Fertilizer for Greenhouse Growers

At JR Peters Inc. we understand that every grower faces unique challenges depending on what you're growing and where you're located.

Here's just a few to check out!

Jack's Professional 20-3-19 Petunia FeED - 

Specially formulated for chronically iron-hungry crops such as petunia, calibrachoa, bacopa and others. The original Jack's FeED product designed with all three iron chelates, EDTA, DTPA and EDDHA. Our proprietary blend of iron is unmatched and guaranteed to deliver iron at a much broader range of pH over the entire crop cycle.

Jack's Professional 22-5-16 Mum FeED - 

Mums are heavy feeders that respond well to additional magnesium, sulfur and iron. Many times though, the iron becomes unavailable as the pH rises. The elevated iron levels found in the exclusive FeED iron chelate system keeps the iron available to the plant even if the pH rises during the crop cycle. 

Jack's Professional 15-4-15 Poinsettia FeED CaMg - 

This product is designed to fit the needs of the newer poinsettia cultivars that require micronutrients, but a lesser amount of macronutrients. The specialty FeED package keeps iron available at a broader range of pH plus extra Molybdendum and lower B.  This formula is a Cal-Mag and should be used to supply extra Calcium and Magnesium.
