light inside.
This was incredibly easy to do and the heat problem I thought I'd have isn't even a factor anymore. I'm only using a 250 watt hps, but since there's almost no heat build up I could probably get away with a 400 watt.
And btw, if anyones wondering, the Can2600 filter is easily refillable unlike some of the larger cans. The guy at the hydro store was telling me I'd have to come back for a new filter every 14 months or so since they weren't refillable. Bullshit. This is the last filter I'll ever have to buy.
And the fridge is almost dead quiet with the suncourt inline fan inside running full speed. You have to put your ear to the fridge to hear it. I also bought two serious blower fans to try (a 4" and 6") and they were WAY too loud and took up too much space. Not only that but they cost over a hundred bucks while the quiet little suncourt was only $35.00 at Home Depot.
