Large scale electrical help

Gquebed said:

Firstly, I know nothing about electricity except the very, very basics... so... tech jargon will be lost on me...

With that said, I'd like to know what would be required to power 100 individual 25 sq ft areas, assuming that each of these 100 areas would be using one1000w HIDS.

To help better understand what I'm trying to do... imagine a warehouse subdivided into 100 individual growing spaces that are 5X5 each. Each of these individual spaces would require their own electrical outlet for the 1000w light AND likely another one for fans and etc. How would this need to be set up and with what?

Also, entirely separate from that... the warehouse space that surrounds these 100 growing spaces would have to be air conditioned and the air would need to be exchanged every few minutes, as each of these grow spaces would of course be exhausting hot, co2 depleted air, with passive intakes. Supposing this warehouse space was 4000 sq ft (with a 20' ceiling, so 80,000 cubic feet), what would be the electrical requirements for that?

What.. no veg room?

You’re gonna need a lot more than the AC supplied with s building to cool 100 lights in 100 individual rooms. Not to mention the building materials cost, labor and time of such construction would be OUTRAGEOUS.

Why?

You are going arse first here. Use CO2 and air conditioning, only vent hoods which should draw air from outside and dump it outside again. This way you are not venting air faster than you can condition it. Will save you money and increase yields/potential.

You honestly need a professional, and I am not talking electrician here, you need someone with experience in building large grow ops. Based on your question, you are out of your depth, but that is OK, it keeps more people employed.

5A each @ 240V, your looking at 500+ amps just on lights alone. That doesnt include fans,controllers,pumps,hvac,and normal building lighting and electrical supply etc. Youre looking at 1000A service for a op like that.
Why (100) 5x5 rooms and not just an open floor concept to reduce costs on building materials, hvac and individualized equipment for each room like dehumidifiers etc?
Like ANC mentioned, you would want air pulled from outside & running through all of the air cooled hoods and exhausting right back outside. Far less HVAC cost since you would only require a large exhaust system to do that and you wouldnt be wasting conditioned air that you paid big $$$ for. How much is a kwh in your area?

I'm guessing this is going to be set up like a self storage/ brew your own idea. My friends and I have been brain storming this idea.


Other problems we thought of are.

Bugs, How do you treat 100 different areas? Also how do you keep bugs out.

We also figured it would have to be classified as 100 residences.

Security for each room?

Your customers, I've worked retail and I know too never understatement the stupidity of your clientele.

We figured it could work if the customer came in cut 4 clones off a mother and we did the rest. Much like how some wine is done. Then you hand them back 4 full untrimmed plants.

Then you could rent trimmers ect...

Also look at commercial insurance that will be crazy expensive I'm guessing.

My electricity costs 23.5¢/kwh

Plus all the "rider" and "carrying" charge addons?

The price i said is without all those bullshit addons....

Ambitious idea...not very practical though. It would be much easier to build fewer larger rooms for cooling/ventilation sake. The power distribution is pretty straight forward, roughly 20 amps/room. The hard part would be the ventilation. You could use negative pressure to cool the grow rooms...pulling conditioned air into each room from inside the warehouse and exhaust it through a filter to outside. Pulling air from outdoors would bring condensation issues in the hoods. Doing it this way though CO2 would be a waste and Im sure you could imagine the ventilation system would be complex for that many rooms. Going sealed with A/C...a small window unit in each room..would be much easier to build but would use more power.

The best way to go depends alot on how much power is available and your budget...and what you think someone would pay to rent a closet to grow in

PM me if you want to discuss further.
