I would get a regular room thermometer to be more accurate. I don't know what your budget is like but you could also get a "ACURITE" weather station like I have with a remote sensor. It tells you the air temp, humidity and even bromidic air temp. It even has a memory button that will tell you the high and lows for the whole day. I got it at Wal-mart for 30 or 40 bucks. I have the remote sensor outside but you could keep it near the plants. It also has a flat panel led moniter that ether mounts to a wall or you can set it on a table or desk like a picture frame.
i used a mercury thermometer.

If you need a custom fit, that's easy to figure out also. If you need to run the ventilation outside or somewhere the heating and AC ducting works great, and you can custom fit it to just about anything. Send me a private message If you want some help with that, just give me some details of your setup (pictures would help also) and what kind budget you are working with and I will try to give you some ideas.
it was $170CAD plus shipping. already bought and in use so i wont be getting rid of it. it is 172cfm and i havent seen anything that powerful in this size at any home improvement store.

To fix this you should first figure out what is causing the water temp to rise, its absorbing heat from somewhere. There are a few ways to cool it down that I know of including ice (that can dilute the solution) that are inexpensive. If you can keep it from warming up in the first place that would be the best defense. It would help to let me know details like how many gallons of nutrient solution, the air temp of where the reservoir is stored is, if it's inside or outside, what type of container it is in. I also don't know how your set up, if everything needs to remain in the grow tent or can you move the reservoir outside of it.


that is my setup.
i think the water is getting warm because the buckets are black. i thought about spray painting them white but that would cause a disaster because i would have to wait for the paint to dry and i have nowhere to put the plants in the meantime. also, if i paint the lids i am afraid of the paint chipping and getting in to the water. i think the best way would be to use a white bucket and use some sort of black plastic liner inside... or maybe even just cover the bucket with a white plastic bag instead of painting it.
i would need to keep the whole setup within the tent as there is no room in my house for this (my parents would kill me) and i cannot move it outside (they will kill me again). the air temp of where the reservoir is stored is 27C, the same temp as where i measured the temp at plant/bucket level.

the only difference with my setup and the pic is i have moved the ballast outside the tent.
