Jack's Classic Reverse Osmosis Fertilizer

Reverse osmosis and pure water systems strip out essential minerals like calcium and magnesium that plants naturally absorb from tap water. This formula is designed to replace those missing elements, ensuring your plants get a complete nutritional profile without the interference of unknown minerals.

While it is excellent for hydroponics, it works perfectly for soil-grown plants as well, provided you are using reverse osmosis or pure water for irrigation. It is a versatile, complete feed that supports vigorous growth in any medium.

Yes, it includes a comprehensive blend of essential micronutrients alongside the 12-4-16 NPK ratio. This all-in-one approach eliminates the need for extra supplements, simplifying your feeding schedule.

Because it is a water-soluble powder, it dissolves easily into water. Follow the mixing ratios provided on the packaging based on your specific plant needs, and it can be safely used as part of a regular, continuous feeding routine.

The 12-4-16 ratio is balanced to support consistent, healthy development without overwhelming the plant. However, as with any fertilizer, it is best to start with a slightly lower concentration if you are feeding delicate or young plants to monitor their response.
