16 tubes for 16 plants

Thanks all. I have just changed up all the bulbs for red spectrum.Maybe it's just the color,but the red tubes do not seem near as bright as the blue spec tubes were.
Guess we just see how she goes.

Thats why they called warm white. In fact, they put out more lumen than blue ones. Of course that is for our human eyes. You can add some blue tubes for closer imitation of sunlight. Helps keeping stretch a bit under control.
