The six buckets are in two rows:
The Northern row (L-R) #6, #5, and #4
The Southern row (L-R) #3, #2, and #1

Because the air and water are fed from the back of the greenhouse, plants #6, and #3 are closest to the front entry (West wall) and plants #4, and #1 to the East.

Plants #6, #5, and #4 have their antenna assemblies positioned in the “12 o’clock” area of their buckets. This allows the led light to clear the 6ft bamboo shafts, and be lowered very close to the tops of the three-tier cages. Because of this, the Southern row of plants #3, #2, and #1, had their air lines, water lines, and antenna assemblies installed in the “6 o’clock” area of their buckets. Plants #3, #2, and #1 show signs of life, but I suspect the incorrect orientation of the antenna may have retarded growth.

To test this theory, I have adjust the antennas of the two end plants in the Southern row: #3 (left) and #1 (right). Plant #3 was rotated so the antenna assembly was as close to North as possible, given that the overhead led light was in the way; I got #3 to about the “11 o’clock” position. As for plant #1, I rotated her counter-clockwise until the assembly was in the “1 o’clock” position. Plant #2 I left alone, as a control. Southern row, middle plant, the only antenna “facing” South. Place your bets: anecdote? Or fact?

Thursday Edit: I rearranged the buckets into a horseshoe shape with the opening to the South. All the 6ft bamboo stakes were reoriented to face North, and buckets physically adjusted so the antennae can better fit around the light. Should have used a 4ft+ or longer bar light, instead of this rectangle tent-light. I didn’t take account for the lower light height in germination. Probably could have waited on attaching the inverted tomato cages, too. Just mesh wrap the buckets, and lower the light. The coils could have draped over the edge, due North, until it was time to install the cages and bamboo stakes (after raising the lights)
