Good posts on THC Richard, just went for a look. I'm not sure you'll get sense from there though they just seem pleased with themselves and your query may go over their head.
I've worked out yield based on the "agm presentation" its slightly more generous then yours above but close.
1 machine = 3.175kg per 60 days average 6 harvests a year. 3.175*6=19.05kg per year for one machine, or as presentation stays 240 machines = 4570 per year. = 19.041 per machine p/a (round up to 19.05kg/pa)
therefore to achieve 37000kg based on RGI tech we need 37000/19.05= 1942.25.. machines to get the job done
each machine takes up 32sqf = 625 machines with no space on 20000sqf
Stacked 4 high, with 500 on the bottom level that would leave 125sqf for some exceptionally skinny walkways, or maybe they go even higher? their subsidiary is called "Verticann" maybe that's why?
