Spirulina Nutrient Mix
The nutrient mix is different than the medium recipe. These RATIOS will work to make any amount of nutrient mix; in this case, the amounts reflect a target of 1.5 kg:
- Saltpeter (Potassium Nitrate): 1400g
- DAP (Ammonium Phosphate): 50g
- Potassium Sulfate: 30g
- Epsom Salt (Magnesium Sulfate): 20g
Mix well. The mix will keep for some time, as long as it stays dry.
If harvesting 2g of fresh spirulina, add 1g of nutrient mix. And, every 2g of nutrient mix or so, add a squirt of the iron we chelated above.
