Hello @Skatz welcome to the forums and thus the community.
You did really good you didn’t cheap out on gear and that’s good.
Now your lighting for 4 plants is lacking but the company claims
“Vegetative Coverage at 44”: 5x5ft
Flowering Coverage at 18": 32": 4x4ft"
So that’s about the best information you can go off of until you get more lighting.
Do a grow and see how it does, it will grow bud I’m just unsure if it’s gonna grow the type of bud you want and are expecting.
Aside from that your gear is solid.
As for the process.
When your ready soak your seeds in 1 part hydrogen peroxide, 2 parts water for 20hr then place in a container in between a damp piece of paper towel (don’t drowned the seedling).
I would Suggest some Mykos, great white or voodoo juice, or tribus something like that.
Make sure your soil is mixed with 30% minium perlite it needs to be airey for good root growth.
Fill the mix mkyos and soil perlite into a red solo cup with drainage holes on the bottom.
You could go to the hardware store and get seedling soil I would strongly recommend this although not needed. Light soil is best for the early stages.
Use veg cycle and wait until the plants leafs touch the edge of the solo cup then it’s time to pot up. Into your 5 gallon pots.
SCOG is a great idea but you may be better off with a a net or two and just low stress training along with fim/topping.
SCOG setups are best well though out in advance, because once you SCOG them it makes them impossible to move unless you build them on casters I suggest your browse around and work a SCOG setup in the future made out of pvc and rope or whatever.
@Not2SureYet has nice knes as does @merlin44
Remeber to have a system to be able to catch the runoff water that drops out the bottom of your 5 gallon pots, you will want to read this with a ph and tds meter so you know when to feed.
I know the soils rich but you will have to feed bloom. Nutrients and cal mag in flower.
