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 instead of seedlings
Trying to germinate our seeds right into the soil, planted 72hrs ago. Covered with mason jars and now have white mold starting to grow on soil. The temp has stayed around 22 and the humidity around 65%. Should I remove the seeds and go to paper towel method instead?

Should I be worried?
I'm getting green mold on my root riots because of overwatering, i made the transplantation but I should have waited till the roots got deeper probably, I irrigated too soon. I irrigate now only when it is a bit dry. Is it bad ?

The Red Mandarine have leaned too much respect to each other. I think it was due to excess light, to use a 600w led spotlight from the beginning. Next time I will use fluorescents or a led of 125w that I have

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 ?

Should I put harvest into jars early?
Should I put my harvest into jars insted of hanging? I harvested 2 days ago and my humidity right now is between 60-70% with fan and dehumidifier. I wonder if the buds would be better in jars with 50% humidity packet. I'm afraid they will mold hanging in the house. Rain all wk.

Could this be mildew?
Hi all, I've been stressing out about high humidity levels in my tent, and a chemical smell when I smell my fingers after running them through the buds. Could this be mildew? Or just very frosty buds? On the microscope I see thin "hairs", but looks like undeveloped trichomes...
