20 1000W nanolux DE setup questions??

[highcountrygrow]

Just got 20 x 1000W Nanolux de ballasts to replace my 9 and 6 kW rooms. I was thinking about setting it up as two 10 light rooms (run one during day and the other during night) in order to keep heat down and i am also limited by 100A for the space. Here is some more info about the space I'm trying to set up.

dimensions
length 50' x width 15' x height 10'

power
100A

how big of an A/C should I set up if Im trying to have sealed rooms?
What is the most efficient way to set this all up? to keep everything under 100A with A/C and atlas 10 lights on. Would very much appreciate any input on this one! Trying to make sure i set it up properly now so i have no problems later. thanks IC members

I'm not sure about DEs but ya typically need a 5 ton AC for every 15 uncooled lights. 12 lights is what I've heard is a good number of DEs on a 5 ton. This is assuming you are in a well insulated space.

So..

Do 2 -10 light rooms. A 5 ton per room, or get fancy and get a damper package to flop the AC over to the other room. Either way I think you're falling a bit short as you cannot run this way 24/7. You only want to run at around 80% capacity when running full demand like that. I don't think you can do what you are trying to do on 75-80a.

12,000w / 240v = 50a. You've got about a 50a draw out of 10 DEs at 240v. (the Nanos run at 1200w max setting). You probably want a 70a or 80a feed on your light controller alone. Your 5 ton AC typically needs to be on a 50a breaker.

Even if you run this on a 10 light staggered schedule I'm still not sure you've got enough juice to do what your trying to do safely. Especially with anything else needed to get the job done.

You're best bet is to possibly get a service upgrade to 200a. Or if your in a cold enough climate try to do it with exhaust fans and cold air intakes to eliminate the need for AC's power requirements..

Shouldn't you be running thirty lights in a space that size?

Each nano gets a 5x5 footprint, as they were designed, and you evenly light the whole room

Have heard.4k btu per de. I doubt you're pulling that off with 100 amp unless you're using ventilation.

I'm barely managing 16k + 3k veg plus dehueys, fans and ac on 200 amp

Thanks for your response. I do have the ability to pull a line for more power for the A/Cs from another building, which sounds like what I'm gonna have to do. Then it would just be 10 de running with wall fans and a couple larger inline fans to recirculate air between the two 10 light rooms and some pumps for the automated watering system.
Talked with a couple A/C guys and they told me i probably needed two 3 ton A/Cs to cool that space efficiently... does that sound about right? 70,000 cooling btu's

I am only using two 250q foot rooms out of the 750 sq ft available in the room. Again i am limited by only having 150A in the building where the room is and 100A line for the lights and fans. (the other 50A is being used for a water heater)

250sq/f. So 10' x 25'? Yea you're right ten would be perfect for that..

What about night time cooling?

Also a single 5 ton would absolutely cool ten lights. Even overkill perhaps .. a half a ton per light is alot. I've read a gavita rep here on the boards say 4k btu of cooling per 1kw lamp. I assume the nanos are similar..

yea 10 x 25 per room. 10 light per room. one room on during day and they other at night. w/ 2 x 3 ton mini splits? maybe that is a little over kill but i don't want to push one 5 ton A/C 24/7. It would put a lot of stress it

 

[shredGnar]

I promise a 5 ton would easily cool ten lights and all the gizmos.

I run ten hortilix in a 20 x 10 and my 5 ton rheem is perhaps over kill. Cools it down minutes...I think it's great, though. The argument against over sizing is you lose out on the dehumidifier action if the a/c. I like to run higher rh so that's actually a plus for me..

Anyhow man are you saying 1 three ton in each room?

It would be pimp if you had the 5 ton with electric dampers, take care of the day time cooling. Then a small mini split in each room for night time cooling..

after much deliberation i think we are going with one 3 ton 2 zone(for each 10kW room).... we live above 9000' in the rocky mountains so it rarely ever gets above 80 mid summer. in the winter it can get very cold which i understand can ice-up mini splits. anyone have this issue in a cold climate? if so i was thinking about just putting an intake from outside during winter if the A/C won't work for the sealed rooms. So it would run unsealed for about 3 months out of the year. I feel like A/C is a bit overkill/wasteful if I am living in such a dramatically cooler climate , but i want to reap the benefits of the sealed room with DEs to help keep the co2 from being wasted or diluted by a fresh air intake.

I live in the Rockies as well..

I have had my air handler freeze up once when it was minus thirty this winter..

What I did was built a shed type structure, which holds in some of the heat. I have a few different openings to adjust how much fresh cold air is allowed to enter. It also keeps the snow of it.

I hear you on being wasteful/frivolous running an ac when it is negative degrees outside, however it is worth it in my experience. Nothing has improved my yields like a fully sealed room where all aspects of the grow can be manipulated.

I was considering the excel air stealth at one point. The compressor is separate from the outside unit. They claim your can run it in -30 no problems.

Super expensive though, and have heard people talk shit about that company

we are going to build the sheds around them to protect them from snow and help keep some heat in during winter.

I am excited to finally make this move to the de sealed room... I've been trying to make it happen for the last year and now finally have the capital to make it happen. Although it is an expensive endeavor and things will be tight for a few months i know it will pay off ten-fold. Its just a stressful transitioning period as I'm sure many know.

Yea i hear you on the excel systems. we are going with two 2 ton mitsubishi A/Cs

Man I use 5kbtu per 1kw. Works good. With Gavitas. With de hues and etc it works good. Leaves room for August heat. I'm lower than 9000' though. I wouldn't even use ac that high up.

Ur location n budget is the desiding factor... the half ton per light is golden eveywhere... give u enough incase it gets hot .. here 3 ton barely cools 8k unvented... but if ur at 9000ft never above 80 u could def GET AWAY with less but the larger unit would be well worth it... it's not oversized to were its inefficient and u would have more control. ...n the ability to add a few more lights if ya want...
