hello everyone, hope u can help me. as funny as it may sound i am dead serious. i only want to grow 1 plant at a time because i dont want to attract any attention and i just need to know the best light to use. i'll be growing in a space approx. 6 ft high by 18 in. deep. i read about the new led lights but i hear they lack tru power. i'm afraid to use hps because of the heat buildup. i really need help because i cant afford to buy anymore so i was looking to invest in ( build my own) gro cab. plz i'm at wits end because there are no definitive answers. thx to any responses.
