One thing I would pass on to those who are designing a new system is that you should have a minimum of three circuits, and plan for more than you expect.
Given loads are:
- Air Stone Bubbler
- Secondary grow lights for duck weed or Azolla
- Secondary air stone for duck weed
- Extra plug for a vacuum cleaner
- Tank lights
- Air vents or evaporation cooler.
- Room heater
- Deep fry
And even after planning for all of this you will probably find yourself adding new circuits and changing the locations of circuits after you begin using the system and discover better layouts, and stuff you never dreamed of.
It's been several months since I started using the grow room and many more circuits have been added. Contrary to safe building code, I have also removed the GFIs because they tend to trip at the worst possible times, like while I'm sleeping.
I have also added lights to indicate when a circuit is on. This makes it easy to see what's going on.
