No, its not an experiment, its a commercial operation, growing tens of
thousands of avocado trees each year. But this is the first time doing
the
etoliation (darkroom growth) on a large scale. That it works, and how it
works is established knowledge. Just sourcing the damn lights seems to be
a
problem.

I forgot to add that we grow avocado from seed in the dark (until the shoot
emerges) as a matter of course, thousands and thousands of the little
devils. By keeping them in the dark and at constant controlled temperature,
it reduces the germination time from several months to several weeks.

But this enquiry about the green lights relates to returning grafted
seedling (about 30 cm tall) to the darkrooms to clone additonal plants from
the grafted growth. Its all a bit space age, and I'm just a humble worker
in the whole process. It's very interesting work.
