Advice needed!!
I have a green house with a few windows, and about 6 banks of fluorescent lights. I am coming to the conclusion that this is just not enough lighting. Plants are growing huge but not flowering. I am gonna get some LED grow lights and was wondering if anyone had some advice on what ones are the best. I have power constraints due to not having enough power going to my greenhouse, so they have to be energy efficient. I am hoping they won’t pull too many more amps then the fluorescents???
Anybody have any suggestions

I think you need different bulbs to get good "flowering" rather than just "green growth"... might be a lot cheaper than buying new LED fixtures. Look for bulbs marked "warm white" in the 2700K or 3000K range.

We have half warm white and half cool white bulbs in each fixture.

I have two diffrent hues mixed in the banks. Some warm, and some cool. I read that that was needed to sustain all stages of growth. What do you grow under them??? I have mine on timers to come on about 16 hrs a day???

If you're getting good growth but no flowering you might have to go to all warm white bulbs in your supplemental lighting. We have no natural light, so we're using both types of bulb for 100% of the light.
