Testimonials

Sonia

Absolutely thrilled with my order from AquaCulture! Each product feels thoughtfully made, and the difference in my houseplants was almost immediate. They’re looking far perkier and happier already within just a week. The mist provides great coverage for larger plants.

Lucy Hayes

I’ve been using the aqua culture seaweed mist and fertiliser for a few weeks now and my plants are loving it!! I’ve had 8 new leaves this week alone (if that doesn’t prove how amazing it is I don’t know what does!) really easy to use and the people there are lovely 😊

Naomi

This is my third bottle of serum now and my plants love it. Since using this product I've repotted several of my house plants as they were flourishing. The product smells a little like the seaside but that is to be expected when buying a product made from seaweed... It comes packaged safely, and I've been able to recycle/reuse everything.
