Harmful mold/rot/fungus on degrading old plant matter?
Flex1
started grow question 4y ago
Mold/fungus? Harmful? Haven't seen something like this in my living soil and I suspect it could be from high moister or humidity level. Its only seen on old dead cover crop.

Not harmful at all, actually beneficial for your soil biology.

I wouldn't worry about this... not at all... if it's just the old, dead cover crop, it's naturally decomposing... Good luck!

Update: seems fungus related not mold. Not certain it's harmful rather just part of living soil.

Best way to control humidity?
I have a 4 inch inline fan blowing in air at the bottom, I have a 4 inch inline fan sucking air out the top and a 4 inch fan to circulate air inside and a large 300 foot air dehumidifier in the tent but my humidity is still 50%-60% constantly. What am I doing wrong?

Mold on soil ?
On day 36 I discovered some strange white stuff on top of the soil in only one pot. Looks like mold and the plant seems not to be infected. Two days ago I gave both of the BioTabs Bactrex and Molasses as scheduled. Does anyone had this issue before ?

How do I get my humidity down?
Help! It's raining for another week, and our humidity is around 65% to 75%. Should we use more fans, or what would you recommend? Dehumidifiers? Thank you in advance.
