What is the temp of your res??? Have you tried putting a desktop fan next to it blowing down across the top of the water? This is evaporative cooling and it works very well for about a 10 degree drop.

Hey Weeddog. would putting in a air stone help with that as well? That way would it not also help oxygenate the nutes and promote the evaproative cooling. Just a thought as I'm growin in my attic and it would pitch me a fit as well.

No, the airstone wont help with the cooling any but I use one in my res to help oxygenate. The fan really does work. I read it on OG over a year ago and decided to try it this summer.

More oxygen should help the plant with the higher temps as well..... I keep my rez sitting on concrete... buuut kinda hard to do in the attic i guess.

got a couple quistons mang

1. did this raise your Rh in flower and

2. you have any probs with lights and a open rez or was the rez not in the grow room?

10 degree drop sounds great if'n you had no other probs

pop bottles of ice are good for like 2-4 degree drop

grow on

My res is just outside my flowering box. Never had any problems with humidity altho I'm sure it raised it a little. Kept my grow room at 78 degrees and my res would hold a constant 68. Ive hooked a digital thermostat up to my fan to keep it from getting too cool. I have used bottles of ice in the past and you have to really keep an eye on it. The thermostat makes it all automatic. I had to modify my thermostat to get the sensor in the res. I also finally modified my reservoir lid (36qt cooler) with a 4" hole and fan attached to it blowing right down into the res in the middle and 4 smaller 2" holes in the corners. You can feel the air blowing out the smaller holes. My digital control stays between 68 and 69.

BTW, I use the same setup in the winter except I use a small aquarium heater to warm up the res to 68. Bought another cooler so I could change to a no hole lid for the winter time.
