How to grow weed for dummies

I’ve been smoking cannabis for around two years now, and I’ve been extremely interested in the effects of each strain, and figuring out the differences between terps over that time. Me and my buddy have been on leafy every day looking into strains and their thc percentage, parent strains etc. We want to start growing soon with two parent strains to create a new one. Where is a good place to buy seeds? What equipment do we need? Any answers or any other general advice would be awesome and much appreciated.
