I needed, at this time, a couple of small green houses that I could mount on two of my work tables.  I have trouble bending over, because of a bad back and these green houses on top of these spare work tables works really well.  My tables are 28  inches deep and 8 foot wide.  These green houses cover about 1/2 of the table and I use the other 1/2 as a gardening work area.  This works out really good.  Ron Zalewski
