Spirulina Culture Nutrients

The minerals required for feeding your spirulina culture come in many variations, which you can read about in our glossary.

We have gathered here a selection of typical Spirulina Culture Nutrients being sold on Amazon and elsewhere. While quality may defer, we have done our best to hand pick the purest products available. For best results, we recommend ordering a grow kit with premixed feeds.

Whether you’re making the classic Zarrouk culture medium or a modified version like the Delhi mix, buying the materials in bulk and mixing your own will significantly lower your costs.

That said, we also included providers who offer complete, pre-mixed feeds so you don’t have to do any mixing yourself.
