We used to used HPS and MH lights indoors lots of them using mostly soil but we did do hydroponics for the last year or so
sea of green style .the thing was my boy was a half ass electrician and we borrowed power by knocking down a wall and tapping into city power.NYC in the 90s HELL YEAH!!!We had a killer room ran about 8 -1000w lights in a basement apartment in Brooklyn. It was a large space that we split in half then rented half out to have bands rehearse in. The area was industrial so the whe building was rented by artists and freaks so no one noticed us. We also grew outdoors in upstate for 2 or 3 years that was seriously hard work but worth it.you can go much bigger outside. Much more money involved back then, now it's a hobby plus legal so less stress. Let me know if you have any questions my brain still works just a bit slower. Happy Friday all!!
That's all I'm gunna say about that....
