I see that Leigh plans on heating his entire greenhouse with hot 
water. Is that what you are doing, Bob, or are you simply heating the 
benches, sort of a upscale version of the old 'hot bed.'? If that's 
the case, what are you doing to assure that you do not have freeze 
damage to starts, or is that actually a moot point with steady bottom 
heat? -Allan
