When you turn on Lights you turn on heating , and when temperature goes up humidity goes down , or relative humidity .I guess big grows might behave differently but small ones in my experience have lower humidity with lights on .

5:20 Wrong. You want to raise T when dealing with high RH. Temp and RH have an inverse relationship. Warming the air creates more volume of air space to hold the same amount of water vapor which equates to a lower percentage of water molecules in that given air space. Higher T, Lower RH. Lower T, Higher RH.

Thank you for pointing that out @z Hawkins. You are correct. Nate said that backwards. Given a set amount of vapor in the air a higher temperature will equate to a lower RH than a low temperature will. Thus raising (and not lowering) temperature will bring RH down.

Although I don't know exactly what size Dehumidifier I need at least I have an idea how to start calculating size Maybe you can help. 15 square feet being exhausted plant uses one gallon per 3 days the internal temperatures 81 external temp is 69. RH wants to stick around 60 lights on/70 Plus off. I need to be around 50 preferably 45 even with the exhaust I can only get it down to 56RH.

Glad you enjoyed it! In answer to your question, you may need to look at a dehumidifier, an exhaust fan is only going to reduce the humidity to the level of the air outside the room, because this is what is replacing the humid air that is exhausted. Depending on where you live, a Quest dehumidifier may be the right option or next step.

Hi Nathan, there are a few ways of tackling a problem with higher relative humidity in your grow tent: 1. Try installing a small fan for better air circulation within your tent space. 2. Try reducing the amount of plants within your growing space. When plants are actively consuming light, water, and nutrients, they go through a process called “evapotranspiration”. Evapotranspiration is the process in which your plants release water molecules from the underside of their leaves called “stomata”. Depending on the crop, proper spacing can dramatically reduce the amount of humidity build-up in a growing space (and reduce the chances of fungal outbreaks from occurring)!

Yeah, if humidity is high you don't want to lower the temperature because the water vapour will condense on the plants. I think he meant to say raise the temperature. He said it with such confidence I had to watch it more than once to think about what he was saying.

Hello Bright Agritwch team, Can you help me size the appropriate size of dehumidifier for my system? I am thinking of building an indoor stacked type aquaponics in small facility sizing 3*3m=9m2 area. The Dwc system would have 400 heads of lettuce growing with 800 horizontal rectangular shaped fish tank. Also it has bug window facing south. In winter the room temp drops down to 18 degrees celsius inside facility while outside is -35 to 40 degres celsius at coldest. Now the indoor temp is fluctuating between 22 to 28 degrees during the day and night times. Thank you.

Don't humidify. If it's still really low in your growing environment, the easiest thing is to wait until your crops are larger and more mature- most growing environments will become very humid once the plants are rocking and rolling. You'll find yourself fighting to bring it down more than you want to bring it up.
