WebThis was possible only in the "open" experiments of 1931-1934 in Petersham (Pkaes 5 and 6). Under the Môller house in the 1930 experiments (Plates 3, 4 and 5) the glass roof would prevent radia- tional cooling of the plants outside the water-filter. To this extent the experiments in 1930 provided controls lacking in the 1931-1934 experiments. WebFlexBook Platform®, FlexBook®, FlexLet® and FlexCard™ are registered trademarks of CK-12 Foundation.
