From Greenhouse to Garden: Same System, Scaled

While Jack’s FeED products were originally formulated for a commercial greenhouse environment, the same nutrition logic doesn’t stop at greenhouse
scale. Iron availability, balanced fertility, and consistent micronutrient delivery are just as critical in a patio container or backyard garden as they are in a
finished greenhouse crop. That’s why the FeED system extends into the retail space through Jack’s Classic FeED formulations. Instead of changing the
science, the retail FeED line simply supports growth for the home gardener too.

Petunia FeED supports high-performance flowering plants where color,
uniformity, and continuous bloom matter most. Think baskets, porch pots, and
garden annuals that need steady feeding to stay in peak display.

Veggie FeED is designed for the vegetable garden plants, where consistent
nutrition translates directly into overall crop health, from transplant to harvest.
20-10-20
Citrus FeED targets citrus and fruiting plants that demand steady iron
availability and balanced nutrition to support both vegetative growth and fruit
development.

The foundation stays the same: complete fertility with a stabilized iron system.
That’s the thread that connects the entire Jack’s FeED system. Different crops,
different environments, same nutritional focus.
Good fertility isn’t about reacting to problems—it’s about preventing them from
showing up in the first place. GRIFFIN GAZETTE 20 26 | 33
