Heating a Water Garden? Answered
Im looking to start a water garden, i dont have much room in my back yard so i have decided on a 8 foot long trench thats about 6 inches wide with a pump to keep the water flowing. the only problem i am having is the growing season here isnt long enough to grow some of the plants that i would like to grow, i was thinking an underwater heater would be a good solution to keep the temperature above freezing and some what extend the growing season. Any thoughts on a good heater set up i could use that would keep the entire trench an even temperature without having to have a seperate heater every few feet?
