Table-Frame heatersI bought a pair of 150W/120V heaters a month ago to use in a pair of 'Table-Frame' boxes I built to keep seedlings in my greenhouse from getting too cold at night this time of year. 1 heater in each box with a small fan in the left one to circulate warm air. A dual temperature switch via PLC control runs these alternately and with a variable duty cycle (I don't want to cook the seedlings, just keep them between 45-50 degF overnight).
