The cheapest way to start growing your own superfood
This is the entry point. 50ml of living spirulina culture plus a full kilogram of starter nutrients — enough to get you from zero to 50L. If you want to try spirulina growing without a big upfront cost, this is where you start.
You bring a clear container, an aquarium air pump, and an aquarium heater if you are growing in cold conditions. We bring the life and the chemistry. The rest is in the manual.

What to expect
50ml is a small starter volume. It will grow, but it takes patience. Most growers build to a harvestable working volume in 8–10 weeks, with first proper harvests around weeks 10–12. If you want to harvest sooner, the 500ml pack gets you there in roughly half the time.
The nutrient pack included here is the same one used by commercial growers. One kilogram makes 50 litres of media. Free from heavy metals and contaminants. Food-grade formulation.
Why fresh beats powder
Fresh spirulina retains up to three times more bioavailable phycocyanin, B vitamins, and antioxidants than dried powder — nutrients that begin degrading within hours of processing. The taste is smooth and mildly earthy, not gritty or fishy. That “fishy” reputation comes from oxidised, degraded powder.
Spirulina grows naturally in alkaline conditions (pH 10+). This environment discourages most common contaminants, which is part of why cultivation at home is straightforward.
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, not a vial of regret.
“I started with the 50ml pack to test the waters”
“I wasn’t sure I’d stick with it, so I bought the smallest pack to try. That was six months ago. Now I’m running eighty litres, harvesting every week, and I haven’t bought a single supplement since. Ken’s manual got me through the early weeks when I had no idea what I was doing, and on the one occasion I emailed a question he replied the same day with exactly what I needed. If you’re hesitating because you’re not sure this is for you — start small. That’s what I did.”

Frequently Asked Questions
How much spirulina will this make?
50ml is a starter volume. With proper nutrients and conditions, it multiplies steadily. Most growers reach a 100 litre working volume in 8–10 weeks, at which point you can harvest.
What if my culture dies in transit?
Express shipping is included to prevent this. If your culture arrives unhealthy, we’ll replace it. We’ve shipped hundreds of cultures across Australia with a near-perfect arrival rate.
Does this include everything I need?
Almost. You get the living culture and the nutrients. You will need your own clear container, an aquarium air pump with tubing, and if growing in cold conditions, an aquarium heater. The manual outlines setup options and budget-friendly equipment choices.
How does this compare to the 500ml pack?
The 500ml pack contains ten times more starter culture and the same nutrient pack. It reaches harvest volume roughly twice as fast. This 50ml pack is for patient growers or those who want to test the process before scaling up.
How long until I can start harvesting?
You can begin expanding the culture immediately. First proper harvests usually occur around weeks 10–12, depending on your light, temperature, and consistency with the routine.
How much daily care does this need?
Less than five minutes. Check that the bubbler tubes are secure, top up for evaporation, and monitor colour and temperature. The manual explains exactly what to look for.
What does fresh spirulina taste like?
Nothing like powder. Fresh spirulina is smooth, mild, and slightly earthy — easy to blend into smoothies or juice.
Can I use tap water?
Tap water is fine, but it is heavily chlorinated, so you will need to add a dechlorinator – available at aquarium shops. You can also use store-bought mineral water.
