The most successful growers make sure they concentrate on these areas.
As light levels increase, be sure to monitor other environmental elements, including heat, carbon dioxide, humidity, and nutrient supply.
As light intensity increases, the light spectrum becomes more important. Natural sunlight is intense and has a broad and balanced spectrum. Indoor plants require the same high intensity and broad but balanced spectrum.
The reflector directs the light where it is needed. Well-designed reflectors are made of quality materials that have a long service life. They deliver a high percentage of the available light precisely where it is needed, uniformly.
