Hey everyone. I have a make shift grow room set up in my shed right now. For my next grown I want to get a 5x5 grow tent. I already have lights and fans and a dehumidifier. My question is this- what else do I need? From the looks of it most of these grow tents have a carbon filter vent fan. Does that act as the dehumidifier Fan too or do I need that in addition to my fans and dehumidifier? Would love to see someone’s set up if they want to share. Thanks. ---

Carbon filter is typically used in late stage flowering, like week 4 or 5. Not typically used to dehumidify a tent. ---

Gotcha. So I would still need to incorporate my dehumidifier during veg and flowering to prevent mold, etc? It’s kind of a big house type dehumidifier so would I just wheel that thing in to the tent or leave it outside of it? ---

Without knowing the specifics, I would say the room its in, or the room your intake fan is in. What is your average humidity in your city? ---

Live in the south so in summer it gets pretty high. Was going to try some autos over the winter so not sure humidity will be a problem. More of keeping it warm enough will be my issue till next spring. ---

Chances of needing a humidifier are greater in the winter than a dehumidifier. Since most heating units remove humidity. I use a small electric space heater and supplement with fans and a humidifier. ---

I would get your tent set up, with the fixings, and see what the hydrometer tells you, make decisions from there. ---

I used a small fan and inline fan attached to a carbon filter for smell and heat control in my tent this year. I used a full size dehumidifier right outside of my tent which seemed to control humidity levels pretty well. If it happens to be a humid season when you’re growing just be prepared to empty it often or have it where it can automatically drain. Hope this helps. Happy growing!
