The kit for growers who want it all in one box without breaking the budget
You have done the research. You know fresh spirulina is worth growing. What you don’t want is a weekend of running between pet stores and hardware shops trying to match a parts list.
This kit contains the essential items you need to go from unboxing to a thriving culture — living culture, nutrients, equipment, harvest mesh, and a manual that tells you exactly what to do with each item. We have assembled this from years of growing experience. The heater, the pump, the container size, the mesh specification — each component was chosen because it works with spirulina specifically, not because it is a generic aquarium product that happens to fit.
What is in the box
- 500ml Live Spirulina Culture — lab-verified Limnospira platensis, checked under microscope before shipping
- 1kg Fast Grow Starter Nutrient Mix — precision-formulated, makes 50L of media
- 10L starter growing container — clear, food-safe, the right depth for light penetration
- 50W aquarium heater — maintains temperature in the 28–32°C range spirulina prefers
- Quality air pump — keeps the culture moving
- Silicone air tube with suction cap — delivers bubbles
- Digital thermometer with probe — monitors temperature without disturbing the culture
- 500mm × 500mm harvest mesh — 44-micron mesh for clean harvesting
- Step-by-step growing manual — setup, maintenance, harvesting, troubleshooting
- 1 Replacement Culture — if your first culture fails through no fault of your own, we replace it (you cover postage)
- Direct email support — questions answered by someone who actually grows this
Why a kit instead of buying separately
You can buy the culture, the nutrients, and the equipment individually. Many growers do. But matching a heater to a container size, finding an air pump that does not over-agitate, and realising too late that your thermometer is not waterproof — these are the friction points that kill enthusiasm before the first harvest.
This kit removes the guesswork. Every component was tested together. The manual assumes you have exactly these items, so there are no gaps between the instructions and what you hold in your hand.
What to expect
500ml is a solid starter volume. Most growers reach an 80 – 100L working volume in 6–8 weeks, with first meaningful harvests around weeks 8–10. The 10L container included is your starting vessel. As your culture multiplies, you will expand into larger containers using the same equipment.
The 1kg nutrient pack makes 50 litres of starter media. When you begin harvesting regularly, you will need the Post-Harvest Nutrient Pack to replenish what the biomass removes.
Why fresh beats powder
Fresh spirulina retains up to three times more bioavailable phycocyanin, B vitamins, and antioxidants than dried powder. The taste is smooth and mildly earthy, not gritty or fishy. That “fishy” reputation comes from oxidised, degraded powder.
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 was going to buy everything separately until I added it up”
“I had a shopping list and was going to hit ebay but I still was not sure if the heater would fit the container or if the pump was too strong. I bought this kit on a Sunday afternoon, it arrived Wednesday, and I had the culture running by Thursday evening. The manual is genuinely excellent — it tells you not just what to do but what to look for when something is going wrong. Nine weeks weeks later I am harvesting daily from a 120L tank. The replacement culture guarantee was reassuring but I never needed it.”

Frequently Asked Questions
How does this compare to the Premium Kit?
The Premium Kit contains 1L of starter culture (double the volume), 1kg of post-harvest nutrients for replenishing after you harvest, and a pH tester pen. Choose the Essentials Kit if you want to start modestly and prove the process. Choose the Premium Kit if you want to reach harvest volume faster and have everything you need, including post-harvest replenishment.
How long until I can harvest?
You can begin expanding the culture immediately. First proper harvests usually occur around weeks 8–10, depending on light, temperature, and consistency.
Does this include everything I need?
It includes everything to start and grow your culture up to 50L. Once you begin regular harvesting, you will need the Post-Harvest Nutrient Pack to replenish what the biomass removes. It is also wise to obtain a pH tester to ensure the media is at pH 10 before harvesting.
What if my culture dies in transit?
Express shipping is included to prevent this. If your culture arrives unhealthy, we will replace it under the replacement culture guarantee (you cover postage for the replacement).
Can I use tap water?
Tap water is fine, provided you remove the chlorine. You can do this with an additive you can buy from an aquarium shop. You can also start with store-bought mineral water or filtered rainwater.
How much daily care does this need?
Less than five minutes once established. Check the bubbler, top up for evaporation, and monitor temperature. The manual explains exactly what to look for.
Is this safe to grow at home?
Yes. Spirulina grows in alkaline conditions (pH 10+), which naturally discourage most common contaminants. It is one of the safest home cultivation projects you can undertake.
What happens after the 10L container is full?
You expand into larger containers. The equipment in this kit — heater, pump, mesh — scales with you. Many growers move up to running a 100L container once they have the rhythm down.
