The second area in which we increase our energy efficiency is

through rotation of the planters. In this case, we mimic a

natural process to get more use out of the energy provided. It

is quite easy to explain: normally, the sun travels from east to

west above the plant once during the day. As a result, the

plant is uniformly illuminated throughout the day. In this case,

it has a shadowed side in the morning, which in turn gets light

in the evening - and that restores a kind of balance in which

the whole plant gets even lighting throughout the day. If we do

not have a light source that moves, however, one side of the

plant will always be in shade. This reduces the lighting's

efficacy significantly. To eliminate this deficiency of

conventional indoor farms, we rotate the plant - here again,

we may save up to 50% energy.*
