Peters Professional STEM is the original, industry standard water-soluble micronutrient supplement that provides the all-important "quick fix" nutrition.

A fully water soluble fertilizer and broad spectrum minor element product that is ideal for "quick fixes" on ornamental plants. Can be used for corrective purposes on micronutrient deficient crops. It can also be applied as a remedial foliar spray on ornamental plants like: potted tropical foliage, flowering plants, cut flowers and orchids.

Benefits

  • Customizing component suitable for use with a variety of base formulations
  • Contains a full range of essential micronutrients
  • Effective for all water types

How To Use

  • 1. Consult rate tables printed on bag.
  • 2. Verify product analysis, longevity and rate for plants in your production system (for assistance, contact your regional ICL-SF Territory Manager or call the ICL Lab at 877-467-8522).
  • 3. Fill tank with water to approximately 1/3 of full volume (use warm water if possible, to dissolve the fertilizer faster).
  • 4. Add mineral acid if necessary (may be required with alkalinity levels greater than 250 mg/l calcium carbonate).
  • 5. Add STEM and mix vigorously.
  • 6. Top off tank with water.
  • 7. A product trial is recommended before adopting a new fertilizer program or making full-scale changes to standard cultural practices (test several rates on representative plant types).

What does Peters Professional STEM do, and what kind of plants is STEM designed for?

Peters Professional STEM is a fully water-soluble micronutrient supplement designed to deliver a broad spectrum of essential minor elements as a quick corrective fix for micronutrient-deficient crops. Peters Professional STEM is especially suited for ornamental plants including potted tropical foliage, flowering plants, cut flowers, and orchids, and can be applied as either a soil drench or a remedial foliar spray.

Which micronutrients are included in Peters Professional STEM, and at what concentrations?

Peters Professional STEM contains a full guaranteed analysis of essential micronutrients: 13% sulfur, 8% manganese, 7.5% iron, 4.5% zinc, 2.3% copper, 1.35% boron, and 0.04% molybdenum. All iron, manganese, zinc, and copper fractions are fully water soluble, and Peters Professional STEM contains no nitrogen, phosphorus, or potassium, making STEM a pure micronutrient additive rather than a complete fertilizer.

Can Peters Professional STEM be used with different base nutrient lines and water types?

Yes, Peters Professional STEM is formulated to work as a customizing component alongside a variety of base fertilizer formulations and is effective for all water types. Growers using water with alkalinity levels above 250 mg/l calcium carbonate may need to add a mineral acid to the tank before mixing in Peters Professional STEM.

Is Peters Professional STEM suitable for hydroponic systems as well as soil growing?

Peters Professional STEM is approved for use in both hydroponic and soil nutrient programs. Because Peters Professional STEM is an inorganic-based powder that is fully water soluble, STEM dissolves cleanly into reservoir or tank water for use across a wide range of growing systems.

How should Peters Professional STEM be mixed into a nutrient tank?

To mix Peters Professional STEM, fill the tank to roughly one-third of its total volume with water, using warm water when possible to speed dissolution, then add any required mineral acid, add Peters Professional STEM, and mix vigorously before topping off the tank. Consult the rate tables printed on the Peters Professional STEM bag for application rates, and Peters Professional recommends running a product trial on representative plant types before adopting a full-scale program.

Is Peters Professional STEM an organic or OMRI-certified product?

Peters Professional STEM is an inorganic-based fertilizer and is not OMRI certified. Growers seeking a certified organic micronutrient supplement will need to look at alternative products.
