Uncle Myc's CVG Supplemented Bulk Substrate - 8 lb

Sterilized Coco Coir Blend for a Clean Start - 8 lb

Contamination can undo weeks of work before a culture establishes. This supplemented bulk substrate combines coco coir, vermiculite and gypsum and is sterilized in certified autoclaves, so you begin with a medium that has already been through a sterilizing step rather than only pasteurization.

The 8 lb unit suits hobbyists running a first trial and regular indoor growers who want to fill several containers or test a method before buying in larger volume.

Key Features & Benefits

• Sterilized in certified autoclaves — removes a preparation step and supports a cleaner start.
• Coco coir, vermiculite and gypsum blend — a combination of fibre, moisture-holding mineral and mineral supplement in one medium.

Who Should Use Uncle Myc's CVG Supplemented Bulk Substrate

Home gardeners and licensed growers who run controlled indoor specialty cultivation and want a ready-sterilized medium will find it useful. It suits anyone replacing in-house sterilizing with a purchased, pre-treated blend.

Frequently Asked Questions

Q: What is in this substrate?
A: It is made from coco coir, vermiculite and gypsum. Coir provides fibre, vermiculite helps hold moisture, and gypsum is a mineral supplement.

Q: What does autoclave sterilization mean?
A: An autoclave uses pressurized steam to treat material at high temperature. It is a more thorough step than pasteurization, which uses lower heat.

Q: Which species can I use it with?
A: It is listed as compatible with all gourmet and medicinal species. Check your own culture's needs before committing a large batch.

Q: Is it sold as a multi-pack?
A: No. It is sold as a single 8 lb unit.

Q: How should I handle it to keep it clean?
A: Work on a sanitized surface, wash your hands, and use clean containers and tools. Keep the bag closed until you are ready to use it.
