SEAFUEL · Seaweed · fish · humates
Feed it everything.
Three of the oldest inputs in growing — cold-water seaweed, fish hydrolysate and humates — in one bottle. SEAFUEL is the broad-spectrum fuel that carries plants from clone through flush.
Australian-made · 26 years in the US
Why it matters
Three inputs. One feed.
Seaweed, fish and humates each earned their place in growing over decades. SEAFUEL puts all three to work together, every feed.
Cold-water seaweed
Southern bull kelp extract, with its trace minerals.
Fish hydrolysate
A gentle, broad-spectrum source of nitrogen and amino acids.
Humates
Help hold and carry nutrition to the root — better uptake.
What’s in the bottle
Three inputs. One bottle.
Here’s what’s actually in it — read straight off the current bottle — and what each part does, clone through flush.
Durvillaea potatorum Southern bull kelp
A brown kelp from the cold Southern Ocean off southern Australia, carrying alginates and growth compounds for steady, even growth.

Thunnus maccoyii Southern Bluefin Tuna hydrolysate
Hydrolysed Southern Bluefin Tuna (fish hydrolysate). An allergen, and it rules out a vegan claim.

Humic acid Leonardite humic
Keeps minerals available so the plant takes them up efficiently, clone through flush.

What growers are seeing
Clone to chop.
“Roots and SWTNR for veg, Seafuel and Phat for flower — noticeably more colour and no signs of deficiency.”

Verified grower review
“Still using Roots and Seafuel in my cloning regime and they love it.”
@griffbain13
“Tried the Seafuel, Silica and Cal and the plants are praying — loving it.”
@yendofarms444
“Best yield and quality I’ve ever had adding the additives.”

Why growers switch
A plain salt feed vs. SEAFUEL.
A plain salt feed
✗
Just N-P-K salts.
✗
Nothing biological for the root zone.
✗
Feeds the plant, ignores the soil.
✗
One-dimensional.
SEAFUEL
✓
Seaweed, fish and humates together.
✓
Kelp, fish and humic acid in one bottle.
✓
Feeds the plant and the soil life.
