This is for growers who want to get serious.
The 2L Production Kit is the complete setup for anyone serious about a steady, ongoing supply of fresh spirulina. You get double the starting culture of our standard packs, plus the equipment and nutrient regime that turns a starter tank into a working farm. The aquarium pump and tubing facilitate gas exchange and keep the culture moving in and out of the light— the difference between a struggling vial and a thriving biomass. The post-harvest nutrients mean that once you start harvesting, your culture keeps producing instead of crashing.

Why the pump matters
Spirulina needs to keep moving in and out of the light. Still water limits growth and eventually kills your culture. The pump and tubing included in this kit keep your culture moving, healthy, and multiplying at the rate it should. This is the difference between a science experiment and a food source.
Why post-harvest nutrients matter
Some beginners kill their culture after the first few harvests because they don’t re-nourish the tank properly. The 1kg post-harvest mix is formulated specifically for cultures that are already producing — it replaces what you’ve taken out without shocking the system. This is the detail that separates a one-time harvest from a daily food source.
Why buy Australian
Imported cultures get seized by quarantine or die in transit. We ship express from Perth — no biosecurity paperwork, no roulette. You get a living culture that arrives ready to work.
Why fresh beats powder every time
Live spirulina retains 100% of its phycocyanin, B vitamins, and antioxidants — nutrients that degrade within hours of processing. The taste is mild and smooth, not gritty and fishy. And at a few minutes of care per day, it’s the lowest-effort superfood you’ll ever produce.
Frequently Asked Questions
How much spirulina will this make? Two litres is a serious starter volume. With proper aeration and nutrient management, most growers scale to a 100 litre working volume within 3-4 weeks. You can harvest daily from there. Potentially, you can grow 1000s of litres from just a few ml.
What if my culture dies in transit? Express shipping is included to prevent this. If your culture arrives unhealthy, we’ll replace it — you cover the return postage. We’ve shipped hundreds of cultures across Australia with a near-perfect arrival rate.
How long until I can start harvesting? You should be able to harvest around week 3–4, with the pump and nutrient schedule keeping production steady.
Do I need anything else? A clear tank or container and basic temperature control (room temperature is fine). We outline budget-friendly setup options in the manual.
How much daily care does this need? Less than five minutes. You check the basic conditions. Check that the bubbler tubes are affixed and the bubbles are doing their job, top up for evaporation, check on color and temperature.
What does fresh spirulina taste like? Nothing like powder. Fresh spirulina is smooth, mild, and slightly earthy — easy to blend into smoothies or juice. The “fishy” reputation comes from degraded, oxidised powder.
Can I use this outdoors? You can, but we recommend starting indoors where you control light and temperature. Once you’re confident, outdoor growing in a greenhouse or sheltered patio works well in most Australian climates.
What Growers Say
“I started with the 500ml culture and failed first time around. My bad. But Ken sent me a 1L replacement culture with lots of good advice to go with it. I built my culture up to 150L. I harvested my first 500g over the weekend. Ken’s manual is genuinely detailed, not just ‘add water and hope.’ I’m will now be able to supply my parents and my sister’s family too. This kit pays for itself in about two months if you were buying supplements before.”
