Cutting Edge Sour-Dee SP™ 0-0-24 Bloom Supplement — 5lb

0-0-24 Potassium-Sulfur Bloom Powder for Citrus Profiles, 5lb

Two crops fed the exact same base nutrient program can still finish with very different aromatic character, and a chunk of that difference traces back to potassium and sulfur availability during the bloom phase. Sour-Dee SP 0-0-24 delivers 24% soluble potash and 8.5% sulfur alongside a micronized carbohydrate source, calibrated to guide flowering crops toward citrus, tropical, and fuel-forward aromatic expressions.

This 5lb soluble powder dissolves into fertigation solutions or a soil drench, feeding both the crop and the beneficial microbes in the root zone throughout the bloom cycle.

Key Features & Benefits

• 24% soluble potash (K₂O) — high-potassium loading drives carbohydrate translocation to developing flowers during peak bloom demand.
• 8.5% sulfur — supports biosynthesis of the sulfur-containing aromatic compounds and essential oils tied to flavor development.
• 24% micronized carbohydrate source — finely milled sucrose from evaporated cane juice and molasses feeds beneficial root zone bacteria and fungi.
• Guides citrus, tropical, and fuel-forward aromatic expression — targeted K-S nutrition during flowering supports development of these aromatic profiles in predisposed cultivars.
• Universal system compatibility — integrates with hydroponic, living soil, amended coco, and recirculating nutrient programs.

Who Should Use This

Boutique and commercial growers targeting citrus, tropical, and fuel-forward flavor and aroma profiles use Sour-Dee SP as a bloom-phase potassium supplement that also feeds root zone microbial activity, particularly in living soil and amended coco systems where biology and potassium availability both shape final product quality. Sugaree SP is the companion option for growers chasing a different aromatic direction from the same 0-0-24 formula.

Frequently Asked Questions

What is the difference between Sour-Dee SP and Sugaree SP?

Both are 0-0-24 potassium-sulfur powders with micronized carbohydrates, but they are calibrated to guide different aromatic expressions. Sour-Dee SP targets citrus, tropical, and fuel-forward profiles, while Sugaree SP targets a different aromatic direction, so the choice comes down to your cultivar and desired flavor outcome.

How does the carbohydrate component affect reservoir cleanliness?

At recommended rates, the micronized carbohydrate content is minor and unlikely to cause significant algae or biofilm buildup in a well-maintained recirculating system. Keep reservoirs lightproofed and follow standard cleaning practices to further minimize any risk.

When should I start using Sour-Dee SP?

Begin incorporating Sour-Dee SP at the onset of the flowering phase, when potassium demand rises and the crop shifts from vegetative to reproductive growth. Continue through late bloom and into pre-harvest for sustained flavor development.

Can this be used in hydroponic systems without living soil microbes?

Yes, the potassium and sulfur nutritional benefits apply in purely hydroponic systems regardless of microbial activity present. The carbohydrate component simply will not deliver its root-zone-biology benefit as fully as it does in living soil or amended media.
