@Carlos_Danger ... Welcome.
Without knowing anything about your indoor setup or your local latitude and climate I can't comment on the wisdom of starting your seeds outdoors and then moving them in. Personally, I'd start them indoors where they won't be exposed to insects, rodents, unwanted spores, etc., veg them long enough to take clones and then take them to flower. But that's just me.
Although it sounds like a good idea creating parallel grows with different technologies, you're looking at a double workload and double expenses for nutes. Personally I find it challenging to deal with a single medium grow without letting the process take over my life. But that's just me.
As for the lighting issues, what's the grow environment like? 1 tent/room or separate veg flower areas? What are the sizes and ceiling heights? There are some really good options for LED fixtures both DIY and ready to hang but I'd need to know what you consider a reasonable cost and what micro mole density you want to achieve.
In any case, good luck with your grow.
