The sherbinski tent is vegging along. To apply STS to only one plant without removing it, I'm using a cylinder of reflectix around the chosen plant and turning off all fans so I'm only treating.the one. I don't think there will be any exposure to the others. Removal for treatment involves unhooking from irrigation. Seems like unnecessary work. Back right is the chosen victim, Gorilla Frost in front of it definitely catching up with the others.
