Mitus - 4x 1000W // CO2 // Sealed Room // Hydro Drip

[Mitus]

WOO HOO AC baby!!
yeh some screw u on the copper hose for connecting the units and they can be expensive to install.. Eg. an installer will charge a standard price for installation which usually includes 5 meters of copper hose and elec wires THEN anything over 5 meters they charge at $100 per meter..

And to install them correctly mitus u need a vacuum pump to get the refrigerant through the hoses and get the pressure right, and for the unit to be signed off on otherwise the warranty will be void.. also they can only be installed by licenced dude bcos the industry is regulated bcos the refrigerant that runs thru the system is like toxic and Joe Schmo cant just go and pick some up from the local hardware..

That said, if ur fairly handy then u should be able to hook it up urself as jackmayoffer did, BUT the refrigerant wont be properly vacuumed which will/could result in ur machine not running to its full potential cooling/efficiency wise and also the unit not lasting as long as it otherwise would have..

Anyways this was alot to write so its a bit slapped together, i hope u make sense of it..
Im also on the split system hunt now as u know man..

As far as vacuuming the lines... This particular setup comes ready to hook up if you're fast... I'll have a 15 second window once I unplug the lines to connect them tightly or I may have to vacuum them. If thats the case, one of friend's dad has been doing A/C for about 20 years and offered to lend a hand if we get stuck. I'm confident that we'll have this thing done and have my room fully operational by tomorrow night!!

Wish me luck

So after lots of research I decided to ditch my former A/C & cooling method... I canceled my order for the Hydrogen 6" Ice Box and went out to purchase a new A/C unit that would meet my seal-room's needs.

I purchased an 18,000 BTU split A/C unit for roughly $1,000. I made sure to get one that runs off of 240V electricity so I can save my self a little juice. Tomorrow I'll begin the installation. I was a little upset to find out the unit did not include any wiring components... like the wires needed to connect the outside unit with the inside unit as well as a power cord or power supply... At least I thought the guy would of wanted to sell me one to squeeze some more money out of me haha... I'll keep you guys posted on the progress and here are a few pictures of the unit itself. I've already mounted the inside unit.

Once the A/C is done, all I have left to do is connect my res pump to the manifold and set up my res drain for when I do water changes.

Right on brother! Mini splits are the way to go when you're running that many lights, or more. What is going to happen with those Ice Boxes? Not planning to use those any more? If you do use them, you'll only have to use the mini-split system every so often, and it will be even more climatically controlled. Energywise though, running another chiller, using a remote res and pump, and running at least a 70W Can Fan on each end of every light will add up.

And for the rockwool nay sayers, hogwash. The Dutch and Aussies have been hydroponically farming with them forever, and with AWESOME results. So have I. IMO, aside from having to pre-treat it, it's the best substrate out there. I'm getting great results from the new UniSlabs, and years of using rockwool slabs. Now I'm experimenting with the 6" blocks versus UniSlabs, but I have a feeling the UniSlabs are going to win. We will see. My only advice is to get another res. By the looks of it, it's a 70 gallon? You'll need two of those, especially when you get into flowering. Those plants will be sucking up so much water, you won't be able to leave for even a couple days. Trust me, and good luck!

You really think I'll need more than 70? I was doing 36 smaller plants on a 30 gal res and changing it every 7-9 days. Now i'll be doing 36 larger plants and I think I'll be ok with 70... for at least 5-7 days.

Now you're making me nervous... lol

Looking nice Mitus, i believe everyone would love to have that much room to work with. Plenty of room to move around and get things done.

Are you going for a three week harvest, or are all the tables going to be on the same cycle, if i saw things right i believe all the tables are running off one res so i would think all tables to be harvested at once.

oh yea and the brown pads in the tables have not seen that before whats that ?

Yes I will be running all three tables on the same cycle and hopefully the plan is to have only 1 strain throughout the room.

The brown pads are Coco Mats. If the roots grow through the bottem of my containers they can go through that mat and it provides enough humidity under there for them to survive. Sometimes I'll pull up one of those mats and i have roots EVERYWHERE lol...

Very nice, going to make things a little easier with all one strain, and one harvest.

great idea on the coco mat !!!

