You don’t have to depend on commercial growers or expensive powders to get your spirulina fix. With this kit, you can have it fresh and alive, anytime. I made a few modifications to help mine grow faster and prevent clogging, like replacing the intake line with rubber tubing and swapping the bubble wand for a stone and filter. If I’d known it was so easy, I’d have done it long ago.
