This fine plant granulate consisting of pumice, expanded clay and zeolite like it very much. Gem. Ingredients it looks light and dark and can be processed well in its pure form or as an addition to easing / improvement of planting soil. Will I buy when you need it. Had it been tried with fine pumice, which I did not like so well. Addendum: have now seen that there is a similar product significantly cheaper under the name THEIS BiLaTon (10-liter bag)! I buy then the next time.
