this seems kinda cool.
Growth Under Metal Hailide and Microwave Powered Sulphur Lamps
Appearance of 'Poinsett' cucumber plants grown for 14 days in a growth chamber under six 400 W metal halide (MH) lamps and under a single 1000 W microwave powered sulphur plasma lamp (MPS).
Note space between MH grown plants and the absence of space between MPS grown plants and the fact that pot labels are still visible among the MH grown plants but not the MPS grown plants.
