Hello, Do I have these items right? 1) To sterilize pots/flats use a 10% household bleach solution. (1 part bleach to 9 parts water) 2) To sterilize soil bake at 170F-180F for 10-20 minutes. 2) To sterilize seed coats use 1 tablespoon of household bleach to a gallon of water, submerse seeds for 10 minutes. Just want to check. Thanks, Tom
