Grow mushrooms on old Digi-Key catalogs

Grow mushrooms on old Digi-Key catalogs via BB.

Making DIY gourmet mushrooms at home is difficult: you must buy a bale of hay, and must innoculate some sterile grain as “spawn.” That, or buy a pre-made “grow block” from a supplier. Instead, what if we use old phone books as the growth medium? Don’t throw out those Mouser and Digikey electronics catalogs, instead turn them into mushrooms. Pleurotus ostreatus (oyster mushrooms) is an easy one.

  1. Interesting idea, I felt a bit let down when I realised there wasn’t going to be a “here are some I prepared earlier!” section to the video!

    If you notice anyone follow his idea, please post it!

  2. i thought about using catalogs as enclosures

    cut out the middle and use a lot of glue

  3. Best patent that idea before another thousand people do it instead. Then you can extort sums of money from everyone else.

  4. A word of caution: some print processes use heavy metal drying agents in the ink. It’s possible that those could be picked up by anything growing in the paper.

    It might be a good idea to have a batch of mushrooms tested before anyone eats them, because mercury and/or lead poisoning sucks.

  5. Mike Stone is right. The ink used in these rotary printing processes is dangerous stuff. And mushrooms are notoriously known to their tendency to accumulate heavy metals and other toxic stuff. Thats why they are used as an indicator of cleanness of environment. i.e. in Eastern Europe after Chernobyl all the mushrooms were radioactive 🙂

  6. It has been done before actually, I saw, on some one grow psilocybe cubensis mushrooms on a bible, although those mushrooms are not “gourmet mushrooms” in the classical sense 🙂
