Tom gave an awesome presentation! We had one of our largest meeting attendances for a GSAS meeting and the number of "guests" and new member sign-ups was significant!
Tom discussed several subjects including photosynthesis and how light, carbon, and nutrients can be manipulated to affect plant growth. My initial takeaway from that aspect of the talk was a light limited CO2 enhanced environment can provide good plant growth (not necessarily maximum growth) while minimizing the opportunity for algae growth.
