Most cycles allows the most chance for fertilizer input and plant up and out the door. The Dutch probably have this down really well as many plants grown fast and furious and to auction and not brought back. So, have to balance the media and everything else to allow fastest 'cycles' to allow most 'turns' or successive waves of plants through greenhouse = greatest chance of higher income. Many trade offs to manage as often the best growing media etc isn't the best for having short term plants or shipping them distance to warehouse or store, or keeping then alive once there. Good materials may be heavy and cost too much to ship. Also nitrates are chosen often for small plants on carts to stores because they can help to limit growth as tall plants take too much space on cart to store and hard to target proper sales shipping time if growing too fast and sloppy

This is why a lot of the "studies" don't apply to hobbyists. They are done under the study sponsors conditions to maximize profits, not healthy, long term orchid growth. Gettting the most effective "turns" is what everyone is after. It's what's the right way to do it that generates the discussions here.
BTW - shouldn't you change your name to MDCharles?
