Jump in with both feet. You won't want to quit. I tried for many years outside in soil with very little luck, ripped off most the time. I tried phototrons inside, good for veg sucked for flowers. then my bro gave me a 400HPS cause it was too hot for his closet. I looked around and got a 6 plant drip system As drip and areo seemed the way to go. My first grow was crude but I got 4 oz's of kill. My room has mylar ,AC, dehumidifier. Good ventilation is a must. And most of all lighting. At the very end of my second grow I added a 1000HPS still got the 400 for side lights. When you go inside it's all about your lights. Get the biggest you can and you will harvest more. Side lights can be flouro's.
