• Top Dress at 1/4 - 1 Cup Per Plant.

Craft Blend isn’t a random mix of organic inputs. It’s a deliberately balanced amendment designed to feed the soil biology first, so the plant can take what it needs when it needs it. Below is a breakdown of the core ingredients and what they actually do in a living soil system.

Thorvin Premium Kelp Meal

A cold-processed kelp meal rich in natural growth hormones and trace minerals. Kelp supports root development, stress resistance, and overall plant vitality without forcing growth. It’s a foundational biological stimulant, not a fertilizer shortcut.

Black Soldier Fly Insect Frass

Insect frass feeds soil microbes and adds gentle nutrition with extremely low heavy metal content. Think of it as a biological catalyst, it helps wake up the soil food web and supports healthier nutrient cycling.

Alfalfa Meal

A natural nitrogen source with growth-promoting compounds that encourage vigorous vegetative development. Alfalfa also improves soil structure, making it easier for roots to explore and access nutrients.

Organic High-P Bran

A phosphorus-rich input that supports root development and flowering. This ingredient plays a key role later in the cycle, helping plants transition into bloom without sharp nutrient swings.

Camelina Meal

A unique omega-rich seed meal that supports soil fertility and plant resilience. Camelina helps strengthen a plant’s natural defense systems while contributing to long-term soil health.

Crustacean Meal

High in chitin, crustacean meal supports stronger cell walls and improved pest resistance. It also contributes calcium and helps improve soil structure, aiding water retention and nutrient uptake.

Fish Meal

A clean, organic source of nitrogen and micronutrients. Fish meal provides steady nutritional support without the harsh spikes associated with synthetic inputs.

Fish Bone Meal (Triple Strength)

A slow-release source of calcium and phosphorus from wild-caught fish. This ingredient supports structural strength, root development, and sustained flowering over time.

Organic, Non-GMO Food-Grade Soybean Meal

A plant-based nitrogen source with a complete amino acid profile. Soybean meal supports vegetative growth and soil biology without relying on animal byproducts.

Sul-Po-Mag (Langbeinite / K-Mag)

A naturally occurring mineral that delivers potassium, magnesium, and sulfur. These elements are critical for photosynthesis, stem strength, and terpene development.

Organic Malted Barley

A powerful enzyme source that helps unlock nutrients already present in the soil. Malted barley accelerates biological activity and improves nutrient availability without adding excess salts.

Volcanic Tuff & Micronized Basalt

These volcanic minerals supply a broad spectrum of trace elements that support root strength, microbial diversity, and long-term soil vitality.

Gypsum & Oyster Flour

These calcium-rich amendments improve soil structure, prevent nutrient lockout, and support strong cell walls. Calcium availability is critical in container systems, and these inputs provide it in a gentle, plant-available form.

Ingredients We Avoid (On Purpose)

At Green Zone, we care just as much about what’s not in a product as what is. Many so-called “organic” amendments are technically approved for organic use but sourced from places we don’t believe belong in living soil.

Craft Blend intentionally avoids:

• Steamed Bone Meal – Byproducts from industrial slaughterhouses
• Blood Meal – Same sourcing concerns as bone meal
• Chicken Manure – Rarely sourced from truly organic-fed birds
• Feather Meal – Another manure-derived byproduct
• Biosolids – Treated municipal human waste sold as fertilizer

Even when labeled “organic,” these inputs often come with sourcing and contamination concerns that don’t align with long-term soil health.

The Green Zone Takeaway

Craft Blend works because it respects the soil food web instead of trying to overpower it. When paired with proper container size and consistent moisture, it becomes a low-stress way to maintain a living soil system over time.
