Problem is weight limits. so your 2 week cure is probably out. 5 patients still only gets you 12.5 oz weight limit which forces you to stagger the harvests. I think most shops out here are paying 3k/LB but I wouldn't know for sure, don't sell to the shops. My patients know other patients and it just breaks down from there. I'm running 2850w of flower and 1000w of veg in a single bedroom. Trick for me was just using extensions. Ran one from the kitchen 20a and another 15a from the hallway circuit. With the bedroom's 15 amp that gives me 50a to work with. I don't even vent externally, just back into the room and then cool it with A/C in the summer and good ole michigan winter when it permits. With room and other expenses, each cycle (2kw flower room) is costing me about 2,000 for rent, elec, nutes, pots/medium, co2, ect. I get about 2lbs, trying for 3, so yes it's profitable, just not greatly. And you have to be able to peace it out quick or your sitting on it illegally and your card won't help u for shit.
