Dehumidifier option

Looking for dehumidifier option for 4x4 tent. Just started flower and humidity rarely drops below 70% even with exhaust fan cranked to high. With 4 13g pots there isn't a lot of room either. I have light boxes I made over each side vent and have a huge dehumidifier parked right up to one that's pulling a ton of water, 6g+ daily and lowered the rh in the entire garage 10% but that's only down to 65%. Will something in the tent help or am I gonna have to lower the whole garage to appropriate level?

Thanks for any suggestions!!

Only if you are not exhausting the tent. So thats out because you would be exhausting the air as fast or faster than it's being dehumidified plus it would add heat in the tent.

What is the RH% of the intake air from the garage? We need to dry up the air in the garage since the tent is pulling from that.

What are your temps running? It's important to remember that cool air holds less water so simply raising the temperature of the air will make the RH% drop. So run as warm as your plants can tolerate. Also cool is very difficult if not impossible to dehumidify due to the lack of temperature differential of the air and the dehumidifier evaporator coil. Placing the dehu up high will make it more efficient since the air is warmer up high.

I have just purchased the meaco platinum range 12ltr a day dehumidifier low energy only runs 160w and has a humidistat on it so I set to 50 percent, it drops it to about 45 then shuts of for 30 min then checks the air again to se if it has raised much and if not goes back to sleep for another 30 minutes. Great investment, it was a little expensive but worth the money so save bud rot or mildew. £179

Probably only used 25p a day
