For high-value crops, this product is best used for pre-plant inoculation or fertigation/soil drench. The following are maximum one-time application rates. If budget-constrained, I suggest cutting the application rates and applying more frequently throughout the season.

Fertigation/Soil Drench

  1. Mix 1 tsp. to 1 Tbsp per gallon of water.

  2. Apply every 7-10 days through drip irrigation or apply 8 oz. per plant around the root zone for 6” pots, 32 oz. per 5 gallon pot, 64 oz. per 10 gallon pot, etc.

Pre-Plant Propagation Inoculation and Starter Program

  1. Mix 1 tsp. to 1 Tbsp in 10 gallons of water to soak plugs or soil prior to propagation.

  2. Lightly mist new seedlings with a mixture of 1 oz. Spectrum per gallon of water in conjunction with trace minerals.

  3. Repeat weekly after plants are 12-15” high and have at least three full sets of leaves.
