The smaller Petite Fast Plant was compatible with this light box and planter. The Petite Fast Plant is advertised to reach the height of 7 cm (9.8 in). The height of the light box was 49.5 cm, the bulb drops down 3 cm, and the height of the planter was 20 cm leaving 26.5 cm for the Petite plant. It is expected that this will provide a better arrangement for experimenting.
