The light box was working so well, had two dozen seedlings, rushing to grow… I got a little over zealous about caring for my seedlings and I dropped a little too much into the tray, these are the results… oh human error.
After reading about NASA experiments where they found plants which could filter toxins (thanks wikipedia) out of the air, I became curious if these natural air filters, and if an ecosystem could run one of these filters. Of course automated data collection here would be really interesting, as a means of better understanding the results of the filter. Here is a proposal of what that system would look like in our 12th floor lab.
This prototype would feature a vertical garden using felt containers as a filter substrate and as a vehicle to grow plants.
