hi , I'm new to growing. At present trying an out door grow in a bid to learn something before I take the plunge. And have a target to beat. HLG 260 . R spec is where my head is and I've less than 3 ft space to fit. . . local weather would be between 3 and 18 . With highs 28 and lows -4 . High humidity most a the year. . I don't want a high electric bill . Use the light at 200 watts 100 for 2 fans . For 16 hours . In my newby state that's a fine idea. .
