Newbie grower here with plenty of questions. First off, I know color temperature and wattage are important in choosing lights, but I'm curious about lumens. I haven't seen as much about them and I've heard they're important for bud density and growth. I just ordered four 40w CFLs (6500k) for a small grow. They each produce 2800 lumens. Is that enough for a couple plants? They'll be used at night in addition to the daytime sun for a 24/0 light schedule. Sent from my iPhone using Grasscity Forum
