Halo,
long time reader, now time to make my first post. Wish it had a more positive undertone, but it is what it is...
Heat problems: I started my grow with a 1 square meter growbox from homebox.
Everything had been going fine, and then I decided to go ahead and change my hps from 400 to 600watt output.
Next thing I new my room was at 33degrees C and above...No good and some plants started to show signs of heat stress and even burned leaves. So an order was made for a 430kuub exhaust fan (was running a 300kuub one) with a matching odour sock.
Day after installed it all, temp still gets up to 30degreesC. I have a big oscillating fan opposite of my intake, and a small fan aimed directly at my hps, which is hanging under my adjust-a-wing. Lights at 65+cm!
So decided to hook-up my old exhaust fan to the intake for more fresh air, and now it gets down to 27C, still two degrees hotter then I would like (running Venom OG and P.C.K., both with kush influences and they really dislike heat). And the exhaust fan is running at 100procent the whole time(hooked up to a thermostat set at 24C). Also, the roots of the plants never get over 21C because of the big amount of fresh air coming in...
So my ballast is a dimmable 600-400watt lumatek. It has been acting up, shutting down at random, so I had to replace it again with my 400watt ballast. Now, with the intake fan installed, I can hang the light as close as 20cent without the temp going over 25C.
In two days I will get my replacement lumatek, and was wondering if maybe the previous one was faulty making the hps run a lot hotter then it was supposed to?
Or any other ideas how I might get my temps even more down would be great...
