I too have had humidity problems just recently. Mine was getting to about 59% I think was the last reading I had, and this started to worry me. First thing I had to take into account, was where all this moisture was coming from. I had forgotten about a small bowl of water that I was keeping in the room to keep it higher, so I took that bad boy out, and I dropped to about 55%. I also have my plants set up in such a way to where the pots are in larger buckets, but are on risers, so that way when I water them, I can reallly water them, almost like a leach, but only with one gallon. and the water drains into the bucket below, but does not rise high enough to touch the bottom of the pot. So after a nice water, that means I have 3 buckets that have water in them which contribute greatly to a lot of the moisture in the air. I also have a circulating fan, but that only does so much. I happened to find a nice dehumidifier in my house which had a humidity control option. So I positioned the dehumidifier half in the room and half out. My humidity is at a consistent 35%, I can water how I please now, and it acts as an exhaust as it is sucking the humid air out of the room, and blowing the hot out. Wonderful thing to have as I do not worry at all about humidity, and I believe I read somewhere that dropping the humidity real low at the end of flowering is a great way to produce more trichomes. Depending on the size of your grow room, a standard dehumidifier should do the job. If your room is slightly larger, and you have the room, a couple small ones positioned close to your plants should really do the job. My room is fairly small, about 5'x4'x7', so the unit size that I have, (standard home size dehumidifier, 1 1/2'x1 1/2'x2 1/2') really does the job well. Best of luck on your humidity issue, hope my story has been a help to you in some way or another!
bcals0087 Reviewed by bcals0087 on . Humidity and flowering.. I was just wondering what is the highest level of humidity has anyone flowered their plants with without dealing with mold or different problems..like mites, fungus etc., I'm wondering because it's gonna suck for my flowering if I can't keep it down. The bigger my plants get the more the humidity I have. Luckily it hasn't reached over 60% but I really hope it doesn't get any higher or I might have problems. I have on a dehumidifier but it really doesn't help that much lol. Any other things I Rating: 5
