Hey everyone, I'm into my latest grow and trying something I haven't done before. I'm using a low-power LED panel over each plant until it's time to flower. So far, here's what I've done with this crop: Sunday, August 29, 2010, is the first day in the Ebb and Flow system. Plants are about 4 inches tall from the lava rock with the exception of Tub 4. That one is barely clearing the lava rock. Tubs are numbered Tub 1 = Front left, Tub 2 = Rear left, Tub 3 = Rear right and Tub 4 = Front right Each plant was rooted in an aeroponic system and then given very mild vegging nutrients for two weeks before moving them to the Ebb and Flow system. All four clones were under a single 28 watt LED "GlowPanel" for this entire time. The initial nutrients are half strength General Hydroponics 3 part Flora Series. The LEDs are always about 4 inches above the plant tops. Room temp is 78F and no air conditioning is necessary to maintain this temp. I have a fan blowing into the room from a larger room next to it just for some air movement. Pump is set to my usual timing of one hour on, two hours off.
