My wife & i have grown fern's inside our home for going on 20 years now,growing indoors with artificial light is not an easy task & takes pratice,we use a combination of light sources,Metal Halide & High Pressure Sodium,these 2 light sources cover most of the color spectrum needed for healthy plants but they are not without major drawbacks like heat & high power bills.
Growers are now using LED grow lights to cover the blue & red color spectrum,we are thinking of adopting the new LED style lights but are worried,my wife has several ferns that would be worth close to $1,000 each if they were being sold at a nursery & we are afraid to damage or kill any plants by going LED.
Anybody use these type grow lights yet & if so how do they compare to HPS & MH growing systems.
