They use of a different mechanism to power it by delay. They use a second CO2 fixation pathway known as Crassulacean Acid Metabolism (CAM). Basically they "store" the energy by day, then open up at night and to their thing. Only 5-6% of plants do it this way and, IIRC, almost all of those are succulents or desert plants. This pathway helps preserve water. https://en.wikipedia.org/wiki/Crassulacean_acid_metabolism https://en.wikipedia.org/wiki/Crassulacean_acid_metabolism is a decent introduction to it. Also, most "kid" bedrooms are around 10x10 or so, but some master bedrooms can be rather ... large. I said 3-4 to cover both not being the only one in there and the size of the plants. The tests are done on or projected to full-size mature plants, but if you go to the store and buy them they are rarely full size. They'll range from 6-8" babies to about 1/3-1/2 in size (1-2'). For the "full effect" from the reports they size based on a 4' tall plant.
