Description

Fish Bone Meal is a custom-graded, marine-derived phosphorus source designed specifically for flowering. Unlike standard fish bone meals that sit too close to regular fish meal in nutrient profile, this formulation has been ground to our own specifications — delivering higher phosphorus and roughly half the nitrogen of competing products, so plants direct energy toward bloom rather than excess foliage.

The nitrogen fraction is enzymatically hydrolyzed, providing a significant dose of amino acids, proteins, and hydrolyzed fatty acids alongside the core phosphorus and calcium feed. This makes it more than a simple P source — it's a broad-spectrum soil food that supports microbial activity and nutrient cycling through its organic carbon content.

Phosphorus, Calcium, Nitrogen, Amino Acids

Marine-derived phosphorus source, plus amino acids, protein and hydrolyzed fatty acid supply.

Mix 20–30 g per 5 L of soil when building your mix or preparing for flower. A slow-release phosphorus source — work it in early.

Soil people, same as you.

Soil Supply Co. started because we got sick of paying premiums for inputs that under-delivered. If we wouldn't put it in our own soil, it's not on the shelf.
