Carbon filter, exhaust hood/fan for your light (1000 watts give off lots of heat that you have to get rid of), circulation fans to move air through your canopy, cal/mg for when the cal/mg monster shows up, humidifier/dehumidifier/heater/air conditioner as needed., do you have a good water source? May have to look at a water filtration system, (reverse osmosis). You don't have to have everything to get started, read through as many different grow journals as your time allows, and note what other people are using or doing that may apply to your situation, learn from their mistakes then dig in and make some of your own. People here will help, you just have to start a journal so people can follow along. Go to Introductions and give everyone a big hello. Good luck on your grow. Welcome.:Sharing One:
