I would out those outside if your in a good area. They will do better, and yield more for your time. And then go to Amazon, buy 600 watt HID. You will need 1 metal halide bulb, 1 high pressure sodium. Get a exhaust fan (cann-fann, inline fan..etc) And then i would say use that closet you have. Like gut it and make it a dedicated room. Or if you want to go advanced look into building a room in your garage or something. Its really not that expensive. 500 - 600 bucks and your started. It will be a continual investment though, remember electricity. Soil, nutrients, water. Etc. Feel free to send me a message if you have questions. If your willing to learn, it will come in time. Keep growin!
