The Bambooloo™ Tamper-Spray is the best product for both wetting out the compost mass and adding microbial activity to it. The concentrate is also great for fixing systems that are too wet, and reactivating compost piles that have been exposed to harsh chemicals.
The washing wand is a bidet style accessory for split system composting toilets, used to wash down the pedestal during cleaning and/or to hydrate the compost mass.
