They are growing and growing. One big pepper and a number of small cucumbers. No zucchini and chilies yet.

The plants were moved onto some shelves. I lined the sides and the back with aluminium foil, for better lighting. Also added a fan to allow for some air movement (hoping this might help against vine louses).

Next step is to use the box on the bottom as a water tank to allow for automatic water refilling in the box. But I didn’t have the appropriate plumbing stuff yet.

Plants are growing like crazy :3

And there it is, my first small hydroponics system. Four plants in a deep water culture.

I used an IKEA 22l Samla box as a container. Might have gotten away with a the smaller 11l version, but the pots were quite big. If I get my proper net cups, I might build a smaller system in a 11l container.

The light is a 40W CFL daylight bulb, in an IKEA lamp shade. Hacked the stand, and used an old UPS as a counterweight. It’s on a timer, and provides 12h of light a day.

It’s standing at Munich Maker Lab, because I couldn’t find a place for it at home.

Air for my deep water culture. Using a 30cm Airstone, on a 165 l/h air pump.

Ebay seller didn’t deliever the net pots for my hydroponics system in time, so I used the pots which the plants came in. Let’s hope this works.

Repotting plants for hydroponics. Lot of washing, and still didn’t get all the dirt out. Well, should be good enough.

Building a Monome clone using a Trellis board from adafruit. Works great, just don’t quite like the LEDs yet. Need to do some looking around for other LED options, or hacks to make the LEDs have a wider angle.


Moar light!

Did some work on my CNC mill on Saturday. Finally hooked up all motors to the controller board, and then made the machine draw some stuff.

Still need to add some cooling to the stepper drivers, clean up the cable work, add a case for the electronics, and so much more…
