Highly concentrated, fully Organic, 1-part liquid nutrient

The first and only complete certified organic nutrient for all substrates

With a pedigree dating back to 2004, Pro Organic has been in commercial use around the world for years, including by our partners Les Sourciers. Pro Organic is a practical and incredibly effective way to feed your plants organically, for hobby growers and professionals alike. Pro Organic formulas are specifically designed to meet the needs of all plants throughout growth, flowering and fruiting.

We base our formulations on ecological principles that maintain respect for the environment whilst providing plants with balanced, effective nutrition. Pro Organic actively improves the root environment by feeding microbes that live in harmony with your plant. This provides the essential nutrition and environment to deliver healthy vegetative growth, flowering and fruiting.

Pro Organic is ideal for every type of plant and will work wonders as a standalone product: when we say “complete” we mean it: you don’t need additional elements for a successful, bountiful grow, in most water*.

Pro Organic is perfectly soluble and well adapted to automatic and drip irrigation systems, or hand watering in conventional gardening. It is also the only nutrient certified for Bioponics (bare root recirculating organic hydroponics). See Bioponics feed chart.

To improve performance even further, and to give gardeners more flexibility to optimize their grows, the General Organics line also includes a range of complementary organic additives and we also sell the high quality beneficial microbes you need to make organic gardening work without rich soil.

This nutrient is produced according to one  formula – however for this product, values are declared in chemical elements in South Africa/Australia and in oxides in Europe; which leads to differences in labels.

How to use Pro Organic:

Pro Organic is very concentrated: a maximum of 2 ml/L in water is enough in soil or hydroponics.

Shake bottles well before each use, add each part to water separately, mix thoroughly, and always rinse measuring equipment.

Please note: Pro Organic (and all organic feed) must be broken down by microbes to be made accessible to plants. For a colony big enough to do this to develop, especially early on in a plant's life, a biofiltering system working 24/24h must be added to the tank in both drain to waste and recirculating systems.

Biofiltering systems be purchased in your local shop, or made by suspending a plastic basket (3 to 5L) filled with 60% clay pebbles and 40% coco over your tank and running water through it continuously. If using our GrowStream® system this can be done under the return pipe.

Do not immerse filter systems in the tank as high oxygen levels are vital for rapid growth of beneficial microorganisms.
