Not So Simple Substrate – Advanced Nutrient-Enriched Blend

Enhanced Nutrition. Serious Performance.
The Not So Simple Substrate is designed for growers who want more than a basic CVG blend. This advanced formula combines coco coir, vermiculite, gypsum, worm castings, Azomite, and erythritol to create a mineral-rich, biologically supportive environment for aggressive colonization and strong flush potential.

What Makes It Different?

  • Worm Castings – Adds natural biological complexity
  • Azomite – Over 70 trace minerals for balanced growth support
  • Erythritol – Supplemental carbohydrate component
  • Optimized CVG Base – Proven hydration and structure
  • Hydrated to Field Capacity – Ready to mix immediately

Prepared for Clean Handling

  • Prepared in Unicorn XLS-A filter patch bags
  • Double vacuum-sealed for added sterility protection
  • Shelf life up to 2 months when stored properly
  • Compatible with monotubs or in-bag fruiting (Baglife-style workflows)

Available Sizes

  • 3lb
  • 5lb
  • 10lb (2 × 5lb bags)
  • 20lb (4 × 5lb bags)

Quick Start Guide

Step How to Use
1. Inspect Confirm seals and filter patch are intact.
2. Mix with Grain Spawn Combine fully colonized grain at a 1:1 to 1:3 ratio in a clean container or bag.
3. Incubate Store at 70–75°F until fully colonized (typically 7–14 days).
4. Initiate Fruiting Introduce fresh air, indirect light, and proper humidity.
5. Harvest Harvest mature fruits. Additional flushes may be possible with proper care.

Storage Guidelines

  • Store sealed between 45°F and 70°F
  • Avoid freezing or excessive heat
  • Best used within 30–60 days of receipt

B.P.

the grain: i picked milo took off nicely, 2 cc’s per bag, 5 bags per syringe. Works very nice, bags will be done withing a week. I should break and shake right now but, I think ill wait another week or so. As for the bulk substrate, looks great ive been keeping it in our storage room, its super chilly in there. And, it should work great when the time comes. Personally, ive never had issues with any of the bags ive purchased. I hardly inoc in my SAB anymore, as theres no need I just flame sterilize the needle, and inoculate.
