Hereā??s the 2 types of tape I was talking about. On the left, silicone Stretch & Seal, made by Nashua. On the right, your typical crappy electrical tape, that separates itself from itā??s adhesive after a week.

My heat lamp underneath my germinating seeds. The shelf is from a Raid insecticide display from the same Bimart. I snagged 2 of em for $5 each. Right place, right time.

The unit installed, along side the Green Air atmospheric controller. I know, a lot of friggen cords. Did I mention I was remodeling, still?

Hereā??s how the package works: The heat lamp is plugged into a repeating cycle timer, which is set to 3 minutes on and 12 off. I just didnā??t want it too stay on real long and melt something. The timer is plugged into my newly assemble thermostat, which is plugged into the side of the Green Air controller that is normally on. The new thermostat is set to 81, which means the timer starts to get power at 71 or below, and continues to have power until temperatures reach 81. The Green Air controller is set to 83, which means thatā??s what temperature will turn off the power for the timer and heat lamp, and turn on the power for the exhaust fans. The controller is designed for exhaust to stay on until there is a 7 degree drop in temperature.

The reason itā??s so elaborate is because I wanted to make sure that both the heat and the exhaust werenā??t on at the same time, and that the heat lamp didnā??t burn down my house. I should mention that you canā??t just set these things to whatā??s marked on the dials and hope everything works out. Youā??re going to have to do a little testing and adjusting based on where they are positioned, and where fans and lights are, and the canopy is. I highly recommend passing a laser thermometer along your canopy while you are testing, and trying to keep things at 80 degrees. You should pay close attention during at least one complete heating and cooling/exhaust cycle to make sure everything is operating according to plan.

Hope you like. Comments, questions and criticisms are all welcome. Also, Iā??m not an electrician; use your best judgment.

PS. My seeds are sprouting after 40 hours.

Cheap and Easy Thermostat You donā??t have to spend $200 or $300 for a fancy name brand ā??atmospheric controllerā? to regulate the temperature of your grow area. I rigged up a simple thermostat and heat lamp to keep my seeds warm during germination, which comes on if temperatures drop to 71. It stays on until 81, but just too make sure things donā??t get too hot too fast, it has a duty cycle of 3 minutes on and 12 off. Additionally if temperatures reach 83, an exhaust system with a big-ass, room clearing fan comes on, Rating: 5
