I am about to put this together and wondered your opinions before I bother. (not that it will take too much effort) I'm in Ohio which has already had single digits F. this FALL even before winter. I have a great South facing window nearly 4' x 6 foot tall. Lots of sun but even though double pane glass gets a bit cold near the window. Low 60s and maybe colder as I only measured once. Tropical shivers.
Trees are doing okay there but wanting to rebuild shelves anyway so considering building this tray with a waterbed heater underneath the aluminum pan with about an inch of sand in the tray to help hold the heat. Placing the probe in the sand for the thermostat which can be set as low as 70 degrees F. The runoff from watering would also help the low humidity of our forced air heating. This would end up being just under 4 foot long and about 16 inches wide. The width of the window
I know I'm not a pioneer as I read they are often used for seedlings and such but thought my tropicals might enjoy it. I'm not buying this stuff either, just using what I have laying around the house.
Worth the bother? WhaCha Think?
