I have started to plan and build a geodome greenhouse in our garden. Geodesic dome calculator - Acidome.ru 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…

I’ve also put the deckchairs in for this purpose, as I’ve spent a lot of time just sitting there over the past few days, taking in and enjoying the shape. Later I can watch the plants grow :wink:

it must be awesome in there under the rain !

I have started to close the gaps between the foundations… [image] Does anyone know of a narrow, transparent, UV-resistant adhesive tape that holds well on LDPE film, with which I can seal the seams from the outside (and which is not too expensive for the required length?!).

Cotty, I love your work! I’m jealous - wish I could have the space to do something similar. For your tape, I found this on Amazon, for repairing LDPE: [image] Amazon.com: GGR Supplies T.R.U. LDPE Heavy-Duty Greenhouse Polyethylene Repair... Ideal for polyethylene spicing; patching/repai…

Thank you! The tape is too wide and far too expensive for the required length over all the seams. I have started initial trials with a 25 mm wide glass fibre reinforced Tesa tape, which looks promising.

@Cotty , make sure to secure your fan fixed to the ceiling. 3D printing is fine but can you rely on it :100: % in the long run?

Finally installed and ready for the towers… [image]
