First off, please bear with me as this may be long winded.
I have an 4'x8' tent. I have 1 600 watt hood cooled with an 6" inline fan pulling 400 cf a minute. (my second ballast will be here today!) The fan was inside both ventilating the tent and cooling the hood. I couldn't get my RH above 40% and my 8 plants looked like it. The leaves were dry looking and had almost a leathery feel to them. So I decided to try something.
I took everything out and started fresh. I put an 8" duct booster as an outlet in one of the upper ports. It was to be ported outside the house. I then located the inline fan outside of the tent and ducted it through the hood and out the tent. I fed my plants and closed it up to see how it worked.
It didn't take long before the RH started climbing. It soon settled at 60%. OK, for how long. It was 75° and 60% RH until I went to bed at 11:00. I woke at 2:00 and checked on them. The temp was fine at 67°. The RH was 97!
So I opened one of the end flaps and went back to bed. It lowered to 55%RH (ambient was 41%.) Temp was fine. The lights and fan came on and it is 73° and 60%.
My question is what is the best way to keep the humidity down without putting my dehumidifier in? I do have a speed control for the inline coming so I may have to put the fan back in when I have both hood set up. But I like the fact that the temp in my den has raised 4 or five degrees since making the change. So I have two ideas.
#1: Put a "Y" in the duct with the single end trailing. The idea being an injector in a power washer or a hose end fertilizer pulls the material out due to ? Is it possible it will work with 300 to 400 cfm running through? Then I could dial in the inline fan with the speed controller for night time and turn off the 8". Or not need it at all.
#2: Cut a piece of Panda film an inch smaller all the way around my pot size, put a hole in the middle leaving plenty of room for the stalk and putting a slit in it to be able to put it on the top of the soil. The are in fabric pots so I am thinking that the soil will be able to breath well. That should stop some of the evaporation and hopefully allow the soil to dry out in a timely manner. This would be my first choice. Has any one tried this before or know of any problems that it could create. But I am not sure that I want to be the Guina pig on this one and potentially kill my plants.
Any one have any other ideas. KingJohnC? Heady? Cannafan? Any tent users? I am sure that any one using a tent with soil has had this come up.
Ok, long enough, thanks!
