10kw medical dream room (design+build)

[onthaherb]

Hey all -- I'd like the hiveminds thoughts and have a few questions on what my 10kw dream bloom room would look like.

The garage in question is 19x18 detached garage. 99plants scrog coco, 8 per light (drawing only shows 4) on 8x4 tables fed drain to waste.

There is only a 20amp breaker going to the garage overhead from a 100amp main.

I would do a 60amp upgrade, should I install a panel with a 50amp and 10amp breaker? I'd put this on the 50 and leave the 10 for an a/c -- is that realistic? Keep in mind I would still have the original 20amp for the scrubbers/vented hoods.

What kind cooling would be needed in combination with the A/C (never used an A/c in any grow before)? Would a 10" Qmax with Can150 do or would I need two sets? Also, what dehumidifier is suggested for this kind of setup?

For the Bloom Room alone you will need 100+ amps. Each 1k light uses 9.5 amps then add 20% for safety. You will need 120 amps just to run the bloom room.
Do you know what it costs to upgrade your service? It's pretty expensive and not worth it if you are simply adding 60amps. I wouldn't do it.
I also wouldn't grow in a detached building, its a basic guideline.

Where are you vegging at? If you are vegging in the garage then where is the needed power coming from?

I would say start small with 1-2k and work your way up.
It's much harder work then it looks.

Thanks for that but from my understanding running a 1000w ballast on 240v uses around 4.5amps and I will be vegging on the same tables.

You will need at least 45 amps for the lights and you will need at least another 20-30amps(most likely 30) for AC if you're going 240v there as well for minisplits.

That does not include fans, pumps, scrubbers,recirculating etc that run at 120v.

I don't believe your numbers are realistic. The last think you want is breakers tripping and lights coming in and out. Electricity is A big deal. Don't short change there or you will pay the price.

This is all just for bloom.

 

[onthaherb]

Not that worried about the limitations of the electricity, if need be I will run one tray less. Really looking for tips from anyone who has done something similar.

How do you get 99 plants? 59 in veg? What are your goals- yield wise? Is this a perpetual or is everything on the same schedule? If you're going to do the work of scrogging, maybe you can run fewer plants and lights? Check out aeroguerillas 18k medical grow... He does like 1-2 plants per 2k in tents if i remember correctly. You can start with single 1ks in your tents, and 10 plants, before you jump in on 40, or 99 or whatever plants.
I'm not trying to rain on your parade, this is an ambitious set up, it just seems like you might be underestimating the time/work/money.
I don't run coco, or setups that large, so take my criticisms with a grain of salt. But keep in mind efficiency.

 

[onthaherb]

8 plants a light is 80 plants, and there would be 15 or so mothers keeping us well under what our recommendation allows. There are no goals yield wise? I think if we got 3 harvests a year @ 1#/light it would be more than enough for our personal needs. Barebulb isn't that attractive of an option in my hot area and trays on casters make life easy --- although I have read through Aero's thread several times for inspiration.

Gotcha, sorry if I was harsh off the bat, you're drawing only has 4 plants per light? 8 per table...40 total. Not having run something like this, I guess I just wonder if its efficient to build tables and all that if you are running SCROG trees? That seems more like a sog set up...and a good one at that. For Scrogged trees why not go dwc/RDWC ? Or heath style tubs?
You smoke 30lbs of weed in a year? I'm sorry, I just cannot believe that. I can throw down a lb or two in a year, but you should be able to keep ten smokers very happy for a year...

If you are married to the table idea, why not go 20 plants a table with no veg?

 

[onthaherb]

No worries, valid concerns and I wasn't clear

I don't smoke nearly 30 but it's we not me! I like DWC but at this scale I feel like would be a pain. We may eventually switch to trees but it would just take too long to get to the first pull.

The idea is to stay in within our limit and veg as little as possible. We are somewhat married in that we already quality have trays & dripper to use.

 

[self]

It's making more sense to me all the time... It looks like you know what you're doing. I'm a Scrogger myself, so I'd probably go the same way to be safe, but depending on strain you may or may not need it?
I guess you'd be using it more as a support system rather than actively training into it during veg?
Right on, I think I've got it figured out. I probably didnt help you much though, lol.
I like your lung room a lot, and the ibc is a great res.
ever considered aquaponics? You're halfway to an awesome system....you just need another ibc, fill one with 20 tilapia, and stop paying for nutes...it really is almost that simple...just takes some dialing in.
Keep up the good work!

Yes at 240v then your 1k light would be roughly 4.5amps. I use 120v.

 

[onthaherb]

What about a 6to12k flipflip on a 30a subpanel and A/C on the 20a. What is my best route for an A/C unit two wall units or dual zone minisplit? I'd rather be running the compressors inside a room with powerful attic exhaust so its somewhat stealthy -- anyone have experience with that or lung rooms in general?

 

[whatthe215]

i run window ACs for supplemental cooling in addition to my 5ton. they sit in the exhaust room and just exchange air while it's being exhausted from the rooms through there. ballasts in there too.

window ACs just need to have air exchange in the space they're sitting. i have a 1.5ton in my 4light veg that is just in the beginning entrance area like yours and has a sheet metal cap + 8" flange over the back of it with an 8" inline sucking all the hot air directly to the attic.

6 1ks @ 240 will me ~ 27a so use a 40a breaker.
AC depends on what your climate is like. i'm in very warm weather and need a lot of AC especially since i'm not insulated well.

if you get into the 80s and occasionally 90s, use a 2ton (24kbtu) AC for each room. they pull ~12amps @ 240v. so ~25amps for total AC, use one 20amp breaker for each AC.

60a would just barely handle it (ONLY lights + ACs) ... 48a continuous is max, and if both ACs are running at the same time for an extended period then you're pulling ~52a continuous. i'd just run 100a from the main 100a and call it a day, and put all your fans and pumps on that rather than using circuits from the main.

you're gonna need a few supplemental lights as well to keep them at 18/6 in veg, 2 300w CFLs should be just enough.

flip flop ftw. pull at least 80a subpanel to handle everything including fans and shit.
