Shipping container grow room questions

hello, newbie grower here. I know I have my work cut out for me In reading and learning how to grow. However, right now I would like to focus on the grow room. I live off grid in NW Arizona. It is considered high desert climate. Our moisture is highly dependent on the summer monsoons and winter snow.
I have a med card as a cultivator and can grow up to 12 plants. My main growing season will be outside for the summer, but I would like to try to have two smaller ones inside from fall to spring. I currently have a small (8x20) shipping container I would like to convert to a growing room. I have read some of the posts here on shipping containers and did get some info out of them. I however, I thought I would try to post my specific situation for added help. I hope this will not be too repetitive of a question for this group.
With the little bit of knowledge I know, I am thinking of keeping this one room, and let it go from veg to flower. I am more concerned to get maximum per plant than more plants, so would keep it to a max of 8 plants. Would like to use formboard for insulation and keep wood floors. I would be using soil as a grow medium and would create some sort of drainage system for excess water to drain. I realize I need some sort of ventilation.
The biggest challenge is that I have no choice but to use solar/gen for power. Because of this I am seriously looking into LED lighting.
Assuming I can be successful using the container, 8 plants is a good number and I can pull this off just using solar (hopefully minimal to no gen use), here are my questions:
How many and what kind of LED lights?
What type of ventilation (size of fans, exhaust, etc)
Any suggestions on floor plan?

Thanks for any help

save yourself time and money bro and just don't do it if you're going to half ass it. but in anycase good luck with your grow brother

Thank you for your feedback. Could you be more specific as to why this or any part of it will be "Half Ass"?

What are the temps outside during the time of year that you want to do this? Temp control will be an issue and it will take a bit of electricity to heat or cool the box! Also humidity will be an issue that you have to address.

I have learned that humidity above 45% means that I WILL have powdery mildew!

Air movement is important also so oscillating fans for the win!

Have you added up all of the electrical devises that you will need and sourced the solar setup that will supply enough power?

A typical 600 watt led pulls around 2.5 amps at 110 volts.
My 440cfm fan pulls around 4 amps at 110 volts
My oscillating fans pull around 1.5-2 amps at 110 volts depending on the setting.

My rooms are in a 10"x16" area split into two rooms. I use a 220cfm fan to exhaust the rooms through a passive intake. It is under the recommended CFM for my room size but if I increase the CFM's I have to increase the heat to compensate for the 40 degree air coming into the room (winter time). I just set up my room recently so I haven't had a heat issue yet but summer will be here soon enough.

I don't think solar is plausible. To generate 1kW you would need 10 standard 2'x4' 100W panels at ~$120 each. Add in deep cycle batteries and automation for moving the panels with the sun position, $3000.

Alternately, you can buy a gas generator for less than $500 and fuel costs of about $.25/hour.

Being fully off grid has been a dream of mine since the late 60's but the older i got the less hippy & more yuppie lifestyle i lead so it killed the dream , i could go my entire life without television but cant live without my stereo systems which need to much watts & amps for solar.

Kudos to you for pulling it off.

About your questions , im not a solar expert or versed well in off grid living but i am very educated in setting up successfull grow rooms , with your energy situation i dont see any options that would make growing indoors worth while, unless you have enough panels & power storage where you can draw 1,500 watts per hour your pretty much limited to using a generator , the gas costs would kill you.

If your dead set on doing it cut the top off the shipping container & replace with clear corrigated roof panels to make use of natural light as much as possible.

I wish i had better advice but your task at hand is complex,also if you plan on using foam board insulation make sure the type inso you use is rated for interior use , some types foam board insulation will off gas toxic fumes & therefore are not to be used in interior spaces,insulation like polyisocuranate will off gas.

Powering the grow is the problem imo.

Thanks for the feedback

Our outside humidity is on the dry side except for monsoons. Maybe in the 25% range. I have no idea what am out of humidity would be inside with 8 growing plants.
This is our first winter living here so not sure how Jan & Feb will be, but so far the lowest it has gotten at night is high 20's
I am familiar enough with solar to understand costs. We are on solar now. If this inside growing ends up a bust, I will reuse all solar/ wind gen equipment in other places so investment cost does not hurt as bad.
I have not figured out energy needs because I am not sure what I need for equipment. That is why I was asking about lights and ventilation.
to my knowledge consumer generators will not hold up to the heavy use it would get in my situation.

I think I addressed everything.
thanks
