these gals were grown under two 2ft flouros warm white throughout their lives in total 36watts through their whole lives, the buds are lovely but not that big which is a downside, either put another floro ion or buy 3 screw in flouros and suplement ur garden with these. i havent but if i wanted more bud i wud of dun this OR buy mh or hps like 150watt one or summit depending on ur situation.

happy growing
