tempature questions please help.

thats too hot get it down to about 80 with lights on

 

I too have just started a microgrow in a cabinet. It got up to about 90 degrees or above but then I shut off a useless light I had running and put in an old xbox 360 fan that keeps it at about 83. And my seedling is looking nice and green on the 5th day with already its second level of serrated leaves starting.

 

hey gatgrower are using a computer power supply or did you wire the fans up to a 12 vac/dc adapter? becuase if there wired to a wall adapter then check the amount of milliamps (mA) your adapter is rated for because if you don't have enough your fans will run slower and wont exhaust as much hot air out of your case i know because this is what happened to me after i got the right adapter my temps dropped 6-8 degrees. So you need to figure out how much mA your fans use, my fans are rated at .37A or 370mA and i have 4 of them so 4 x 370mA= 1480mA so i need a 12v adapter with a least 1.5A to run all my fans at full speed but its always smart to get a adapter that has slightly more mA than what you need just in-case you want to add 1 more fan. you can find these 12v ac/dc adapters at radio shack a 1.5A or 1500mA adapter is $25 and you have to wire them up yourself or you can go to the site i went to and order a 12v 2A/2000mA for $14.95+ shipping and its pre wired with a 4-pin molex connector!! oh yeah and this is my 1st post!!




adapter= CG 110v AC to 12v DC Power Supply with 4 Pin Molex (2000mA)
