Your biggest problem will probably be biological--insects, fungus and the
other various nasties.

That'd be great, because the plants will be completely enclosed for
most of their lives. I notice that insects are completely baffled
by poly sheet.

Fungii, bacteria and viruses in the nutrient will be continuously
bombarded with UV-C in a stainless tub located in the base, so I'm
pretty confident that the nasties aren't going to be a problem.

I *am* still working on ventilation of both the growth column and
the 'leaf area' to provide CO2 to the leaves and 02 to the roots.

I don't suppose I could just pump the O2 from the leaves into the
growth column and allow the CO2 from the column into the 'leaf area'.

Could it be that simple? Hmmm.

Run the exhaust from your lawnmower in there. You'll have plenty of CO2, and
CO, and other stuff. d8-)

This is sounding an awful lot like some Frankensteinien experiment, Winnie.
Are you planning something really scary? Like a pumpkin with Republican
genes or something?
