Hi, so I am on my first grow and have had multiple problems but that's part of the experience right? I built a stealth double stacked Rubbermaid micro,as shown here... https://www.icmag.com/ic/showthread.php?t=100698 I built a scrog and am using what I will call a hempy trough. my temps are low to mid 70's but my humidity is run around 60ish... today I found the start of PM,and after some research and weighing my options I have decided it would be best for me to start over and try again.I b run 100% perlite in my hempy and believe this is a big factor in my humidity problems.My question is how do you control humidity in a micro system and if I switched over to a DWC would this help due to the fact that my water would be more contained and therefore keeping my humidity more in check??? or are there other options I should explore? Thx for your time....

Yea...I thought starting over would be a better idea but still don't want this to happen again so I'm trying to curb the problem.

My best advice is get the air moving. I could'nt create a massive blower system so a found an alternative. One Christmas I got a smokeless ashtray. Never used it, until I put it inside my cabinet. It has a small fan and runs fairly quietly. Humidity problem vanished. With the plants & CFL's it gets hot and damp inside. Running the ashtray blower for a while daily created enough movement to work.

I run a redgreenery modified setup, a low tech version of what you described above, https://www.icmag.com/ic/showthread.php?t=31605
I found early on that I had to add PC fans inside the grow area to keep the air moving and fresh inside the box. Also, my setup is in a semi-finished basement, and deal with high ambient humidity. I had to solve that problem by adding a dehumidifier to the basement.
Good luck.
