One of the common mistakes indoor growers make is not maximizing their light. Indoor gardens require a minimum 33 watts per square foot. For example, a standard 4’ x 8’ tray (32 sq feet) with two, 1000 watt HPS, you would achieve 62.5 watts per square foot, doubling the recommended amount of watts per square foot.
If you do not contain your light to the plants in the growing area, you waste your light by illuminating your walkways, walls, etc. You are not growing concrete or sheetrock, you are growing plants. It is extremely important that the light penetrate only the plants. The light should not escape the plant area.
The easiest and most cost effective way to contain your light is to use white plastic divider walls, leaving a 2” gap from the wall to the plants. By doing this, you should see a dramatic increase in your yields.
