Okay, this is not at all my ideas, these ideas are all over the place, and common practice. But I'm writing this to help new comers have something to reference on how to use a still air box (SAB). First, choose a room to work in. DON'T use your kitchen or your bathroom. Those are the two dirtiest rooms in your house. A small linen closet or something with table of some sort in it, that can be easily closed off would be ideal. I don't have anything like that in my small house, so I use my bedroom. I have had no issues with contamination as of yet using that room, so I'm happy with it. Once you have chosen your room, you can set up. A hard surface is ideal, just for stability, but I use my bed. You want to soak a towel, then twist out all of the excess water that you can. Lay this flat on your surface. Now you will have to set up something to elevate your agar,cakes, or whatever you ate working with off of the towel. I use the rack from my PC on extra rings from my jars. At this point put the box in place and spray the whole room and inside the box with Lysol. Tip: Make sure any windows are closed, and there are no fans or air running. Start in the corner opposite the door, aiming at the ceiling, spray in a sweeping motion as you work your way back toward the door. Close the door, and let it settle for 10 to 15 minutes. *THIS IS IMPORTANT! YOU COULD BLOW YOURSELF UP! While you are letting the room settle, go take a shower you dirty hippy. After you shower, rinse with mouth wash. At this point, you can go in and get to work!
