Yeah, they don't actually increase the PAR on HID lamps but they do on fluros. However, what does PAR have to do with plant growth? Someone mentioned earlier that "it may appear different on camera, but it doesn't look that way in my grow room".Thanks for the clarification Cues.
I thought it had something to do with the wave lengths but I'm not an expert when it comes to lighting and unlike others on this forum, I don't pretend to be.
I think digital ballasts increase PAR as well, perhaps that also has something to so with it, I don't know.
All I care about is the fact electronic ballasts run cooler, are more efficient and give out more light.
The point is, it may not look that way to him but how does it look to the plants? They don't have eyeballs and brains that can't keep up with the flickering so try to compensate so they don't get a headache. If my £20 digital camera can sense it, I'm sure the plants can.
I think what is needed is a side-by side grow with one digital and one magnetic ballast. Shared res and everything.
