Blazing Coco Premium 20 Pound Coconut Shell Charcoal Logs - All Natural High End Grilling

Would any ash from this product be compostable in the garden? I'm looking for that quality in my next grilling coal product...

Planning on using these for my wsm (22.5). any tips or tricks for longer cooks (e.g. brikset or butt) or shorter cooks (e.g. ribs)?

My intention for use is with an indoor grill. Is this product smokeless?

How many bricks come in the box?
