A premium blend of pH controls and pure mineral salts, Europonic®Rockwool Conditioning Solution™ is ideal for pre-conditioning rockwool cubes and stonewool growing media products before starting seeds, clones and transplants.

Most rockwool is naturally alkaline, and manufacturers recommend preconditioning in a mild acid solution prior to use for proper pH levels at the root zone. Europonic Rockwool Conditioning Solution has been formulated specifically for this purpose.

How to Use Europonic Rockwool Conditioning Solution

General Use – Shake well before using! Add 3 ounces of product to each gallon of water used to condition cubes and mix thoroughly. Next, completely saturate cubes and let soak at least 2 hours. Drain any excess and then plant or transplant seedlings.
