It's cheaper to buy separate a/c and dehuey units than combining them.
Thanks for the advice.
Building a very small mother room, about 152 sqft. Plan to run non-aircooled 2x400's or 2x600'sdepending on what I am working on. The room will prob have a small 25pint/day dehuey
Thinking about slapping a 9k btu, smallest mr slim they make, in there for temp control. Crazy?
It gets sub zero in Michigan. i am trying to go totally sealed room to have total control over the enviroment. But its getting complicated and almost seems like a waste of resources. Excel Air says with there low ambient kit there system will cool in -20 degree weather. Im trying to find other less costly options. I know one option would be non sealed room in the winter and sealed in the summer. But if there was a way to keep it sealed year round, that would be my first choice.
Cover the outside w a rigid foam cover and make sure to take it off if it gets over 30-35Is there any way to keep a window banger from freezing up in the winter time?
I don't know how us cold climate guys can use sub zero air a couple months out of the year for cooling purposes, unless it is conditioned in a lung room before introduced into the flower.
Maybe CJ could chime in more on this-
Not a whole lot on lung room/cold climate growing info here on the farm. Found some good info on IC that "dun haven' fun" posted, but he was in a warm climate. I'm thinking about using a lung room as a "perfect climate room" that will pull cold outside air (most of the year up here) in if necessary- both flower rooms will circulate air with the lung room, so one of them will be discharging hot air into the lung to balance the climate.
I don't know how us cold climate guys can use sub zero air a couple months out of the year for cooling purposes, unless it is conditioned in a lung room before introduced into the flower. At the same time, these mini split condenser units will not work at -20/-30 degrees in our winters. During the warmer months, the lung room could be closed off and ac used to cool. But like tbone said, if it were practical to stay sealed year round, it would be much easier...
Hello Farmers,
I just joined so I could post on this most informative and helpful thread. Thanks Cannabis John for holding it down for so long. I'm finally building my own growroom after years of "assisting" at other people's ops. It's a converted bedroom 10.5x9 (flower with 2 600s now, 2 more later) plus a 2x4 closet space (veg, recirculates flower air). Inland NorCal so 90s-100s for a long part of the year. Room shares one wall with garage and I can DIY as needed. Water for washing machine is on that shared wall (thought about chiller/ice boxes). Remote ballasts will be in the garage.
This will be a long-term arrangement and I may expand with a tent or two in the garage if all goes well. I planned to use bare bulbs and fluoros in the bedroom to start, so no hoods to vent the heat out. Using a Sentinel CHH4 to control environment. So I'm at 3000 watts of lighting in the room with a potential for another 1200 in the garage (may only use for a cycle or two during cooler months). I was thinking a 2-ton window or wall unit to save $ upfront, then upgrade to a split (LG, Fujitsu, or Samsung, right?) after a few cycles.
Does this sound like a good plan? Is supplemental CO2 generally necessary when using window/wall unit? Skip the window/wall unit and do the split right away? If w/w unit okay, what brand/size/retailer suggested?
Thanks and again... I'm happy to have found this thread and all the unmentioned contributors. Is this thing a sticky yet?

Thanks CJ for that response. I anticipated that answer. Since its early December, and cold enough now, I'm going to run the room vented for a cycle or two. Air is cold enough to pull from outside and pass thru the room to the scrubber which exhausts into garage.
On linesets... I'm seeing folks talk about min/max lineset lengths. Best to position outdoor part of split so that once uncoiled, the linesets length reaches the point where I want to install inside part of the split?
Current recommendation for brand and online retailer would be awesome so I can research more over next few months.
Thanks again CJ!
John you used to rep those daikin pretty well , something change your mind?
