Well almost all my pots and trays are disinfected. I use the 4 ft kids pool for bleach water, put a bunch of pots or trays in the pool all at once- soak 10 to 15 min, take them out and put in more pots or trays, this is a 2 day job or more.
My potting mix box is made out of an old maple syrup pan (6'x3'). I put in all my ingredents (dry) mix up by hand then add water and mix by hand again, ready to sow. When I'm done planting for the day I cover the box with a cut to size piece of plywood, now I have a work bench.
