i understand if you want to keep info confidential but there's a number of people doing/did greenhouse setups though (commercial).
mary (seacrop) has pics of her setup on her website.
perrin's setup is 15+ years(?), although i heard he had a fire this year and hadn't seen it since then.
probably a lot of people doing private/individual setups.
currently, i'm doing a sunlight pico (2.5g) right now for NR's pico contest and had been thinking about a next gen project afterwards. e.g. 5.5g~10g, maybe a larger tank if i insulate my greenhouse (currently for plants not tanks)
i had been thinking of a directed-sunlight version, using a directional skylight device but i'm not sure if that product transmits the whole spectrum. this concept is more for built-in systems and/or more viewability for the tank (currently an issue i'm battling/mulling over).
anywho, i was just curious as how you had your setup done.
