Scrach off the humidifier, you have no need for it. The rest of the items from Farmtek are okay. The main controller (heat, cool and whatever else it take care of) is a good unit as well as the controller for the misting system. No need for the rest of their stuff. In order to water, you can buy a small swamp pump from them, or can get it from Home Depot or Lowe's (around 130.00). This pump will pump your water to a hose to water your plants.
What kind of exhaust fans are you going to use? Very important to move volume of hot air out of the greenhouse and replace it with cooler air from your cool system!
I'm glad I don't need to deal with building a greenhouse anymore.
Ok, I've been doing more research and came up with this for an exhaust fan. How does this look for a 20x8x7 greenhouse?http://www.farmtek.com/farm/supplies/pr ... 09287.html
Between the two misting systems I have posted above, which one would you go for? With one of these systems in place then I wouldn't need an evaporative cooler (swamp cooler)? I am having the hardest time trying to even find one.
Heaters? Would I need anything special or just a couple plug in heaters would work when the weather gets cold?
Circulating fans? Overhead, side???
Accckkk... The more I research, the more I need.
