Elevate your standard CVG mix into a premium, manure-equivalent substrate with this “Low-Tek” booster kit. No sterilization needed!
Transform your CVG: Premium results, zero manure hassle.
Unlock the secret to premium mushroom yields without the mess and complexity of traditional manure substrates. The Low-Tek CVG Booster Kit is engineered to transform your standard Coco, Vermiculite, and Gypsum (CVG) mix into a nutrient-rich, contaminant-resistant powerhouse, comparable to the finest supplemented manure.
This kit is your shortcut to achieving “manure-equivalent” results using a simple, “low-tek” preparation method. Instead of a barren, nutrient-poor CVG base, you’ll create a substrate that actively supports robust fungal growth, leading to massive flushes. The secret lies in the precisely formulated BioaKt and BAC amendments. BioaKt aids pasteurization and accelerates colonization, while BAC, featuring Biological Active Carbon, establishes a microbial shield, significantly boosting contamination resistance with mineralized proteins.
Here’s how it works:
Simply combine your own:
- 1 kg of coco coir
- 5 liters of vermiculite (approximate 600gram)
- and 80g Gypsum (Optional for traditional CVG)
with the BioaKt and VermiChar BAC! from this kit.
Hydrate with 6 liters of boiling water in 20L bucket or cooler box.
NOTE: will expand to 17-18 liters – dependent on your Coco coir.
The Bundu-Tek Method ensures pasteurization through heat and pH, eliminating the need for pressure cooking or complex sterilization. Once cooled, your enriched substrate is ready to be inoculated.
This kit provides the perfect boost for approximately 15-20 liters of finished substrate, making it ideal for growers seeking high performance without the fuss. Stop compromising your genetics with basic CVG. Elevate your cultivation with the Low-Tek CVG Booster and experience premium results with unparalleled ease.
Grow-in-Bag BE
Case Study: The Super-CVG “Manure” Test – Quadrupling Yields (April 2026)
Case Study: The Super-CVG “Manure” Test – Quadrupling Yields (April 2026)
For this test, we targeted a prime horse manure equivalent, aiming for a 3% protein profile, by use of BAC supplementation. The base was our Bundu Boom CV (Coco/Vermiculite), prepared in a 10x8x50cm “Grow-in-Bag” at 80% moisture content via the Bundu-Tek method.
Substrate Dry Mass: 130g
Total Fresh Harvest: 510g (across 2 flushes)
Biological Efficiency (BE): 392.3%

The Verdict: Most commercial growers aim for 100% BE wit CVG, with 30-50% spawning rate. By aiming for a protein profile of pure aged pasture manure with precision additives, we quadrupled the BE fresh mushrooms using a purely synthetic, clean-handling mix and normal 5% spawning rate. This completely bypasses intense sterilization cycles tied to supplemented subtrates, with simple Pasteurization Bundu Tek.
Preperation
Bundu-Tek Method:
1. The Dump: Add your 1 kg coco coir and 5 Liters of vermiculite (600gram) in 20-Litre Bucket – or cooler box – break up the coco coir. Empty both kit ingredients (100ml tub BioaKt) and the Engine Bag ( about 500ml BAC) and dry mix to get to a homogenous consistency.
2. The Scald: Pour in 6000ml (6kg) of boiling water. Close the lid tightly to lock in the thermal mass.
3. The Pasteurize: Let sit for 12-16 hours. The substrate must be below 30°C before inoculation.
4. The Inoculate: Sanitize hands with rubbing alcohol. Mix thoroughly with your mushroom spawn and bag/box in your growing container.
