More Light
Plants that have just entered the flowering room can stay on the perimeter of the garden for a month until the more mature plants directly under lamps have finished flowering. This simple trick can easily increase harvests by 5-10 percent.
A light mover moves lamps back and forth or in circles across the ceiling of a grow room. The linear or circular path distributes light evenly. Use a light mover to get closer to plants. Keep plants at least 12 inches away from a lamp on a light mover. The closer a lamp is to plants without burning them, the more light plants receive.
Manually rotate plants so light reaches all the foliage to promote more even development. Use a light mover or put the containers on wheels to make the job easier.
Add a shallow shelf around the perimeter of the garden to use light that is shunted into walls. Use brackets to put up a 4-6 inch wide shelf around the perimeter. The shelf can be built on a slight angle and lined with plastic to form a runoff canal.
