I do both here , depending on the customer that purchases it from me ,
but generally just use a reputable soilless mix and grow them in propagation flats for shipping to customers but those trays are placed into hydro tables !

All grown under a sellection of lights , from 400w , 600w and 1000w bulbs and both metal halide and high presure sodium !

Growth is fast ! and produce any where from 150 - 200 trays a month ! in a fully monitored indoor greenhouse !
