im wanting to install another breaker box in my flower room ill be running 2x1000 watt lights 6x 600 watt lights....pumps fans portable air conditor etc....could someone point me in the right direction on what kinda box to get...do i use the box inside my home to run a 220 from it or the outside box? 3 of my 600 watters are gonna be ran in a straight line with 8" airsealed hoods..... and 8" ducting ill be drawing air from under my home were its cool to pump in and cool the lights then right back outside...anyon tell me what kind size fan i need my room is 15x12 7 tall the 1000 will only be ran in the winter time...i would hire someone but that not an option for me ive hooked up breakers ran wire before just not to detailed on this mabe send me some links show me what i need and ill run to lowes grab it

2x1000=2000
6x600=3600
Running total 5600W continuous draw for lights alone
Aircon load assuming 4000BTU per 1kW = 2.2ton which would need about 3000W
Running total 8600W
Assuming 1500W on miscilaneous pumps and fans
10kW total load
Assuming you're not staggering anything you can only run a circuit at full load for 3 hours. More than that and you can only run at 80% of rated load.
(10000/80)x100=12500W
Assuming you're running 110V. You need breaker box rated at over 115A total.
There are too many assumptions for you to base a purchase off those back of an envelope maths. To help make a proper recommendation it would be nice if you provided details of the AC you'll be using (power draw would be ideal), how many fans and pumps you'll be running, whether you're on 110V, 220V or 240V.

Even if you are running everything at 120 as long as your using 2 separate 120 volt legs the 220volt calculation is still being used.
If your using more then 1 circuit and they are all off the same leg then you use the 120 volt calculation. Put your meter on the black wire of 1 circuit then put it on the other black wire of the other circuit, if you get 0 volts both circuits are on the same leg, if you get 220/240 then your on the opposing leg.
You should take the time to research everything you need yourself, this way when shit happens (which it will), you'll know how to deal with it.
To do a proper load calculation you need to put up all the specs of all your devices and info on how ur using them. Ex. 2 flower rooms on a flip.

my portable air is 12,000 btu 120 need to know what size fans to get to cool the 600 watters they will be 2 rolls of 600 watters 3 in a roll.....ill prob need two differnt fans to cool those but which one? ive got a 740 cfm duct inline blower fan 8" ill be hooking onto a filter and taking the air out of the grow room it runs on 120....fresh air will be brought from under the house thou 8" duct work and vents..with a cheap wal mart fan with a custom made front plate to mount the duct....my pumps will be 6 eco plus 396 i think there 35 watts each..my lights are one dual 600 watt...and the other 5 apollo single balast will be mounted in another room...to keep down on heat they run on 120...

I would go with a 100 amp panel. Then run an 8 light controller to that, use #6 wire. 5600 watts on 240 will only pull 25 amps but will require 50 amp breaker. Then add a few other breakers. I'd deticate a 20amp to ac, then two 15s to whatever.
Your ac isn't enough, depending on your location it might work in the winter...
Also it worries me that you asked where to even hook this up too. I'm not trying to be a dick but be careful. It's very simple shit. Just inbox me and I'll walk you thru it all.
