One near-sun greenhouse array has lost two growth cycles after a cooling lag destabilized the environmental rhythm the crop schedule depended on.
The event illustrates a recurring lesson from near-sun systems. Precision matters more than duration. The cooling failure was not long, but it landed inside a narrow part of the cycle where even a temporary thermal deviation made the growth plan economically useless.
That is why near-sun agriculture remains so unforgiving. It does not need a dramatic disaster to become expensive.
