Humidity high in 4x4 tent

[40P]

I need some help keeping the RH in my 4x4 down to proper levels. The girls are flowering and the RH jumped to around 68%. Not so good. The tent is in a basement and I'm running 2 70pint dehumidifiers outside the tent. Outside RH hovers in the low 50's but I can seem to get inside the tent down. Any suggestions?

Am assuming your running photos, is it in a room in the basement? I'd open the door of the tent and leave it and close the door to the room. Am not in a basement, but that's what I do here if rH is high.

There is also a product called rotblock that I tested last fall, a foliar spray, it works, but needs to be started close to 12/12.


If their autos, open the door, go to 24 hrs on.

It's a 4x4 tent in the basement. 5 autos and 1 photo that weaseled her way in. I've been using the 20/4 light schedule. I also have two hydrometers reading both top and bottom.

It looks like your early enough to use the rotblock, but it would need to be fairly quick.
I tested it last fall in a 4x4 jammed with plants. Ran around 70% all thru flower intentionally, not one issue.

no... two others out of the picture.
I sucked it up and squeezed one of the dehumidifiers into the tent. Instant success. within the hour I'M already down to 58%.

Itll help, but honestly, am not too surprised the rH that much higher than outside the tent, there's a lot of vegetation in there, 5 in DWC? Bubblin water can't be doing the rH a lot of help. More exchange of air to outside is needed if the door needs to be zipped.

Or squeezing in a dehumidifier... not a lot of room in there, glad its helping.
