effective chelating system that dissolves faster, resulting in improved plant performance
Jr Peters professional fertilizers
20-3-19 Petunia FeED
Formulated for plants that do not take up iron efficiently in the root zone.
Contains an enhanced micronutrient package that will produce lush
green plants in any growing condition. Perfect for iron-hungry plants
include: petunia, calibrachoa, bacopa, verbena, vinca and salvia. Lowphosphorus
formulation keeps plants fuller. Petunia FeED is especially
effective in hanging baskets and containers that are watered often. NO3:
11.96%; NH4: 8.04%; Urea: 0%; EC per 100 ppm N: 0.64 mS/cm; 100
ppm N @ 1:100: 6.75 oz/gal conc.; 1 level tsp/gal = 250 ppm N; CCE
= 420/lb CaCO3
27-15-12 Foliar Feed
Specially formulated to use for foliar feeding of ornamentals, vegetables
and fruits. High urea content and micronutrients promote green-up and
foliar expansion. Can be used in conjunction with normal media fertilization
or alone. Addition of a surfactant enhances activity. Perfect for field and
high tunnel grown fruit and vegetable crops. NO3: 3.71%; NH4: 2.96%;
Urea: 20.33% EC per 100 ppm N: 0.22 mS/cm; 100 ppm N @ 1:100: 5 oz/
gal conc.; 1 level tsp/gal = 338 ppm N; CCE = 923/lb CaCO3
20-20-20 General Purpose
Great for maintaining plants in garden centers and growing facilities.
Provides fast green-up and great foliar expansion due to the high
percentage of ammonium and urea nitrogen. Balanced phosphorus
and potassium for excellent root and shoot growth. May be used on all
outdoor grown plants. NO3: 6.07%; NH4: 3.83%; Urea: 10.10% EC per
100 ppm N: 0.42 mS/cm; 100 ppm N @ 1:100: 6.8 oz/gal conc.; 1 level
tsp/gal = 250 ppm N; CCE = 555/lb CaCO3;
20-10-20 General Purpose
Has the traditional micronutrient levels needed for general production
including propagation and all types of bedding plants. High nitrate
nitrogen levels (60% of the total) provide for green foliage and more
compact growth. Can be used on all plants. NO3: 12%; NH4: 8%; Urea:
0%; EC per 100 ppm N: 0.64 mS/cm; 100 ppm N @ 1:100: 6.8 oz/gal
conc.; 1 level tsp/gal = 250 ppm N; 07-5918; CCE = 407/lb CaCO3
25-5-15 High Performance
High-efficiency formula. Designed to maximize your NPK delivery while
keeping a balance of macro, secondary and micronutrients for optimum
plant growth. Best as a continuous feed for heavy feeding plants in
moderate to warm temperatures. Micronutrient levels are comparable to
peat-lite formulas. NO3: 14.25%; NH4: 10.75%; Urea: 0%; EC per 100
ppm N: 0.57 mS/cm; 100 ppm N @ 1:100: 5.4 oz/gal conc.; 1 level tsp/
gal = 312 ppm N; CCE = 608/lb CaCO3
9-45-15 Plant Starter
Use Plant Starter when transplanting into cells or beds. Highphosphorus
ratio boosts root growth prior to shoots. Can also be used
in outdoor production where soil tests indicate phosphorus deficiency.
Perfect for field-grown vegetables. NO3: 0%; NH4: 9%; Urea: 0%; EC
per 100 ppm N: 1.20 mS/cm; 100 ppm N @ 1:100: 15 oz/gal conc.; 1
level tsp/gal = 113 ppm N; 07-5935; CCE = 965/lb CaCO3
21-7-7 Acid
Ideal formula for acid-loving plants. Jack’s Acid provides a rapid
correction of high media pH. Unlike other brands, Jack’s Acid contains
no harmful chlorides. Excellent for rhododendrons, azaleas, and
evergreens. NO3: 0%; NH4: 11.47%; Urea: 9.53%; EC per 100 ppm N:
0.60 mS/cm; 100 ppm N @ 1:100: 6.4 oz/gal conc.; 1 level tsp/gal =
263 ppm N; CCE = 1,539/lb CaCO3
20-10-20 Peat-Lite
A traditional 2:1:2 balanced ratio formula with a 60% Nitrate to 40%
Ammoniacal Nitrogen balance. Delivers approximately twice the level of
micronutrients as the GP formulation. Additional level of micronutrients
provides necessary elements absent from most commercially-made peatlite
potting media. May be used on all greenhouse plants grown in peatlite
mixes. NO3: 12%; NH4: 8%; Urea: 0%; EC per 100 ppm N: 0.64 mS/
cm; 100 ppm N @ 1:100: 6.8 oz/gal conc.; 1 level tsp/gal = 250 ppm N;
CCE = 401/lb CaCO3
15-16-17 Peat-Lite
Similar to 20-20-20 but with over 60% nitrate nitrogen, boosted
micronutrient levels. Much less acidic reaction in the root media.
Balanced N-P-K ratio is excellent for producing fast-growing plants or
for maintaining plants in a sales environment. Geared for all plants,
especially our friend, the geranium. Great choice when trying to maintain
finished plants in a garden center. NO3: 9.25%; NH4: 3.15%; Urea:
2.6%; EC per 100 ppm N: 0.68 mS/cm; 100 ppm N @ 1:100: 9 oz/gal
conc.; 1 level tsp/gal = 188 ppm N; CCE = 122/lb CaCO3
15-0-15 Dark Weather Peat-Lite
Jack’s Dark Weather Peat-Lite is an ideal product for growers who
want a non-phosphorus, high nitrate product with calcium. The macro
nutrient and secondary nutrient levels are very similar to the standard
Dark Weather. Elevated to provide a boost of micros when growing
in a soilless or “peat-lite” mix. Alternate with 20-10-20 Peat-Lite or use
as a “finisher” for flowering plants like poinsettias. Has the Peat-lite
micronutrient levels needed for commercially made peat-lite potting
media. May be used on all plants. NO3: 12.12%; NH4: 0.58%; Urea:
2.3%; EC per 100 ppm N: 0.74 mS/cm; 100 ppm N @ 1:100: 9 oz/gal
