Im thinking tapping air from a bathroom duct in my house as a intake to my tent in garage to help heat and cool as needed. Right now my low temp is getting to around 56° and my high only 72°. I need these 10° warmer. I have an AC infinity "4" duct fan and 2 smaller duct fans if needed. My garage temp stays around 56°. I need to also bring down humidity which is hard to do with 56° supply air without a dehumidifier. Anyone ever try this?
Its foggy and rainy here. Theres high humidity in the air. Dehumidifiers are too costly. My thinking is if I can keep the tent around the same temp as my house I should be gravy. Heated dehumidified air in winter the same cool air in summer?
Have the temp and humidity controller. Wont correct issue no matter what I do unless I run a de-humidifier, which I did run at the end of my last harvest. Im on week 2 flower and need to settle this right.
I'm with you. I live near the ocean in Massachusetts, the rh is probably similar. If you want to run a line off your central air, then that's more like a practical HVAC problem. But AC and forced air heat are both drier than the outside air. So that would do it. You could try creating a vapor barrier around the tent with plastic or whatever. It will hold in more of the warm air you're presumably venting into the garage. You could hang chemical dessicant bags inside the barrier to keep the air dry. You could try insulating the tent. It's probably the easiest thing to try, you just wrap sheets or blankets around it. The air will get warmer during lights on, and bleed off slower while they're out. A slower cooldown will lead to less condensation once the lights go out, I think.
But that doesnt get rid of the humidity which I think is the main problem preventing temps from rising. Just 1 month ago with 55° dry weather I had no problems getting temps above 80°. Last night I put the meanwell drivers back in the tent and still only got to 72° and it struggled to stay there. The night before high temp was 68°.
Whats the best placement for the fan? Up top or on the ground? Right now I have it on the bottom thinking its sucking out colder air. Maybe the top works better for humidity?
Anywhere. Home Depot. Walmart. Amazon. They've got a little smell to them, not bad, but like drier sheets. I aired `em out for a few days before I put them into the tent itself. But I don't think a little perfume will hurt the plants, and I know you're eager to put this problem in the rearview. Full disclosure, is all.
They dont work well imo especially if you're running any sort of ventilation and looking for a permanent solution. Theyll never be able to keep up with the incoming air. Those work better in small places like closets that have no ventilation. With ventilation and high humidity damp rid fills up very quickly. Youll end up spending more in the long run buying damp rid all the time. Ive been there. How high is your humidity? I grow in high humidity all the time without any issue, somerime 80-90%+. 60-70% is fairly average until winter when the humidity plumits. All thats necessary is fresh incoming air and a lot of circulation above and below the canopy. Plants actually like humidity. Strong extraction fan and fans above and below tour canopy and all will be fine. Happy growing bud
I had water dripping down the walls it was so humid. Have fans below and on top but the humidity is so high that water collects on leaves if I close the vents even with fans blowing directly on them. I had a couple a rotted nugs my last harvest because of it nothing major though. Probably gonna run duct from the main AC so that itll be fixed for good. Im a certified AC tech and was just wondering if anyone had tried it.
Ive been there buddy. When it hits 80-90% if i didn't have the right ventilation setup, water would be dripping too. Heres something you didn't think about when redirecting your home ac, it doesnt run 24/7. So as soon as the a/c gets your house to the desired temp it will stop pushing the drier air to your tent and the tents will begin pulling in the humid air and humidity will rise staight back up to the current % until the ac kicks on again. Thats not going to fix the issue. Youll need to bring down the humidity of the room the tent is in so that youre constantly pulling in drier air, not just the tent when the ac is running. Plus during that time temps will probably drop even further. Do you not have a hygrometer? Grab one if you dont. That way you can see what is actually working and what isnt. When i tried damp rid when water was accumulating on the walls it did barely anything at all and had to be replaced all the time. Your looking to grow for a long time right? If you're worried about humidity look for a pemenant solution, not a temporary fix.
I like the idea. Does the bathroom have a shower in it? It'll pump in a lot of humidity into your tent if you do. Another option would be to get a little 250W ceramic heater and a temperature controller. Ceramic heaters tend to dry out the air as they heat the room.
I did this and put in a temp controlled damper to have a little more control so u can tweak to be within a couple of degrees and % RH ur trying to achieve. I found that once I got the tent insulated to what the house is insulated at (r19 walls r30 roof) and seem to maintain the rh and temp within a couple degrees. Another option is to use a smart thermostat with a couple of wireless sensors and put one in the tent and a couple around the house. The thermostat will adjust accordingly.

I dont want to put anything else inside tent so Im going to run "6" duct with damper and tstat from somewhere other than the bathroom. My AC genius tells me this will work.
Have heaters and dehuey. Too expensive to run perpetual and not enough breaker power. Already burned a heater plug and extension chord. Trips breaker when shop vac is running with heater on. Garage is maxed out on amps. This is the reason why I want to run duct from the house free heat, free dehuey, free cold. Not really but you get the jest?
