Hydroponics


About

Not sure where this idea came from, probably from some random online video of a warehouse doing hydroponics on an industrial scale. The concept isn't difficult, just run fish water through a flower bed, I can do that.

It started with a smaller 25 gallon tank, where the goal was only to keep fish alive and have it self sustaining. Took a lot of work but eventually it got there (aside from water changes, those still required supervision and manual flipping of switches) and many lessons were learned. With the pilot run out of the way, it was time to build this version.

Components

Here's a rough rundown of what all was used.

  • 40G breeder tank, as the display
  • 20G tank, as the sump
  • ECO291 water pump, to circulate water
  • 20ft of 3/4"ID hose
  • 5x 3/4" bulkheads
  • 3x Outlets
  • Lots and lots of wood
  • NodeMCU, control the lighting and pump
  • 5M White led strip
  • 5M RGB led strip
  • Ultrasonic sensor
  • Temp sensors
  • Other misc components
