  • Dark green-black liquid, filtered to 120µm microns (slightly more viscous than water). Microbially fermented for superior nutrient delivery.

    Natural separation will occur. Before use, shake or stir to resuspend the beneficials.

    Mixing: Seaweed blends with many products, but always do a small bucket test first to confirm compatibility.

  • IMPORTANT:

    Stir or shake container to agitate mixture and re-suspend particles prior to decanting for use.

    Add the liquid seaweed to spraying tank after water to minimise foaming.

    Dilution rate: minimum of 1:10L with water

  • Elise, Secret Garden

    “As a commercial flower grower, consistency and reliable flowering is very important to me. I used Channeled Atlantic liquid seaweed on my semi-cordon sweet peas this summer and found it to be a brilliant product. The plants remained very healthy throughout the growing season. The stem length and number of blooms per stem was also very consistent. I am very much looking forward to taking part in product trials in 2025, both for sweet peas and also dahlias and annuals.”

  • Jamie Hughes, Lyme Regis Golf Course

    “I've been using the fermented seaweed as part of my greens, tees and approaches programs for over a year now. The results have been fantastic on the turf and overall soil health. A cost effective product which enhances turf colour and builds up the plants defence system. I will continue to integrate the product into my program next season.”

  • Naomi, Mole End Plants

    "I met Dale a while ago, he is passionate about his product. We tried the seaweed plant feed alongside our usual fertiliser and found the results to be good. We like to use natural, local products so Channelled Atlantic fit well with our brand. As a business we are happy to recommend them to our customers. Thank you!"

  • Simon Berry, Organic Farmer

    “A top dressing of seaweed on my spring peas and barley has given the crop a real boost at the needed stage of growth.

    I would recommend this natural product for crops and I hope to use this more often in the future.”
