Humidity out the tent is low 60% not higher than 67% i have 2 6" inline fan around 800 cfm tent is 7 foot high i also have 2 8" inline but the negative pressure is very strong if I put the 8"What's the humidity of the air you're pulling in, and what CFM are the exhaust fans? The exhaust fans should recycle the air in the grow area in about 1-3 minutes. 10x20 is 200 sq ft x the height of the room will give you your cubic feet, assuming an 8 foot ceiling thats 1600 cu feet, bare minimum would be just over 500 cubic feet/min on the fan(s).

I have another 35 dehumidifier i will put that one also to see if it make a difference thank you for your advice.At a certain point dehumidification will bypass stand alone 35-50 pint dehumidifiers.
Based on just simple recommendations you would need 3 50 pint units that would have a heat load of 2500 watts.
My recommendations are to get a professional HVAC company for a 200sf for profit grow concern.
Can you go more in details don't mind trying something that works from other the pic is night timeIt might not be enough or just not applicable to you being in a tent ( im in a shed) i played around with some positive pressure, inlet fan on a little higher than your exhaust fan. But then you start muffin all your other parameters lol. Something for the think tank though!
might be worth a shot. At least to see for yourself : ) im not an expert at the science but simply put, turn your inlet fan on like “6”and your exhaust port fan on “3”. That creates a positive pressure within in the tent which squeezes some of the moisture out of the room so to speak (and that could be off also). I would have to go back and look at my thread to see how much it was dropping the humidity, but it did work to some extentCan you go more in details don't mind trying something that works from other the pic is night time
Lamps are at 60% low already only 614 ppfdFirst, focus on the exhaust. Make the outlet as large as possible. Make the supply passive. Also, place the channel ventilators inside the room. Install a smaller but longer duct on the entrance side.Try lowering the lamps and reducing the power, which will help lower the temperature.
i have 2 4" inlet fan that I can put it in the floor sucking air I'm going to test it and seeThis thing doesn't work. It only increases plant transpiration. Make the air masses move with powerful channel ventilators.Use powerful fans inside, like this white one, to increase the air speed, but don't point it at the plants.
You have a really big room, and you'll need more. try to implement it in the next episodes.i have 2 4" inlet fan that I can put it in the floor sucking air I'm going to test it and see
I have 2 14,000 btu ac pumping could air insideWhen my humidity gets high I just turn on my AC. It works pretty well in my situation and I'm in the backwoods of PA where 70-80% outside is the norm. I use one of those window units.
I was thinking the same thing I was just today looking at a episode from jug dealers podcast where they are explaining basically the same thing you are explaining which how much I'm feeding is the amount of water I need to dehumidifier i just got a new 35 pint i haven't made a custom exhaust box due to the heat to send out the tent after I make it i will test it to see if that works thank youThis could be a black box type of analysis. In this case, the tent is the box. To maintain a stable relative humidity within the box, the amount of water that goes into it must equal the amount of water that comes out of it. A reasonable estimate might be that a mature plant transpires a quart per day. At that rate, total transpiration inside the box by 48 plants would be 12 gallons per day. To achieve a stable RH, the total dehumidification capacity would need to be at least that much. A 35-pint dehumidifier can do 8.75 gallons per day and thus would be inadequate.
