I need electricity for the hydroponic towers, possibly also for LED lighting, a fan, … That’s why I’m going to distribute several sockets all round, a first mounting bracket has already been designed and 3D-printed.

All 3 finished…
All the full hexagons are now built (6 normal, 3 with windows and one door element), 5 half hexagons and the pentagons are still missing.

To be able to control the radius and heights reproducibly, I hammered a stable steel rod into the ground and 3D-printed a rotation platform for a bar with a hole…

First point foundation as a test, the geodome will have 15 corners and all are to be supported in this way (with height equalisation).

The 3D-printed test towers are getting greener and greener, and the family is already snacking on them regularly

I have secured one of the first copies of his new book, hot off the press and signed by his hand. In addition to the many fascinating realisations of geodomes, it is also well worth reading because of the numerous eye-pleasing details and examples drawn with Sketchup!

To be able to explain the procedure to my future helpers when building the dome, I printed a model that can be assembled with magnets.

I have a new timer that has intermittent operation (x minutes on, then Y minutes off, infinite repeat). I accidentally programmed 5 minutes on and 55 hours off, it didn’t take a day for the plants to clearly show that they didn’t like it. (Now the cycle has been changed to 3 minutes on and 27 minutes off, does anyone have experience of whether this is suitable?)

Today I screwed the last triangle together and covered it with foil so that I could assemble the sixth and final pentagon, so that all the sub-components are now complete.
Now completed:
- Hexagon elements
- 6 hexagons
- 3 hexagons with window element
- 1 door hexagon
- 5 half hexagons
- 6 pentagons
- (6 of 15 foundations)

Four of the 15 point foundations still have to be poured, then the structure will be ready. Unfortunately, it has just rained, so this is still a little delayed.

All the point foundations concreted and the first of several customised raised beds built. I burnt the inside, I’ve read that this creates a natural protective layer for the wood (is that true?).
