Hey guys, I'm gettin ready to wrap up my first grow here in the next couple days or so. Anyway I wanted to make some changes to my grow room, make it more effcient. This is what I was thinking, there's a pic of my intake which is on the floor and it's just a hole through my floor bringing in cool fresh air, this is a problem atm because it makes my room too cold at night. Anyway I was gonna install an electric damper in that hole so that it is normally closed to keep heat in better, when turned on it opens up allowing fresh air in. My next plan of attack was to seperate my room ventilation from my light cooling, I'll be buying a 4inch inline fan rated at 171cfm to keep the light cool, also use my fan controller on it so I can use the light to stabalize my temps during the day. There's another pic below where my ducting comes out from the attic, I was gonna hang my carbon filter there which will be hooked up to my 6in inline fan at 435cfm to clear the room. my room is only like 58 cubic feet or somethin like that I forgot, it's not even a room it's my closet. *breathe* Now, I want to hook up the electric damper and the 6in inline fan to the CAP adjustable recycle timer or the Sentinel Digital recycle timer haven't decided yet, set to a time of on for 5-10min off for 20-30min. So every 20 or so minutes the fan turns on and the damper opens up, removing the stale/smelly air and bringing in fresh clean air, than the damper closes and the cycle repeats itself. The next item I wanted to put on my list was a night time device like a small small so small heater with a thermostat to turn on when the temps fall below what I set it at or however they work, still shoppin around for a heater. Could this pose as a fire hazard in such a small space? Is there other means to keeping the closet in my temp zone at night? I have a few questions first though, Will my fan not like being on the recycle timer, always turning on and off? And how many items can the CAP adjustable timer use per timer, Will I be okay hooking my fan and damper to it? Or would I have to buy seperate timers for that? I've never seen a grow room run off of recycle timers so I'm unsure. The only reason I don't want to use a atmosphereic controller is because I'm not running co2 and I'd rather get something like the CHHC-1 later on, instead of blow money now on a unit that won't serve me as well later down the road. Where as the recycle timer I can use for a lot of things down the road.
I suppose your electrical damper plan will work. But, can't you just adjust your room fan controller down far enough to not bring in too much cool air and have a small space heater as a backup? Seems over-complicated and a PITA to setup a timer on-off cycle connected to a fan and damper. By the time you get it dialed in, it'll be summertime lol. I used a small $12 space heater from Target with built-in thermostat and it worked great. When it got below about 70 deg., it would kick on for about 30 seconds every 10 minutes or so to keep my space warm - and no it's not a fire hazard. Since switching out my 400 MH for the 600 HPS, I don't need the heater anymore. Keep it simple, bro.
Okay..thanks man, I figured I was over-thinkin that, it never made complete sense. Alright well, imma go get me a heater and fix my cold problem
Hey, another thought. You're cooling your lights, right? So was I. When it started to get cold this winter, I took the ducting and glass off my hood because, well, why do I have a space heater and air-cooled lights? Didn't make a lot of sense! LOL. Now I'm using the heat from the light to keep the space warm and, like I said, I don't need the space heater anymore. Just a thought. Good luck bro!
Before I decided to seal my room and use co2 I just had a carbon filter and 8 inch vortex inline fan in the room hooked up to a thermostat that was by passed by a dimmer switch so you could set it the dimmer to a very low constant and the thermostat to 86 degrees F. Constant low negative pressure and the fan vents hot air when the temps peak.
Yeah I thought about that, but my problem is heating the room at night, I don't have any issues during the day when the lights are on, the fan controller is set pretty low right now so the room heats up to about 77-79 degrees. At night it gets hella cold, Anyway I bought this heater today at walmart for 35 bucks but it's a hell of alot bigger than I thought, but it's really hard to find a really small digital one.
