I'm looking to get a new house probably 3 maybe 4 bedrooms.
after i get my Legal plant count upgrade... I want to run a sealed grow room, AC, Fans,Dehumidifier and Co2 and 5-1000 Watt Grow lights in 2 rooms. I know i will need to call a electrician to help setup and upgrade the AMPS to the house, but im a noob to the electricity haha do i need a certain size house to have that much wattage in one house?? or is it all good if the electrician comes and upgrades my AMPS and circuit panels? i know he will charge a arm and a leg for it but thats the sacrifices haha

Easy as fuck. Put a 50 in your breaker box for each room then you get your lights that either run off 240v or jump 110s off of them for everything. Cost you about 200 bucks for the wire and everything

So you're looking to do 5x 1kw lights in each room,10kw total?

At 110v that's 90.9 amps!

When running continuous loads (devices run 3 hours or longer) you can only safely use up to 80% of your circuit per breaker.

You'll need some serious electric!

At 240v each 1kw light will draw 4.5 amps each,that's 45.5 amps.

If it were me I'd have each room wired up 240v and a 30 amp breaker for every five 1kw lights.

I would add amps for cooling and dehumidification. Pull wire for 60 amps imho, set a subpanel to feed lighting controller and hvac. You can only use 80% of breaker ampacity.

Yes,I should of added that my last post was only accounting for lighting and lighting only.Not the serious amount of air conditioning,pumps,timers,fans,co2 generator etc.

And 60 amps will only be good for all 10kw of lighting only as 80% of 60 amps is 48 amps and that's if going 220/240.

If going 110/120 he'll need even more.

10000/110 = 90.9 Amps and at 80% safeload of breaker capacity is 72.72 amps!

For lights and air conditioning,dehumidifiers,humidifiers wire everything up 220/240,for fans and pumps wire 110/120

Subpanel per 5k room should have stated that.

Should have plenty of other outlets available to plug in an air conditioner. The thirty should just be for lights. 240 X 30= 7200. 7200 x.8 = 5760. Puts you there with plenty to spare

But you should use 220v as a safe measure...

1000w/240v = 4.16667 Amps and 4.16667Amps x 240v = 1000w but doesn't take into account the extra 10% to 15% power the ballast consumes.

If you run a five slot square d you could put em all on their own 15 or 20 or whatever maybe just stagger your start up times about 5 or 10 minutes
