I've got 4 autos under a 400 hps and some cfls. The humidity ranges from 20-30%. I know it should be higher. I have a humidifier that I run which brings it up to 50-60% although I cant refill it quickly enough so it drops back down. My question is whether it is better to keep a constant low 30% all the time or have the humidity fluctuate between 20-60 when I am able to refill the humidifier? Thanks
During veg is good to have 50-60%, in flowering 30-40% (dry air increase thc production) Depending on which stage you are, you can choose the "closest" option..
