Here is the finer charcoal charging before I add to the beds.
a pump to charge the charcoal.If no pump is available the mix can be stired a few times a day.
I am going to keep trying to crush more and see how small I can get the pieces. Because our soil clay is very dense I don't think I need broken pots, I will make the charcoal chunky for air pockets. I will let you know how it goes and any interesting notable discoveries with the grocery store method. I still have a few more days to try to get it smaller. Now all I need is to find some more open bags so I can get a discount or better yet a free source of char. I would like to do a side by side comparison, but I probably wont, I remember back when I was I kid I used to charcoal at the bottom of my plants and the plants were lovely, I had a green thumb and didn't do much. Now it's hard for me to keep a house plant alive. I am going back to that method for house plants and will update the blog later.
Check out these experiments.
