Our story
Tide & Thrive began with a simple idea from the team at Invigortex Ltd: gardeners deserve a seaweed feed that is honest, easy to use and goes a long way. We wanted one concentrated feed you could reach for across the whole garden, from patio pots and borders to the greenhouse and the allotment, without fuss or complicated routines.
So we kept it simple. One feed, one easy dilution of 2ml per litre of water, and a container that lasts. Everything we make is designed for gardeners, by people who love growing things.
From the Irish Sea
Our seaweed is harvested from the Irish Sea off the coast of Northern Ireland. We believe great plant feed starts with great seaweed, which is why we chose this coastline as the starting point for Tide & Thrive.
Cold pressed, made in the UK

Once harvested, the seaweed goes through a cold-press extraction process rather than high-temperature processing, keeping the natural goodness cold-pressed seaweed is known for. We then blend cold-pressed Ascophyllum nodosum seaweed extract with potassium humate and fulvate to create our concentrated liquid feed, made here in the UK.
Made for gardeners
Tide & Thrive suits flowers, fruit, vegetables, tomatoes, shrubs and houseplants, in containers, raised beds and greenhouse borders. Shake, measure, water in: that’s it.
