Since PyraTUNNEL is so similar to the Linum greenhouse built in Norway 2012, I have gathered all videos I can find on the project and display here. Note that in our most updated design of PyraTUNNEL, sandponics is added to it, which was missing in Linum project.
BTW, the Linum project is still operating but we have not seen anything published so far, which is sad.
