A portable air conditioner would control both humidity and heat. They typically have reservoirs/drains to collect and remove humidity as they cool the air. I have a small unit for my tent as my HPS lights crank out mega heat. ---

I think I got mine from an Aldi a while back, I can’t find them online, but this is pretty close to what I have.

> [@REDBUD82](#): > > what should humidity be at at this stage Temp and humidity go hand in hand to optimize vapor pressure differential (VPD). VPD allows the plant to transpire properly. Transpiration is vital because that is how a plant takes in CO2 and expels O2 and H2O. This expelling H2O pulls moisture and nutrients from the grow medium into the plant. Both leaf and air temp are used along with relative humidity. Use a VPD chart to determine humidity for a given temp and the stage of growth you’re in. Be wary of charts that don’t include leaf temp. > **[VPD Chart](https://vpdchart.com/#F,61,83.3,82.4,0)** > > Vapor pressure deficit (VPD) chart & calculator for horticulture in controlled environment.

I was reading another thread and someone mentioned an infrared thermometer temperature gun to read the temp on the leaves. I was planning on buying one anyways for some other projects I have planned. Amazon has these for about $40.
