First off Hello guy's I've been lurking for a while now getting ideas for my own cab which is built and running however im running into an issue. My cab is made out of a file cabinet completely gutted, homemade ebb n flow, speakers (yes speakers to hook up mini ipod for the ladies ) a 120 mm intake fan and 3 80 mm fans built into carbon scrubber to exhaust. Lighting is 90w UFO LED now here's the issue... Leaving the LED on with fans constantly running temps reach 94-97 with 0 percent humidity. On top of that I have a 6 inch fan aimed down on the ebb n flow. Mind you all this is a dry run, I had issues with leaking on the ebb n flow but they have all been pluged up. Now here's my idea, I've been researching cooling idea's and came across a peltier cooler. Now I know that with the peltier one side get hots while the other is cold. If I get an aluminum heatsink and bolt two 120 mm fans on the hot side it sould bring it down to a point where it would cool the other side faster, now if I put the cold side heatsink to my 120 mm it should bring down my temps but I dont really know if it would be woth it and would it bring down my temps to the required level 70-75. The ladies are currently in a pc planter but I was trying to transplant them to the cab asap but as you can see hit this hurdle. Any Ideas, any help much appreciated Green Goblin420
we need to know how big the cab is and what the cfm 's are on the those fans to have better idea of whats going on. i will tell you that those ufo do put out heat not a lot but in a small space its cumulative and you need to vent the space more than you would think
Could you post a pic of your setup? Im looking forward on this LED light for a small cab also, u could help me with it
Ask and ye shall recieve... the 120 mm fan brings in 110 cfm while the three 80mm bring in 90. The dimensions are 2.1x 1.3x 4 the black strip is velcro which I use to adjust the fan either up or down, also I installed a PWM for the fans but will probably switch it out when I pick up the peltier. Black thing is carbon filter with activated carbon inside and the two bottles are for homemade c02 which will do next grow. Also I added a fountain pump to help purge whever nutes would be left hence the circular thing on the ebb n flow and the spout is an easy filler. Now I'm aiming for stealth because I have very inquisitive family members so the less noise the better.
update: Figured out just leaving my closet doors open keeps the temps at around 80-82 degrees while at night drops to about 76 will update with some pix soon As promised:
