Cloth For Hotbeds

Would cloth do to cover a hotbox to raise lettuce, radishes, etc., for
winter use where we get a very heavy rainfall?
Yes, if you make the cloth waterproof for its own preservation from
mildew and other agencies of decay. The following recipe for
waterproofing cloth is taken from our book on "California Vegetables":
Soften 4 1/2 ounces of glue in 8 3/4 pints of water, cold at first; then
dissolve in, say,
a washboiler full (6 gallons) of warm water, with 2
1/2 ounces of hard soap; put in the cloth and boil for an hour, wring
and dry; then prepare a bath of a pound of alum and a pound of salt,
soak the prepared cloth in it for a couple of hours, rinse with clear
water and dry. One gallon of the glue solution will soak about ten yards
of cloth. This cloth has been used in southern California for several
years without mildewing, and it will hold water by the pailful. Where
the rain is heavy and frequent, the cloth should be well supported by
slats and given slope to shed water quickly. Of course, this is only a
makeshift. Glass would be more satisfactory and durable in a region of
much cloudiness and scant sunshine; the greater illumination through
glass will make for the greater health and growth of the plants.
