The UVA can run the entire grow but I think that a waste of power. I run UVA the last 3 or 4 weeks lights on to lights off. UVB is a different story Last 2 weeks of the grow and for an hour or two Max in the middle of the day.What increments do you use when you first introduce the UV?
Do ya ramp it up or just hit it with an hour and watch to see if it can take more?
