How do they expect to get a decent crop with a set-up like that? The plants are spaced too widely and the lights are too far from the plant canopy. The lights look too low-intensity too. The only good practice I saw was lots of oscillating fans circulating air. Turn me loose in there and I could double their production overnight -- no harsh chemicals needed, no added expense except, maybe, better lights and more electricity. Doubling the crop would also require doubling the harvest crew. Or, as an alternative, halfing the space and overhead and the fixed and variable costs thereof while keeping the same production.
