Im in the closet lol so I don't monitor a lot of things, humidity being one.
I know for sure it's not too humid in there due to the temps and the fact that the air is constantly moving, but I don't know if its humid enough....
My leaves aren't dry so I don't think I have an issue, BUT here's what I do for some piece of mind....
i bought a few gallon jugs of water from the store and kept a few after using them, so I've got like 6 in all. After I water the plants I fill them back up immediately and let them sit.
I figure it serves a dual purpose.....evaporating the chlorine from the tap of any is present, and contributing even if very minute, to the amount of moisture in the air.
so I have like 6 gallons or water sitting in the grow space without a top....maybe it helps??
Def. haven't had any issues with chlorine or choloramine.
But your prob already bought a humidifier huh lol
