Personally I just let nature take her course with my crops. I don’t do a pH check. I don’t use a dehumidifier nor a humidifier. Now I did order a pocket microscope. I guess I’m the odd ball as I’m trying to keep the power bill at a manageable cost.

Now I did add a 5k btu window ac that sits on a bucket, As this side of the house has poor AC temps. Add on aka shaft construction. Now that I know how to do SCROG, my amount of the ganja should get a better productions. I am planning on changing my lights to a HLG 260xl as suggested by several members.

Who knows I may change other things that I don’t do and make it on the to do list.

Do you have an exhaust going? Here is a chart hope this helps, it is for Flower.
Happy Growing !

Keeping your plant squarely in the middle of the Vapor Pressure Deficit ideal range for the stage of the plant will help uptake nutrients and keep the plant happy and growing. It’s another piece of data you can use to tweak the grow.

Early flower should be 78F/60% or so RH.
