Re: grow lights

I have 8 two tube shoplights, 4 feet long and have used both warm and cool tubes
over the years (sometimes in combination) but cannot see that the color of the
light makes a difference for me. I am only growing indoors until I can move my
vegies and flowers outdoors.
            My lights are adjustable in height using chains, but I have found it
much easier to use the type of foam insulation used in house construction. I set
out a flat that has just germinated with, perhaps, 8 sheets of this foam under it.
As the plants grow I slip the foam out from under the flat .. one sheet at a time
.. making, thereby, very small adjustments quite easily. My plants are never as
much as 4 inches from the lights.
        The foam is quite easy to cut to whatever size flats you use .. it is
surprisingly strong, 3/4 of an inch thick,  and it is feather weight. I have been
reusing my foam sheet/spacers for years. And, if you are lucky, you can get a
quite good supply for free from the scrap at a construction site.
        I can make small adjustments. Better still, I can vary the height of each
flat according to its rate of growth. I only use the chains for major adjustments
from time to time.
                                                                    It works for
me .......   Ed  Flynn
