There are two important factors for providing light to house plants which are intensity and duration. Of course we all know there are varying intensities of light and the term which we use to calculate the intensity are referred to as PAR, photo-synthetically active radiation. Amount of light exposure is based on plant types typically in ranges between 8 to 18 hours. But when working with High intensity LED’s, the nutrient and water intake with certain plant families may be reduced slightly.
