Electrical help, main breakers and subpanels

[frankfast]

lots of info here, i just went through all this my self, but i did the smart thing hired an electrician! now i have a brand new 200amp panel that feeds right off my meter instead of tapping into my house panel.

How much did that cost you?
A friend of mine just had someone upgrade his electric for a real old set up.
It ran him about $1200.

it was $400 installed with the panel and he ran 1 40amp 220 line for me for my flip box, i allready had the 10/3 wire for this.

also im not sure what he got and what the electical company got but they had to come out to,

but now i have a safe brand new 200amp panel just for my grow area

I want something like frank's setup but don't know where to find a trustworthy electrician

looks good-

like marty said balance the load across the poles. look like you just need some two pole breakers and youre good. one benefit of running 240 is it splits the load across two poles instead of one. so 10 amps at 120 V across one wire, or 10 amps at 240 across TWO(2) wires. resulting in five amps on a conductor instead of ten. meaning? way less wire. 12 gauge is WAY cheaper than 8.

good job, man!

the 50A breaker the subpanel runs from has two poles on it but I only used one. does this mean I can just connect the extra pole on the breaker (I am using a service line cable I picked up from lowes that has a ground, a black cable, black/white stripe cable and black/red stripe cable, I haven't used the fourth cable in the bundle) and I will have 220V?

yes-

the red black, and black are the power legs. the white stripe is the common, and the bare wire is the ground.
hook up the red, black, and bare for 240. hook one leg(black or red), the white(common), and bare for 120 volt.

both voltages only use three conductors, but it takes four to make both.2 120v legs, a common, and ground.
