Al Cairo, who in 2018 and 2019 together with the help of like-minded master gardeners built a Johnson-Su bioreactor in the Woodcock Demonstration Garden in Sequim, will present on Zoom on Thursday, 9th September.

The presentation in Cairo is part of the educational series Green Thumbs Garden Tips and examines the critical climatic realities of today and how gardeners can actively participate in the reduction of atmospheric CO2.

He will educate attendees about the soil food web and the construction and use of the Johnson-Su Composting Bioreactor to make a mushroom-dominated compost. This knowledge will enable gardeners to use alternative strategies for growing crops, eliminating chemicals, plowing and tilling the soil, event organizers say.

The zoom link can be found on the WSU Clallam County Extension website at or by calling 253-215-8782 (meeting ID 951 3978 9694, passcode 791808).

Cairo earned a bachelor’s degree in life sciences, majoring in optical methods and biotechnology from the New York State SUNY system. He worked for 27 years at the Roswell Park Cancer Institute in Buffalo and 13 years at Parke-Davis, Pfizer, Celera Diagnostics and Quest Diagnostics in San Francisco’s East Bay Area, in various areas such as tissue culture virology, electron microscopy, automated DNA synthesis and sequencing and liquid -Handling robotics.

Green Thumbs Garden Tips, sponsored by WSU Clallam County Master Gardeners, aims to educate home gardeners on research-based sustainable gardening practices in Clallam County.
