There are fewer daylight hours in the winter. Grow lights provide the full spectrum of light, which helps prolong the hours of light for plants to grow.
What Happens When You Leave Your Grow Lights On 24/7?
I’m a new grower, 17 (on) & 7 (off) is one of the typical “schedules” I highly recommend for grow lights. I assume the purpose of this is to mimic a natural cycle of day and night, but I’ve often wondered what would happen if you grow plants under nonstop sunlight. Is it a poor plan? Thanks!
