I’m running a 4x4 grow tent with a 1200w viparspectra led light and a 4 inch carbon filter. I have three fans and two dehumidifiers in the grow tent but i can’t seem to get the humidity below 70% during flower. The humidity where I live is around 80%. Does anyone have any ideas how I can lower my humidity to suitable flowering conditions?

Well if your starting with such a high Rh your going to have a battle with humidity so all I can see is if your using your houses ac then blow that air outside. Need to get bigger dehum units buts you’ll be throwing it all out the window literally. Need to control heat.

Yep, the humidity in your room is what matters, those tiny dehumidifiers don't do anything. You need a bigger dehumidifier for the room that the tent is in.

Do you think it is possible to make a chamber where I can place the dehumidifiers in and then intake that air into the tent?

Maybe try moving dehu in front of one of the vents? Is your carbon filter and inline inside your tent? Passive?
