After harvest nutrient pack (1 kg) for Spirulina cultivation


Quality nutrient formulations to get things growing

Unlike gardening, cultivating Spirulina  doesn’t take a lot of effort. Spirulina is a very robust organism and basically looks after itself. However, while Spirulina is amazing it is not magic, you have to feed it to get it growing and after you harvest it to get regrowth.  Our nutrient starter and feeding mixes, free of heavy metals,  are formulated to give maximum growth. 

“I purchased 500ml of Spirulina from Ken at Spirulina Grow Co. I am so impressed with his extraordinary after sales service I felt compelled to write an endorsement. Ken really does go the extra mile in ensuring that you will be a successful Spirulina grower. He was more than willing to answer all my questions, his knowledge and experience is most impressive. I can thoroughly recommend Spirulina Grow Co, you will not be disappointed.”
