Heres update on the girls that are currently in the room. I think the heat made a few of them really stretch super tall but it could be the strain because both plants of that strain are pushing 7 ft tall. They were switched 16 days ago and feel like my last cycle i didnt see so many bud sites so early.

You also might want to grab a WIFI controller for your AC unit. Pebble, Sensibo are a few. This would allow you to schedule the AC to come on and cool when the lights are on and it could switch over to dehumidification mode if need be when the lights are out. You can also view temperature and change settings from your phone.
Will look into them, originally starting out last year would have never imagined spending what i have on the grow operation lol.

Mitsubishi
So i reached out to a mitsubishi rep to go about getting unit, since set up is in my garage i converted, the dealer said he wouldnt be able to unless i get a permit for room conversion. Any other options for obtaining a unit with all the accessories need to install myself? Obviously a little under code here lol

Maybe just convert the room with a permit the right way if you want an authorized installer to put the unit in. This would mean you get a factory warranty on the parts for a long time.

You don't have to have an authorized company install it but it can help alot and typically these companies do it right.

Another good brand to take a look at is fujitsu. They may not be as good as mitsubishi but they have good technical support and are very similar

Hey Renfro those Mitsubishi do look like they would be best but man oh man they are pricey, let me ask you this I have 4 1000 watt HPS one of which is a Gavita giving off a lot of heat, and the ballast are in the grow room what size unit would you shoot for. 18kBTU or 24kBTU I am in Northern Cal so winters and nights are easy going, however Summer where I am gets hot.
I bought a Chinese made Gree brand Mini-Split and it leaks from the outdoor unit. I thought that it was the lines that I installed, but it's not, it looks like it is coming from the compressor. So, I have to charge my 24k BTU Gree 2x a year. I also have a Mitsubishi Mr. Slim 24k that I put on my house and I NEVER had to do any maintenance to it. Mitsubishi designed the mini-split and China just tries to Copy and Paste but with inferior materials. Japanese are known for great craftsmanship and it shows in their products. I don't hesitate to buy Japanese made over Chinese made. Mitsubishi is WORTH the extra money because it won't break on you...

Where are you located? If you are in Colorado I could help you get it installed as I have the tools to do it right.

I am in Northern Cal, mitsubishi will be the one i get as long as the one on the whole sale site comes with all the equipment needed to install. On that site it has the accessories separate as if u gotta buy everything piece by piece.

Def go with 6k btu per light, I chose a cheaper brand ,Mr. Cool, so I could install it myself. And if I run my lights on over drive it struggles to keep up when hot outside. Granted that's like an extra 900 watts total between my lights but it should keep up a lil better imo.

My point being a 1000 watt de light ran on overdrive needs every bit of 6k btu, atleast on off brand units.

Equipment needed for a very basic install would be a vacuum pump, gauge manifold, hoses, 5/16" port adapter, probably an allen head wrench to release the charge after youve pulled the vacuum and let it sit overnite to make sure it's not leaking. A flare nut torque wrench and nylog is also something you will want.

May need a flaring tool in case the factory flares on the line set are damaged or just not perfect (I always make my own flares regardless).

If you want to really make sure there are no leaks you need a cylinder of nitrogen and a regulator. This allows you to pressure test the lineset (pushes fittings apart instead of pulling them together as with a vacuum).

You will need to run power and set a disconnect outside to run a whip from to the condenser unit. Will also need a properly rated cable that goes from the condenser to the evaporator (control and power for indoor unit) usually they require #14 wire but consult the installation manual.

or, you could buy a cheap one, do a poor man's purge, run it till it dies, buy a new one and still not have spent the money you will on a mitsu. :D :bigjoint:

for grow rooms, the cheaper route is usually better because it really takes a pro to install one correctly. hardest thing to do is to run the 230v power supply

Downside to that is lost crops when AC units die mid flower. Also if you are paying for installation that will get costly.

I would always advise the more expensive route, one and done, reliability. I made the mistake of being too budget conscious thinking hey, how much of a difference can it be. I really wish I had went with Mitsubishi units over the Midea ones. Won't be making that mistake again.

I was trying to be funny, why I said it takes a pro to install correctly and used :D :bigjoint: these.:blsmoke:

end of story its better to get someone that's been installing units for a long time.
Yeah, mostly because there is a lot of expense in tools to do it correctly. There are plenty of youtube videos that people can learn the methods from, but the tools aren't cheap.

One thing about minis is you typically can't add charge to a gauge number as you can with other systems (non inverter compressor). So if you get into a low charge situation then you have to pump down the unit reclaiming the refrigerant (weigh out the old charge) and then weigh in a full charge with a liquid low side charging adapter. So you end up needing the refrigerant scales of course but you also need the reclamation pump and a reclaim cylinder. lol

One of the biggest mistakes by novice installers is actually over torquing the flares, galling and crushing the flare and causing a microscopic leak. Having a reliable flare nut torque wrench is a good investment.

There are a lot of little things though that you won't know until you have done it a lot, like calculating extra charge for a longer line set and whatnot.

Unless you are servicing several units for a money making enterprise then it generally doesn't pay to invest in all those tools just to have them collecting dust. If you do have the tools and the skills then you can fix a problem as soon as you find it, saving a crop and money. Sucks to wait for a trusted tech and these things have a way of breaking after hours on friday's lol. It has saved me more than once, and now I can rest easy that if my AC unit craps out in cold December I can fix it myself instead of getting odd looks and 20 questions.

I got the general idea been watching some people that fixup units more on the commercial side really does interest me. was thinking about getting into it would be not a horrible idea. bongsmilie a lot of problems on the commercial side is usually caused by a person that installed it incorrectly or half assed.

the one thing I learned atleast was look at the big picture don't just half ass your job. and oem parts are really amazing.
