air conditioning

looking at 24k btu mini splits to cool a 12x15 flower room running 6000ish watts of led+cmh, I have narrowed it down to a couple of choices, either THIS 21 seer wall mount unit by Aircon, or THIS 20.5/21.5 seer unit from cooper & hunter. Looks like they both use the same CMGG Toshiba compressor...

What up y’all my a/c just took a dump and now I need another one so I’ve been looking around and there’s so many options available. But before I get one I wanted to see what the rollitup community has to say about it any recommendations?? Need a reliable 14,000 btu air conditioner!

Once again I am asking for your grower knowledge as Im currently running out of ideas so please bear with me. Thanks to this forum my current ongoing Autoflower is absolutely flourishing but as the title suggests that's not why Im here today. Aforementioned Auto is 3 weeks away from harvest and...

My AC unit (traditional split unit) takes too long sometimes to cycle on. The Honeywell thermostat will flash "Cool On" for 3 or 4 minutes before turning on solid and the compressor and fan actually fire up. This is a time delay to protect the compressor I believe. This is creating large temp...

I have a 4x4 tent that I started to grow in and during the summer the temps were/are so high that even with a portable a/c venting in, I cannot get my tent to the below 80 degrees recommended for bloom. Instead temps range from 85-90. Not to mention the A/c runs constantly. Yes I added an...

i am building a grow box. for a 4 plant SOG personal use strictly under 2 600watt bulbs. probably will get the yield and will only have to do a cycle once every year or 2. I am really health conscious i work alot and like to train and keep fit this is the only way to know im not getting poisoned...

Hey, I live in a very hot part of the world. Direct sunlight comes at a cost of 38°C (2PM - 5PM) After 10AM temps cross 30°C and don't drop to below that till 9PM. I've been giving the plants direct sunlight till about 1PM (35°C) and misting them. Then moving them inside with air conditioning...

Hi all! First of all sorry for the long post, but my grow setup/situation is a little unusual I think so it requires an explanation. My conditions: I grow inside a small grow tent (80x80cm/2,5x2,5 feet), which is inside a spare bathroom that I repurposed for growing only. The bathroom is pretty...

What's up guys, So I'm finishing up a new 5x5 tent setup, so far I have all my bases covered equipment wise - I just have this possible option nagging me in the back of my mind. Long story short I live in a hot, humid fucking climate - this week in October temps ranged high 80s - 90 day, mid...

Hi guys n gals I'm after advice on portable air conditioners, sadly in my part world we can only get the one hose types, I've heard of people who have modify them to be dual hose , anyone tried this also advise on BTU's for 420 cft are under 2x uncooled 600hps

Hail Friends, I live in a tropical country where part of the year the temperatures get into the high 90's F and the humidity can reach 85%. The natives grow outdoors, it is sadly not an option for me. Therefore I am doing an indoor stealth 'closet' grow in a big wooden wardrobe. The grow...

First time set up, pardon my ignorance. ;) SETUP: I have a 9' wide, 12.5' L, 8.5' H flower room. It's in a fairly cold portion of my house and I live in the northern western Oregon region. Winter extremes, high's in the 30's low's in the 20's. Summer extremes, high's in the 90's at times...

Hey guys, I'm looking for people who have experience with having lights without air-cooled hoods AND without them. How big of a difference do air cooled hoods make for overall temperature of the room? Is it nominal or significant?

I'm planning on setting up 3 4'x9'x9' rooms. Each next to eachother on their long sides. I want the rooms a little bit bigger than the light footprint to give me some elbow room to work with hence the room sizes. 2 rooms will have 2 315 sun system lec each with Co2 alternating veg/flower...

Stumbled over this little thing. A bit pricey with about 150-200 bucks, but it might be a godsend for smaller grow ops, tents and boxes that struggle with heat. Evapolar - First personal portable Air Cooler here their kickstarter video (has been funded a while back and is available to buy on...

I mocked this up quickly as I feel so far it's my best layout idea for the space I have to work in, the whole thing is about 10' x 13' w/ some addition utility space toward the upper right corner that doesn't count as growing space so it's not shown (where passive intake is) I'm trying to avoid...

Hey y'all got my second post going here and need some help on setting up the correct equipment before buying. So I'm growing for medical purposes and can only flower 4 plants at a time. That being said I'm going to start out with a 4x4 grow tent going scrog. And thinking of running 1000w or...

Hey guys. I'm new to growing and have setup my room with a 4x4 Veg tent with 600w MH and a grow tent with 2 1000w HPS bulbs. Everything is vented to the attic through 8" hoods. I also have a 8" blower scrubbing my grow tent. My temps in the bloom tent are mid 80s. What size portable air...

The only reason I built a RCWC system is because i believed I needed 13 gallons of nutes to run a chiller (I didn't even know what RDWC was when I was building this thing I should have looked up more before starting hydro). Anyways that is not true, it's very FALSE and this can save you a...

So I picked this a/c unit up at an auction a few days ago $40, runs great, not loud, even has a dehumidifier setting, I plan to use it in a detached garage grow, I have a lot more head space in there, my only problem was lack of cooling. Then I got this thing, it has a vent on the rear to expel...
