Cutting Edge Solutions Sour-Dee, 6 gal

Potassium and Carbohydrate Supplement for Flowering, 6 Gal

Flowering crops draw heavily on carbohydrate reserves as they shift resources into flower and fruit development, and potassium plays a central role in moving those sugars to where the plant needs them most. Cutting Edge Solutions Sour-Dee pairs a 2.0% soluble potash (K2O) base with a finely micronized carbohydrate source built specifically for the flowering window, giving growers a way to support sugar transport and flower development without adding nitrogen or phosphorus late in the cycle.

The 6 gal size fits a regular indoor grow adding Sour-Dee to a flowering-phase feeding schedule.

Key Features & Benefits

• 0-0-2 potassium base — delivers 2.0% soluble potash (K2O) with no added nitrogen or phosphorus, keeping late-cycle macronutrient additions targeted.
• Micronized carbohydrate source — a finely processed 2% sucrose component, derived from evaporated cane juice and molasses, supplies carbohydrate energy tailored to the flowering phase.
• Formulated for flowering — built specifically for the flowering window rather than as a general-purpose additive used across the full cycle.
• Feeds beneficial soil microbes — the carbohydrate component also serves as a food source for beneficial microorganisms in soil and living-soil systems.
• Compatible with CES and outside programs — layers onto the CES base and additive lineup or an outside fertilizer program without reformulating either.

Who Should Use CES Sour-Dee

Growers running a flowering crop who want a dedicated potassium and carbohydrate supplement for the bloom phase, including living-soil growers who want the added carbohydrate to support the microbial population in the root zone.

About Cutting Edge Solutions

Cutting Edge Solutions traces back to 2001, when founder John Piccirilli, known around the industry as “Uncle John,” turned decades of hands-on cultivation experience into a commercial nutrient line. Sour-Dee sits in the company's Advanced Molecular family alongside Sugaree and Bulletproof Si, additives built to layer onto the Micro/Grow/Bloom base rather than replace it. CES nutrients are formulated, bottled, and shipped from the company's own facility in White City, Oregon.

Frequently Asked Questions

What is Cutting Edge Solutions Sour-Dee?

Sour-Dee is a 0-0-2 potassium supplement built around a finely micronized carbohydrate source, formulated specifically for the flowering phase. It delivers 2.0% soluble potash along with a 2% sucrose component derived from evaporated cane juice and molasses, with no added nitrogen or phosphorus.

How does Sour-Dee support flowering plants?

During flowering the plant channels a large share of its energy into sugar transport and flower development, and Sour-Dee's potassium content helps move those sugars through the plant's vascular tissue. The micronized carbohydrate component supplements the plant's internal sugar supply during that same demand window.

How is Sour-Dee different from CES Sugaree?

Both products are Advanced Molecular family additives used during flowering, but Sour-Dee is built around a 0-0-2 potassium and micronized-sucrose formula, while Sugaree is a polysaccharide and trace-mineral carbohydrate matrix. Growers can use either on its own or run both as part of a fuller flowering additive stack, per the CES usage guide.

When should I start using Sour-Dee?

Sour-Dee is designed for the flowering phase, so introduce it once the plant transitions from vegetative growth into bloom. Follow the CES usage guide for the specific dosing schedule across the flowering window.

Can Sour-Dee be used in living soil?

Yes, the micronized carbohydrate component in Sour-Dee provides a food source for beneficial microorganisms, which makes it a reasonable fit for living-soil and organic-leaning programs in addition to standard hydroponic reservoirs. Dosing still follows the flowering-phase schedule in the CES usage guide.
