How lucky you are to have a green house. i am almost envious, almost.

I am reminded of the back breaking Fylde horticultural post war, perhaps pre war industry that ran on a 3 crop year long production of steam heated greenhouses growing chrysanthemum for xmas, tomatoes for spring \early summer & lettuce for summer & autumn. A big farm was half an acre.
Here in Australia half an acre is merely the septic tanks & soak aways or the scrap vehicle yard. Greenhouses are more likely to be 100m x 20m and plastic is used rather than glass though more often than not there is no need for the shelter & heat of greenhouses bird & bat netting is used instead.
A local organic horticulturalist growing asparagus, broccoli & broccolini, tomatoes and heritage potatoes tripled his crops by simply buying & using construction site fencing around his 100m long beds. It not only kept the kangaroos off the seedlings but has become an advantageous watching & launching post for the magpies, crows, @kestrels, kookaburras & owls catching rodents & rabbits. Smaller birds probably also use them whilst waiting for insects & moths.

You thought of Hydroponics which will allow you to keep the plants watered and fertilised and enable you to cram more plants into a small area?
It would also suggest vertical gardening so that every milimetre of space is utilised to it's fullest potential.
In such a fine structure you may be able to do all forms of gardening

Will the congregation enjoy automatic aspergillum?

WONDERFUL structure!

That is wonderful!! You have some good friends!
