Second thanks on the sulfer evaporator info, Doc Bud. There's nowhere in the literature that gives times; I thought 3 hours in a grow closet would be good enough seeing how small the cubic area is. That would explain the quick comeback of the mold. I'll do it again tonight for a full 6 hours. I can't get my humidity higher, but I'll mist all these plants before lights out.
If you're in a tent, just go down to Rite Aid and buy el cheapo humidifier and that will do that trick! The humidity really makes a difference.
