outdoor use of grow lights ????
I have a wonderful vision of a shade garden full of tall ferns, solomons seal, hostas, caladium, trillium, lily of the valley, wild ginger, etc. I want to raise a two tiered bed, filled with 'perfect' woodland soil. My only problem is that, on the north side of my house, where this garden would be, the shade is deep...probaly too deep for the plants I want to grow. What I need to know is, could 1000watt metal halide FLOODLIGHTS provide the extra light I need? I know that indoors 1000w MH lights provide enough light for an 8ft X 8ft area. Would something similar hold true for outside depending on how I placed the lights? The floodlights are made for outdoor use and they have the same kind of buld as indoor grow lights. I'd deeply appreciate any info. The lights are expensive, so I'd don't want to totaly chance it.
