    I bought the Spider Farmer 32 pint dehumidifier and it's doing a good job keeping my humidity in tact. Thanks for all the tips

    He wants to remove humidity not add.

    @jaden4306

    25 pints is approximately 3 gallons plus a pint. I used a 9 liter, 2 1/2gal, humi in a similiarly sized room and it was fine. I had to empty it a couple times a day but other than that it worked fine. Does your humidifier have a drain hose? If so you can use a refrigerator condensate pump to drain the humi condensate into and it will pump the water out to where ever you direct the hose. I used one in my setup after getting sick of coming home to a tent that was at 70% humidity because the humi reservoir got full and it shut off.

    If you're deadset on having a humidistat I think Inkbird makes one.....

    Your tent is a 2x2 x5. It's in a room 12x12 correct. Humidify the lung room to the desired humidity.

    Should. I have a similar size lung room and use a 25 pint dehumidifier. It sits in the lung room and not the tent. I like the idea of the condensate pump but have no way to drain that outside. I elevated the dehumidifier and it drains into a 5 gallon bucket.

    My tent is in a 12x12 room. Do you think the spider farmer 32 pint dehumidifier will work in a room that size?

    A dehu inside the tent is not the answer. If you are exchanging air properly the dehu will not have enough time to change the rh of the air in the tent. If you want to change the rh in the tent you will need to control the rh of the surrounding room (lung room).

    Pipe the humidity into the tent with PVC pipe or cover up the light with tape. Easy

    Cover the light with a piece of electrical tape

    Does anyone know of a good dehumidifier with a humidistat? I bought one that I could place in the tent but noticed there's a light that doesn't turn off so I can not use it.

    I do live in the Southeast and yes my grow space is often 85+F in summer and the humidity well into 70% -80%. I grow tropical strains in the summer for that exact reason. That said, if you keep your plants well defoliated and the air moving around, you will likely be fine.

    While I agree that VPD is a good tool to have, I reserve that tool for larger rooms. Small spaces like a 2 x 2 are much harder to stabilize due to the interior size and the quickly fluctuating conditions. If you can stabilize the environment in the lung room your VPD should not be that far off inside the tent.

    Even in my 5 x 5, while I do look at VPD I don't chase numbers. Can it help me in my adjustments? For sure. As you stated, these plants can take a wide range of conditions.

    These plants are called “weed” for a reason. Like all weeds, they are capable of surviving in a wide range of conditions. There is no need to worry about RH being in the 50-60% range. When people talk about the ideal temp/rh/ph/ec/ppm….it all comes with a margin of error that will still let you harvest some good bud.

    More important to your plants is the VPD. You can still get some awesome bud even at 60-70% RH if the VPD is met with higher temps. Your plants will tell you what they need. It’s not always good to force the plant into conditions they don’t want.
