Geodome greenhouse with hydroponic towers

I have started to plan and build a geodome greenhouse in our garden.

I’m sure it will take quite a while, but if anyone is interested, I’ll report on the progress here. Of course, I have also drawn a first model in SketchUp so that I can plan some details.

There are also plenty of opportunities to use the 3D printer again. One that is currently causing my printer to run almost constantly is the idea of including 3D printed hydroponic towers in the greenhouse. A first sample has already been printed and is currently running without plants as a humidifier in the house.

I started here (Modular Hydroponics Tower w/ Grow Lights by Luitzor - Thingiverse ; https://makerworld.com/en/models/65860?from=search#profileId-78967), but many optimisations and new components have already been created.

The first plants, which will move into the tower when they have grown enough roots, have already seen the light of day…

Each of the 6 different boards must have two different angles on both sides when sawing. To avoid having to measure the cross-cut saw every time, I printed 6 templates that I can use to set the saw blade and find the right angles without measuring. The length is also written on each one so that you don’t have to have a plan next to it for every cut.

The first of over 100 triangles have been built and are covered with sturdy greenhouse film. I cover each triangle individually so that water that runs between them from the outside does not come into direct contact with the wood. Do you have any comments on this procedure?

I am planning three windows that will be fitted with automatic window openers that open the windows automatically when the inside temperature rises.

Two more to build …

This is like a story stick with saw guides on the end. A great idea.

Paul from geo-dome.co.uk seems to screw 3 triangles together before applying the plastic film.
Not sure if that has to do with waterproofing or if it’s an easier workflow…
I can’t find the video where he shows that.

Third prototype for the base of the tower in the lid of a black bucket with an integrated opening for refilling the water. I also made a template to mark the openings and holes in the lid of the bucket.
