@Experimentgreen, I already use & EM-1 in veg & first 2~3 weeks in flower, last year I had big issues with mold, so I purchased the EM-1 and it worked, for extra protection I'm planning to integrate the General Hydroponics Defguard, so I will have 2 layers of protection from mold.
+ I also purchased a dehumidifier for the flowering room now.
