Cutting Edge Solutions Sour-Dee 0-0-2

Sour-Dee provides potassium, along with a carbohydrate and electrolyte source. Sour-Dee proprietary formula contains polysaccharides folded into a mineral matrix. This formulation acts as a compensator during lowered, end-of-season sunlight levels. Lowering light levels can cause a drop in photosynthetic rate and ATP (plant-sugar) production, essentially starving the plant of necessary energy. The additional carbohydrates in Sour-Dee fuel the metabolic processes required to drive fruit growth, flower growth, and produce heavy yields. Sour-Dee was formulated for plants with more of a sweet (berry/fruity) fragrance. Sour-Dee assists the plant in building upon its natural terpene footprint. Sour-Dee is a must use, in any aromatic plant feeding schedule.

Primary Benefits:

  • Improved fragrance
  • Stronger fragrance
  • Higher sugar content in fruits and flowers
  • Environmental stress relief and resistance
  • Significant increase in resin production


Directions for Use:

This is a highly concentrated solution. Never mix undiluted concentrates, as this may result in nutrient lock-up. Add each nutrient consecutively, allowing ample time for each concentrate used to thoroughly dilute and mix into the water. If preparing a nutrient stock tank, to be used over a period of time exceeding 24 hours, you must aerate nutrient reservoir regularly.

Shake well and measure carefully using a milliliter measuring cup. If using Micro 6-0-0™, add Micro 6-0-0™ first to water, then other nutrients.

After nutrients are mixed in water, adjust pH to 4.5-6.5. If your pH naturally falls within these parameters, pH adjustment is not necessary.

Monitor ppm and EC in reservoir and top off with fresh water as needed.

Reservoir temperature should be 60-68 degrees F.