Mitus,

Looks like you have a sweet setup, man. Looking forward to seeing some results when you get this room up and running... I am going to purchase a split A/C unit sometime soon, so you'll have to post some details on how difficult setup/wiring was, and ultimately how it works relative to the size of your room. Where did you purchase the split from? You thinking about expanding beyond 4x bulbs?

I also noticed your CAP CO2 monitor on the wall in your pic. I was curious how you feel about it? If you would recommend it? Also, wondering what kind of atmospheric monitor and burner your using in parallel w/ the CO2 monitor. I'm currently looking for a nice setup. Thanks in advance for the input.

The A/C came with semi-decent installation instructions. I picked up some #12 wire and some #12 romex and just followed the instructions on what to connect to what. Then hardwired the outside unit into a double pole 20A breaker in my subpanel.

The hardest part was pressurizing the lines after it was set up. Luckily one of my buddies has done A/C for the last 20 years. He lent me some stuff and walked me through it over the phone. Not the easiest task I've tackled yet... and wouldnt have got it done without a little help from my friends...

I'm doing my first test run to see if the unit can properlly cool the room with all four lights on. Took me a while to figure out how to stop the A/C from turning off every 10 minutes lol...

I was told that it may not run at its full strength the first night? or something of that nature... anyone know if there is any truth to that?

Here is a few shots of the gauges used to pressurize lines

[razoredge]

man sure you put a proper charge in it?? if it is starting and stoping often it is called short cycling.. not good

 

[Mitus]

Yes, I'm sure it has proper power. The reason it was stopping is because I didnt know how to use the remote yet. i had it in the wrong "mode"... its been going at it for a bit now with no inturruptions

-Mitus

 

[Mitus]

Well I was wrong because it just shut off again. I doubled checked the unit and it says "Minimum Fuse 15A" and "Max 22A"... I'm using a 20A, that should be good enough...

 

[Mitus]

What do you mean by proper power charge?

 

[Mitus]

Ok, so upon reading through the manual I cam across a feature the unit has called "the fault protector device..." and it may shut down the unit for the following reasons :
1) stopping the unit and immediately restarting it or changing modes without waiting 3 minutes for time delay
2)plugging the unit into the power source and immediately starting without 20 seconds time delay

Then it says :
If all operations have stopped due to the fault protector, press "On/Off" button to reset the unit. Then set timer again if it has been cancelled.

I dont know what all these rules are about but I'm not sure if I should keep trying to run the thing or wait till tomorrow and have some one take a look at it?

Yes, I absolutely know you're going to need another one. You'll be fine for a little while, but into flowering, you're going to need another one for sure. My setup uses only two lights, (although they're on an LR5 and I'm using 3' X 6' trays) and you're going with twice that, and Co2. Don't sell yourself short. You haven't so far, and you'll save yourself a huge hassle later.

 

[IgrowBIGG]

I didn't read through all of this but if u have a timer connected to your power source that keeps shutting off then listen to the manuel and just set your timer to have at least a three minute delay between when it turns off and the next time that it turns on. If that doesnt apply to your problem than foget me lol.

 

[streetlegal]

mitus bud, sorry to hear of ur problems..
so u needed to vac the lines yeh? and did ur buddy give u the freon.. this is starting to scare me off the split..
wonder how window ac goes with co2..
anyways ill keep checking in.. ull get on top of it bud, dont despair

 

[Mitus]

Ya, its no easy task bro. The only way I'm getting by is my friend's dad has been doing A/C for a long time and loaned us the stuff to Vac the lines and fill freon.

Looks like we didnt put in enough freon though, so we're going to have to re-vac and fill freon tomorrow.

 

[razoredge]

thats why I asked you if you had the proper charge as in refer charge.. I am a HVAC tech, I can walk you through it.. make sure to purge the gauges every time you hook up to it.. if you contaminate it with air or other refer you will have mixed pressures and cause a early failure.. i am here bro.. PM me

Ok awesome bro. My buddy should be here with the gear and freon, mid-day tomorrow, so if we hit a snag I'll hit you up.

[Mitus]

Well I can say I just shed a few tears of joy... After re-doing the freon today, I've ran the room with A/C for about 4 hours and am able to fully control the temperature. And can have it as low as 65 degrees with all 4 lights running. gotta patch a few holes and what not tomorrow... but its going to be an eventful weekend... THANK YOU TO ALL THAT HELPED
