Installing agri-grow lights is the perfect solution to the problem of insufficient sunlight in a greenhouse, particularly if the greenhouse is being used to grow plants for vertical and commercial operations. The winter months in Canada can be quite extreme and most parts of the country can go without seeing the sun for weeks at a stretch. Such lack of sunlight is dangerous for the plants in the greenhouse. Not only does it slow down or stop their needed photoperiod, but it could result in the death of the plants altogether. Commercial LED agri-grow lights are designed to produce light of the same spectrum that the plants can use to make their food and grow.
