Lighting

Lighting is one of the most important parts of the grow. You must calculate the ratio of space to light so there is not too much light on the plants for optimal health. The light cycle must also stay consistent from light to dark or it can cause problems further down the road. 

For the germination and vegetation stages the range for the cycle of light should either be 18 hours of light and 6 hours of darkness. However keeping the lights on for 24 hours per day is also an option as the light will not harm the plant. It is possible to keep a plant in the vegetation stage as the only way to continue on to the flowering stage is by changing the light cycle.

The flowering stage’s light range should be 12 hours of light and 12 hours of darkness. The reason for using and changing the light cycles is to accurately simulate the light cycles that they would grow in, in their natural environment. Longer days in the summer and shorter days in the fall. 

Keeping the room as air tight as possible to create an envelope that seals the light in and does not allow light to leak out, is needed to encase the plants in their own environment. Using a white tarp or grow foil are useful options to help maximize the growth of the plants.
