PyraPOD A4x4: while straight edge P4x4 is designed for DIY, this one will be made by professionals

Posted on

P stands for Pyramid, A for Arch. Curved edge and surface gives us more room inside than the one with straight edges on the top. This allows us to make the iAVS sandponics grow beds 10 cm deeper and have more spaces in between adjacent levels. The rest is the same as P4x4, its video is here: https://www.youtube.com/watch?v=39HLrFXHkxE Compared to P4x4, this A4x4 looks more like the Bermuda Buttery 🙂

Since obtaining PhD in Electrochemistry in 1994 (University of Calgary), I have been through many things, such as post-doctoral research work using STM to study atomic level electrodeposition of Cd on Ag(111) surface at UIUC (Urbana-Champaign at University of Illinois), lifetime free-lance preaching, CEO of TheoLogos Publications and PyraPOD Global Inc, former salesman of diamond tools for Superprem Industries, former director of DiaSolid Kitchen & Bath, finishing carpenter, working for CRE Green, a solar company in Kelowna, BC. After all these experiences, my life motto is this: sharp mind must combine with skilful hands. With my wife Margaret we have three kids - Riley, Grace and Anita.
