Help setting up medical grow

Hey guys wanting to setup my 25 plant medical grow. It will be housed in a 100 sq ft shed with a shutter fan for ventilation.

trying to decide on hps or led and how many watts?

plant spacing? Soil vs coco vs hydro

veg time?

any tips or anything would be greatly appreciated. Maybe a greenhouse is better suited for the time of year in Canada. I’m not sure. Just looking to maximize my yearly yield.

Im a soil guy...wouldnt change for anything. Its easy. Easier actually. Your 100sf space will heat up quick so id buy a couple nice leds. Figure roughly 3 to 4 plants per 4x4 floor space. Keep em tidy and short. I'd use grow bags, they fit snug together. But it's a personal decision. I like led bc they're cool running and for a small space I think its safer. Buy the best you can afford. You're gonna need at least 300 to 400 watts...more is better. I ran 600w Blackstars and had great results. But just bc it says 600 doesn't mean it pulls 600...do some reading in the LED section.
I hope that helps.
