I'm watching some girls bud under cmh lighting. Real nice. 315 watt = 600 watt MH and HPS and a 630 watt = a 1000 watt. Much less heat than MH and HPS. you'll need to make it buy a tent if you haven't got a room you can use. You'll need extraction fans intake fans a container to mix your water and nutes and fans to keep leaves flapping. Humidifier, dehumidifier, cooling for hot times. Cheers

I spent about $1000 for my entire setup although you could easily cut it in half or more. There are budget setups too, but you will sacrifice yield and quality.
*depends on your current conditions
GOOD LUCK!!
