The Growology® 3-Step System Our Growology® fertilizers are a result of our desire to offer you a superior product that's easy to use and that can produce excellent results when used properly. Drawing on over 80 years experience in plant nutrition, we've created water-soluble formulas that use the most sensible and agronomically viable combination of organic and non-organic ingredients to improve a grower's yield by bringing each plant to its healthy maximum. Every ingredient we use has been thoroughly tested and has a long history of proven results. Among these ingredients are mycorrhizae, an organic fungus that increases a plant's root mass and enhances its uptake of nutrients; magnesium for chlorophyll production and to facilitate photosynthesis; and both sulfated and chelated minor elements to provide your plants with the minerals they need to thrive. The Growology® family of products enables your plants to grow stronger and to be better able to resist pests and diseases.

Step 1 | for seedlings and new clones

50/50 Starter Mix

Analysis Details

Step 1 | Guaranteed analysis

  • Humates: 50%
  • Mycorrhizae: 50%

Growology® Step 1 is added to the soil in which new plants start their life. It's a blend of humates and a beneficial mycorrhiza, which is a fungus that grows around the young plant's roots to increase water and nutrient uptake throughout the plant's life cycle. Step 1 provides what a new plant needs to get off to a strong start.

Directions: Thoroughly mix 1 tablespoon with 1 gallon of soil or whatever growing medium you use. (That's 1/3 cup for a 5-gallon container.) That's all you do - the mycorrhizae and humates do the rest. (Don't use Step 1 for hydroponic growing.)

  • Soluble Potash (K2O) 10%
  • Magnesium (Mg) 3.0%
  • Boron (B) 0.02%
  • Copper (Cu) 0.05%
  • Iron (Fe) 0.10%
  • Manganese (Mn) 0.05%
  • Zinc (Zn) 0.05%

Step 2 is for a plant's vegetative stage. Its main ingredients are essential nitrogen, phosphate, potassium, and micronutrients in proportions that are ideally suited for all varieties to thrive, flourish, and grow.

Directions: Sprouts -­ early vegetation: use 1 tsp. per gal. per feeding. Full vegetation: 2 to 3 tsps per gal. per feeding. Growers’ conditions vary and they should adjust accordingly. Always increase dosage incrementally and never apply to dry soils.
