Need Electrical Advice and Cooling Suggestions for 8kw Med Grow

[NorCalFor20]

My plan is to expand to 8kw, Im moving to a 3 bedroom house- I will sleep in one, grow in 2, I want to run 4000w lighting+ air conditioner, fans, pumps, etc in each grow (bed)room, so I will need to know what electrical work will need to be done to supply that safely.

Also instead of converting the entire bedrooms with panda film and, reflective material- I will be keeping things clean with a GrowLab 290 (9'6" x 9'6" x 6'7") in each bedroom.

I am already growing with 2kw so I will need to add 6 addtional reflectors, ballast, bulb etc.

My other concern besides the electrical work that needs to be done to supply the power to the room is the cooling of 4kw in each room. I will be using super sun 2 reflectors which are 6 inch air cooled reflectors... Will I need to use a 6 inch vortex to cool each set of 2 lights, for example- Would 2 6 inch vortex fans cool 4kw in the tent?

I would assume I would also need to add a 12inch on a scrubber pulling from the 2 6 inch fans in each tent to exhaust outside? What would be ideal ? Here is a sketch I made:

would have 2 rooms like this

I need ideas on getting the cold air in (see ac in picture) and the hot air out, (smelling clean) and keeping those 1k's cool. My sketch might work, it might not... only thing is i wonder if the ac would be putting out stink air?

So depending on ideas you guys have i'll be looking to add c02 as well if at all possible...

If the plan goes well Ill have 2 bedrooms with 4kw in each growing 48 in each room in the ebb n gro buckets...no veg rooms growing from bought clones, no plant count over 96 dont want to be in fed territory...

Supplies Needed:
6x 1KW Ballast = 800$
6x 1KW Bulbs= $350
6X Super Sun 2 = 690$
4X Vortex 6" =640$
2X Vortex 12"= 800$
2X 12" Phresh Filter 350$
24 ebb n grow buckets $300
48 pot ebb n gro sys/w res $1,200
2 GL 290's $1600
2 12,000 BTU AC's $1000

7,730$ so far not incuding electrical work, medium, nutes or misc items

Hmm, i ran 4 hoods off one 6" vortex no problem, at half speed the output was only about 102*F. I used a manual speed controller to adjust the output temp.

For power, well I always recommend 240V, cost me $900 to have a 40A and 2 20A 120V circuits added to one bedroom, if that helps. With 4 1000's that's 18A, and the AC (120V) would need a 15A circuit to itself, so I think you should do a 30A 240V and 2 20A 120V circuits per room. I'd run the scrubber in the tent and ozone outside it, and have the hood exhaust exit above the window AC thru the window. Tricky to get the cold AC air into the tent though, how would you duct that? Can you do this without tents or are you using the tent as an internal airlock for light leaks or something?

NM on the Ac's, saw on your pic you are going to use the portable ones.

My idea, is that running the 12,000 btu ac in the "lung" room would lower the ambient room temps... i could exhuast the hoods right out the window that is a good idea.... The bedrooms i am growing in i would still like to use for storing nutes , supplies, ressys and maybe throw a couch in there incase i want to smoke out with my plants, so i am using the tent, also easier to get negative pressure in a tent, it also makes the setup cleaner not dealing with hanging panda film or refletix all over the room (which would be too large for 4kw anyway)

im gonna finish this grow i got now, setup the 4k in one bedroom do a run that way then after harvest with 4k gonna hook up the other bedroom that way i can save a bit of money i have about 10,000-12,000$ budget after this grow is done. but once i get the 4kw grow done i should have plenty for budgeting the other 4kw in the other bedroom

Norcal - I'd suggest that you suck the air through the reflectors, not blow it. True story here - I had my stuff hooked up like you are showing. The flexduct gave out and so my fan was blowing hot air around in my cab for about eight hours. Ruined the crop in week seven of flower.

You should do some reading here on those portable a/c's. Not too many people who have them are happy with them.

The way you have this set up, you will constantly be replacing the air in the room. That's going to make your a/c be running a lot. If you put filters on the intake for the lights and then run the light exhaust outside, that should take care of your odor control. You wouldn't really need a separate scrubber then.

you want a couch in the bedroom so you can smoke and chill with the plants. I like that idea but you gotta have a big bedroom in order to have the couch fit.

If overtemp is a worry I'd hook the 240V relays timer up to one of those hi temp shutoffs, that will prevent Pharmacan's issue from coming up. Never grown in a tent but I can see the appeal.

nor call those Ac's are crap I'm am running a 6 k grow not venting the hoods and the 2 12000 btu's didn't do the job...so I would go with a much bigger cooling unit... i just bought a 24500 btu window ac and build a ac box...it is a huge pain in my ass.... do you have a wall or window that you can put a ac through?

I am into day 3 of using my 12000btu portable ac and it kicks out 12,000btus of air, it does what it claims to do, cools my ac'less appt +2400w of lighting no problem....i like it so far unless the cooling capitity drop signifigantly i will be purchasing another one for when i double my grow...

you want a couch in the bedroom so you can smoke and chill with the plants. I like that idea but you gotta have a big bedroom in order to have the couch fit.

Couch is no big deal, i have no specific house in mind yet, im going with a manufactored home so i can customize a lot of diffeneret options....

i have had that happen before like Pharma's incident but my temps are always pretty low i spend extra $$$ on power to keep things cool and if that happen temps may rise up to 85 but i am a full time grower so i am always around my grow room....

ur problem maybe that your not venting the hoods, my air conditoner only is for keeping the room cool not fighting the heat of a non air cooled bulb i can see how you need 20000btus+ to cool your area but it maybe cheaper to air cool your bulbs and vent the bulb heat outdoors....

Lke i said, after this current 2k grow finishes im going to do a single 4kw tent run and see how things work then if all is well i set up an identical setup in a seperate room....

any additonal advice is accepted, i may end up having to do this myself, its hard for me to get an electrican i can trust in so cal and my electrican in nor cal i couldn't get to come down here even for this....

.....just buy a wireing book with lots of pics,.

i always stand a piece of ply wood on four bricks for a stool that wont make you the ground if sumthin were to happen.

Other than that wirenuts must be very tight and always use a plug in type of tester before pluging anything in. the testers are cheap at the hardware store.
