Indeed, 300 bf is best for ash to achieve the whitest color when starting with green lumber. If air dried first, the 1000bf is ok.
For shorter loads, baffle the holes so that all the air goes through the lumber pile.
A closed kiln without lumber can indeed reach 200at the peak of the roof. With lumber in it, you might reach 30 to 40 F above outside, but even if the air is this hot, the lumber internal temperature will not reach 133 F required for sterilization.
A solar kiln does not get hot enough for sterilization.
Due to its poor energy efficiency- -the clear roof- -you would need to get a separate building with a separate heater. If you use a solar kiln, with auxiliary heat and the collector covered with insulation, the heat might affect the fans and building components.
