People frequently believe that UV lights should only be used during the flowering period because they are beneficial for flowers. But if plants don’t thrive throughout the seedling or vegetative phases, how can you hope for a higher yield?
Donc the earliest stage of plant growth is the best time to begin applying UV lights. There must be at least two hours of UV light per day. If you use grow lights to cultivate your plants, you must ensure that UV light does not exceed 2 ou 3 watts in intensity.
During the seedling and vegetative stages, you should apply UV light for a short period of time, such as an hour. When the plant has fully grown, extend the duration to 2 heures, and increase 15 minutes day by day. Keep an eye on the plant’s condition. If it’s burning, stop; sinon, add more.
