Any ideas for dealing with humidity with a semi-outdoor grow in a high humidity climate? 4x2 tent in an outside shed. Air intake brings in outside air, and exhaust is blown into the shed. Outside Avg Temp 68 Avg Hum 80% <--Typical Environment data for last week attached

Hey did you ever solve this issue. Having a similar problem. Plenty of ventilations and fans but if the oustide RH is high then undoubtedly going to struggle to keep it down. The only solution I am finding is adding a dehumidifier into the tent. A temp solution some people are suggesting is to add rock salt in a container.

Humidity won't go down because of clay pebbles ?Though my extractor is at high speed, I have a hard time with controlling humidity, I hardly go under 68%, specially during the night. Probably it's the clay pebbles since the pots don't have a lid. I placed the temp/humidity probe near the tallest leaves. what do you think ?Bruce Banner - PC controlled system

Mycelium or Fungus - Too much Part 2I am seeing a ton of mycelium on all of my autopots. Because I have a bottom feed system, it is hard to keep my top medium wet without getting mold. Is this going to effect my end result if I do not do anything about this? Should I leave it alone or put sand on it? Thanks allAutoPot - Think Different & Auto Amnesia
