Definitely not for Autopot.

3 in the coffee product and the one at the end is control.

Very sick looking plants covered in spots and losing colour.

The one on the right is the control in potting mix.

Well I don't need to go any further with this experiment as you can see, unfortunately this exciting product had a chemical reaction the our own nutrient that dose not mean to say there is anything wrong with it and it could be a good soil enhancer but it is not for the Autopot system.
