We only sell the complete kit (i.e., no replacement media). The reason for this is that the media are by far the most expensive part of the kit in terms of both material and labor; for example, to ensure consistency, every single ingredient down to the vitamins and trace elements are precisely measured individually. The cube itself is not especially pricey, but should be replaced often anyway for two reasons: (1) The heat exposure weakens them over time, and (2) reusing the cubes and especially the spigot present significant biosecurity challenges. Because we guarantee success with these kits, we must be sure that clean, new equipment is used for every batch.Hey @Kenneth Wingerter
I am interested in growing my own Rhodopseudomonas palustris. I see you sell the homegrow kit but what about for subsequent batches? Do you sell the growth medium as a standalone product? Or is there something readily available we can use?
Not to say that the cubes can't be reused for other things; they're great for storing RO water or mixing kalk, for example.
