      • Whatever it takes to get the temps where you need them . I had the same prob, and now I'm shuffling a heater in and out depending on the weather outside. I need to get a heater that's thermostatically controlled.

        • I have a small grow room and my LEDs keep it at a perfect temperature during the winter. I worry a little bit about night time temperatures but I have never seen an issue.

            • I'm not sure what my grow room got to but our basement is usually pretty comfortable but we were down to 11 this morning outside.

              • i just like saving on AC bills. when my lights are on it brings grow room temps up nicely! i may not grow indoors when it gets hot and instead try to grow a single large plant outside during Summer hidden in-between Tomatoes

                • Same problem here. That's why the HPS's are still hanging. The new LEDs will go up in the spring.

                  • I wonder which is cheaper or more efficient to run, the HPS or a space heater?

                  • I have a small spacer heater in my grow room and I turned the exhaust fan down to 50% right now because I am just using the SF2000 over some seedlings.
