So the unit is 10”x40”? I have like no where on my walls to put that I just measured the only place is like 8’ from the wall Id put the hole and outdoor unit.

Id have to remove the tv or put it over my head where I sleep and it may cause an acoustic effect to that room on the other side.

Would be doing it just for a few hours each morning just for summer so I guess thats an example of why hvac guy didnt entertain that idea and agreed with basement grow. Not to be lazy probably because it made the most sense.

Im slowly moving myself out of my room lol not the tv!! About to remove the stand below it and leave it wall mounted for more grow space. So Id lose my tv unless other option.

Thats crazy I just realized even if I wanted to grow in basement, I done made more flower square footage than I can make downstairs ATM with my allowed space which I do need for the pressing.

Im working on 34 square ft flower space where downstairs Id only have 20, no more reasonable space left for a tent bigger than a 2x2.

So Im using half that space to press which is really needed, then a 3x5x6 veg tent and its reservoirs which is what opens more flower space in my room.

I just didnt know how to maximize my situation until now, now that Im getting intermediate with my grow skills. Heck I was genuinely doubted I could get 16oz in the 2.5x5, I got 14 last run and 12 first try.

Thats why I like when they say mileage varies everyone is on their own journey lol.




Oh wow Ive seem those, idk how well they perform but that would probably be what would have to be used in my bedroom. Curious how it works, Id think a refrigerant line would go to the indoor unit somehow. Is it through the tubing?

Installing it would take professional help for sure, idk where the hole in the indoor/outdoor wall would go. Like I just got done rambling, it may be worth it.

I just ran 2 of those in my grow rooms. I have 2 more slated for later (it's too hot now to do much in my attic). Here's a single zone of the Mr.Cool 27k 3 zone I installed

You have a compressor fan with the refrigerant outside on the wall. You run your refrigerant, suction and condensate lines from the outdoor compressor to the indoor units. It's a fiddly install you might need some help with but if you can do a little electrical and basic dry wall work you should be golden. It's changed my grow 100%

This is the wall cassette I have in my multi room it's 18k and cools all the grows in the lung room. But I hate the form factor on the wall.

So in my flower room I went with a ceiling cassette so as not to have to mount the humback whale above, on my wall.

Both are running right now and the only way I know is the swinging louvers. Otherwise it is completely silent in the room.

I'm in the Mojave Desert. So usually the summer was ark mode for me where I just muddled through. I grew through the installs but I'd have been smarter and quicker to stop. So I think you're on the right track.

I in fact am pretty sure the hvac guys that were here can help answer any questions and install it, dry walling and etc is part of what they do aint it? I know they dont just hire someone to do the structural work aside with them but possible.

But yea itll only get a little hotter using hotter lights but these buds just speak for themselves. Cant imagine using even better lights.

For 3 months, fall winter and spring its cool enough to use outside air. The hottest its gotten this season is like 92F if any hotter its a heat wave and making records.

When making my workshop I wonder if its better a closed system or both venting out and cooling. I think same thing would apply and it would be a closed system.

Probably one or two of those mini split things. I wonder how people do theirs in a workshop.

Ventilation. I think if you will struggle to fit a 6” fan and filter in the tent, then a 4” is good. I just came up with that, is it right?

My 3x3x6 barely fits a 4”. That mean its probably enough for a flower tent? It wont move much air but fitting a 6” would be too hard, its already going to take from the light space/shine.

My 2.5x5 that are 6.5’ tall fit 6” easy and feels right. Its crazy that theyre almost the same square footage so Im not so sure.

Im thinking I can put 6” fan on top of tent and only the filter take space inside. I dont want to skimp on anything Im actually setting myself back but for sake of upgrading to have all optimal tents.

Im gonna get a viparspectra for this 3x3 tent.

really depends what sort of space you have to work with, and making best use of that space, I'm currently in a tent and set up pretty much like this..

I know I have negative pressure in the tent, as the extractor fan sucks the sides of the tent in slightly when it's zipped up...

I worry about mold in attic doing that but I dont usually see people vent the attic out. Yea I have 3 large tents with whats going to be large fans moving a shit ton of air.

I originally exausted outside like the title said but if you check out the last few pages that turned into a disaster with hvac guys. It ultimatly having to be back square one again.

That setup would be nice in the sense they kept saying more air has to come from somewhere. But it wouldnt really help if whole house is warming up.

They tried to work with me but just decided my grow was the problem. Still has a huge impact but its barely keeping up to put the problem to rest.

Lights on time set to sleep hours helps, almost solves the issue. When the ac kicks on close to noon thats when it heats up 86F but down to 78-80F when ac is on all day.

I just got done getting geeked that thats pretty much my solution I can still live with. The ac is a closed system that keeps absorbing heat energy and so when you vent out it has to start over again.

Thats just my words but its what they said I just didnt hear the convo. I was otherwise 100% involved because it was me causing the problem.

Im hoping to re do the exaust outside setup in preperatuon for power outage in summer. Itll get too hot with no ac so I want to still keep the setup and have filters inside tent.

If you are growing a lot then wet air in the loft might be an issue, but I dunno how your loft is designed... mine has gaps around the eves for natural ventilation, as they shoulnt be 'sealed' as such.

In terms of extractor fans, i realy rate EC style fans, they are super small, efficient and powerfull...I dunno if you have them where you live but I'm sold on my 'mammouth 'juiced' EC fan... the 6" version is basicaly no bigger than the 6" ducting, has in included speed corntrol dial...and the way they work means if you dial it down to 50% power, it will just pretty much 50% less electricity unlike conventional fans.

The freakin guy all agitated moving a generator in rain I was like damn they knew exactly what to target sales wise. I really pretty much picture that happening when I finally use it.

Just got done buying concrete step stones to lay on ground for the generator. Gas cans since mine are nasty as hell. Will fill them up and dump every 6 months.

edit I had a place to set it but its too close to neighbors house and window. Hoping centering it in back yard will minimize impact on noise and ventilation.

Just trying to get prepared! Il love it when I get used to it. Be the only one with power in the neighborhood, thats fancy!

Theres few others that must have one cause I used to hear them every outage and still do.

I used to think it was worker trucks near by but since I looked into generators its the only explanation.

You could still get a transfer switch and setup portable generators to auto start just like the standby types do when the power go's out.

$$$.. :eek:

Its also possible to mod the exhaust systems and add a muffler, to help quiet it down a bit.

Holy cow I hope mine isnt that loud. Glad I spent time figuring out how to center it in the backyard. Dont want to piss off neighbors.

edit I found a good video demonstrating, its not bad. Maybe cause hes in a garage.
