Are you running your can filter constantly. I ran my filter and can fan 24/7 and had temp rise up to 92% and humidty drop to under 50%. Asking around some mention to only run filter and can fan for a certain time so I started to run 5min every 2hr, and my temp stabilized and humidity is staying around 50-60%. The only issue is that I am starting to smell the plants as I get closer to the room. I am now test to run 5 min every 1hr to see if that works.
I also am afrist time grower an the best thing I found was this site it has help me tremendously, I took on areo growing and build my own system and from all the info on this site I must say I am impressed even pat my self on back. I have pic but computor is so old ( windows millium) sometimes it frezzezz when trying to ready FROUM but I am working on new and will up date with all pic even start a log, also still learning who to work my way around this site. I am not saying or telling you my advice is right, just passing on info I have rec. One good advice I rec was to make sure that the PH is at correct level for nutrients to mix properly. This makes a very big difference, plants seam to grow much better, faster,greenner when PH is on. I keep it around 5.5-5.8, good luck I spent days reading and looking at good and problemed grows that had help alot. Good luck I'll keep looking out for you.:stoned:
