Here's what our customers have to say:

Hello Frank,

I managed to do my first burn on Monday. I didn't have a permit but I felt that the rain would've made the chances of the fire spreading very low.

I was very surprised at how well the burn turned out. I had watched the youtube video to get hints, so I knew that the time to dump more garden waste was when the top of the charcoal was getting white.

But considering this was my first burn, I knew that the chances of getting a perfect result were slim. I was also dumping grass clippings and other small sized garden waste on it too, and knew that this would restrict the airflow.

I filled it up with water from the bottom valve. Once I began to see the water on the surface I turned off the valve began spraying the top and then filling it up to the top. I left it overnight. The water draining out was dark rather than clear but left bubbles along the way, indicating a level of soapiness from the ash.

After it had drained fully I checked inside deeply and was very satisfied with the amount of charcoal created. There were obviously some partly charred sticks among it, but far less than what I expected.

For my next burn I'll start off using the charcoal created and make a very hot fire before throwing more garden waste on. That should result in the partly charred biomass getting fully charred.

But overall I am very satisfied, and look forward to developing expertise in the process. I'll also be looking to train my wife in cutting the garden waste into smaller sections.
