While i agree blurple lights may not be as effective as HID or quantum boards, i wouldn't necessarily rule out the blurple lights. For the price, the yields aren't so bad. It's just important to choose a better quality one. The one i linked, is low wattage however. I would suggest spending at least 100 dollars on a 250 actual watt blurple to ensure you have a decent yield of a small crop. If i were to suggest a "cheap" light, This would be my choice. For 20 ish dollars more, you can get 600w.

Problem is, they're not very efficient. Cob lights could also be an option. For this, the 100w cfl 6500k bulbs and lamps would be my choice. You would definitely get more wattage from the same money.

Edit: also, if you don't mind possibly having to send it back for another, you can get it used for 89ish usd
