this i have GOT to see! you will get mad reps....

Humidity is a big problem with the cooling system he is talking about. the humidity will go way, way up. How this system cools is by evaporation of water. Hense HUMIDITY.. Mold, Mildew.. not good.


My AC unit only uses 6 amps of power when it is on its cooling cycle, which is not that often. maybe 15 minutes per hour. and it can only turn on during the 12 hours the plant has lights on. so only 12 hours. It does not take a very big AC unit to cool a decent sized grow room. I have my turned on at 4/10 power for cooling. this keeps my room at about 75-78F. Perfect....... My plants are showing me their LOVE.

Go Cheap, Grow Cheap..

ok you should have no problem with humidity its the same as a AC but instead of freon in it its water they sell them a all hydro shops but they cost to much like $600 so instead you can buy a radiator and that will cost you $30 bucks at a junkyard im going to have it all together on the weekend im not useing a fan on it tho im going to put it over my intake hole and suck the air threw it my fan will suck threw it really good my fan is 1400 cfm but i have a speed control on it so i can set it at the speed that i want the more air the better

Olds442, I am sorry to tell you, but an AC unit does not work even close to how a swamp cooler works. In a Swamp cooler, the water is ran over the outside of a radiator type section, that has air blowing over it, the evaporation is what causes the cooling of the air. With an AC unit, the REFRIGERANT runs inside tubing, in one section it goes into a vacuum, which makes it evaporate, the other section is put under pressure which makes it condense. I know this to be true.

If you do not believe me, go ask any AC repair man. Putting a swamp cooler in a grow room is not as very good idea in my opinion. Unless you want HIGH HUMIDITY.


Freon is a brand of refrigerant.

what if i have a pump and no airstone? I am just running it directly in.. I am going to order one, however I dont have it yet.. Should i keep it running? its an aerogarden

it will do ok, until you get your stones. But i would get the stone in there as soon as possible.

Some air, is better then no air.

so the stone basically distributes the air from the tube?

Which way do the aerogarden growers here go in with the tube? I was thinking a hole where there is no plant and then just sealing it up
