In Ep 022, Aaron announces he purchased a Clean Light after it was discussed in a previous episode. Bubbleman cautions him not to declare victory too soon, saying he needs 6 months of data before claiming it works. Remo reportedly also uses one. Bubbleman notes Johnny B's grape vine outside his grow room harbors massive amounts of mildew, joking he would need a hundred Clean Lights for it.
