840w LED lights 15 amp or 20 amp breaker?

Shit is the standard here for any “affordable”housing, anything modernized with similar square footage is easily 2-3x my rent
I'm so sorry to hear that. It took me 3 years to save up enough to repair it because it failed leaving Me with only 3 working outlets. Lol man I'm so grateful now to have normal power but I still need to do a lot of work. I'm on a disabled vet salary to make things even worse living in a criminalize cannabis state

Central air or any 120 window units? If you need window units find the circuits with the least amount of load on them. Ac 120v pulls 15 at 12,000 btu

I have central air(sort of) lol and a 15000btu 120v window unit, got replacement fuses on the way too452EA09B-18B4-4649-9839-A051D0542288.jpeg
This mf barely works lol

I had to rewire my entire home because it had antique breakers and glass fuses. It's a miracle this house is standing. We got inside the walls and it gave me chills. I put in modern out side meter breaker box. And breaker box indoors. No we're running 2 dedicated lines just for the grow. 220v and 120v dedicated lines. Gear doesn't have to work as hard if it's 220 meaning longer lifespan.
Wow that is fantastic good for you!

Knowing that, you want to simply see how many circuits you have leading to the space (or, if not set yet, figure that). Based upon the number of circuits and what you will use them for, you can determine amps and breakers.

If all you need on those circuits is one light each, a 15a is more than enough. It would be circuits that never come close to tripping.
If you only have a few circuits in the grow area, make sure to install breakers as high an amperage as safely allowed by wiring and electrical standards.

I'll be pulling quite a few amps. Need at least 30amp breakers I'm guessing. That's why we're running 220v too so everything won't be piled up together and the ac and a couple of lights won't have to work as hard

It helps to stagger light start up times , if running multiple rooms you can also have one on while the other is off if they are both 12/12

You’ll probably have to hookup the dryer plug to it yourself, I got mine used and already wired on eBay awhile back

Yeah, it’s just plugged in to regular dryer outlet like this one, I can’t get a pic of mine rn cause my lights just came on84DA84E5-3A2B-477C-90D1-69665BA0EF08.png

You don't need a fancy lighting controller with relay's that cost 100's, unless you want to fork it out. I would suggest you do, because they are pretty nice, but.. You could just run your wires into a small cheaper load center, or sub panel box, etc. Split the 240 back into 120 circuits at the box, just like the lighting controller does, but without all the added stuff.

If your room is literally right next to your main panel, I would still run to a dedicated sub panel just for the grow room equipment myself, but you could just add a few 20 amp 120v breakers going to some outlets instead. Add another new circuit or 2 with cheaper wire, if your not gonna be using that much wire or making a long run anyway...

Make sure you calculate your entire load for your house, and find how much aperage you have to spare before you go adding breakers or anything.

If you find you don't have enough juice.. "Flip flopping" is a neat way to run twice the amount of equipment, with less available power. You just run 2 separate rooms instead, each using roughly half the amperage, and you set the timers for slightly less than a 12 hour on light cycle for each room, so there is a gap between the next rooms main loads/lights firing up. There are cons to going this route of course, but using motorized dampers can help to redirect flow, and not have to buy as many doubles for some equipment that might be needed, like AC or exhaust fans, etc.

They even make flip-able ballasts that automatically switch to the other bulb, without using more current.. You could probably make your own flip box that plugs into a ballast, with relays or whatnot for cheaper too, but I never looked much into it, or needed too...

Appreciate the information. I will consider this in the future. However at this cost, $150 I can't pass up the ease. This should do everything I need.
