I actually use this as a preparation a few hours before I start my process. Having animals can make things tough. I dilute into distilled water and pour into a humidifier in my clean room and allow to circulate for several hours before starting. Then I wipe everything down really well with alcohol. I have never once had a contamination or mold issue. At least twice a week I use in my grow area.
I run this every other tank fill up and it shows great results. I swear it helped one my blocks to fight off a minor spot of contam.
Been struggling with slime build up on my Greenhouse humidifier and this stuff worked within 24 hours! Love that it is safe for everyone also. Has a faint hotel pool smell that I actually enjoy! Haha
Regarding package including ant--bacterial solution, pre-filled agar dishes, and a coir block. I have not used the products yet, but the package and products arrived in excellent condition and, I think, within 36 hours of ordering. I am very happy with customer service's speed of delivery.
