Hydroponics in cold weather, is heating needed?
 

Hi everyone: I live in KY. (USA)Is a greenhouse economically feasible after considering heating cost during the winter? I wonder if anyone farther north with a greenhouse could give me some tips on offsetting the heating problem.

Hello Kentucky You could use 1000 watt HID that would give off heat and supply your plants with more light that they need in the winter anyway. For most plants you could run the lights 24 hours a day.

To make winter time growing feasible it is almost essential to use some type of supplemental lighting. For wintertime operation the use of a small fairly inexpensive heating pad on which the plants sit can provide enough heat in an area where it will do the most good to make a significant difference providing you are not trying to heat a greenhouse in subzero temperatures.
