TNB Naturals The Enhancer – Yeast-based CO2 generator, ~1,200 ppm for 2 weeks

TNB Naturals The Enhancer

240 g yeast fermentation bottle that continuously generates CO2 without electricity, without a flame, and without producing heat. It is activated with 1 liter of warm water and starts working. Plug and play: it does not require a controller or solenoid valve.

Performance

• Concentration: ~1,200 ppm in a space of 3.6 × 3.6 × 3.6 m
• Continuous supply for 2 weeks, after which it declines
• Contents: 240 g
• Activation: 1 L of warm water
• Does not produce heat
• Recyclable bottle and biodegradable contents

Use and maintenance

Add 1 liter of warm water, close it, and place it above the crop (CO2 is heavier than air and sinks). Shake the bottle every 2 days to reactivate the fermentation and maintain a stable supply. After about two weeks, production clearly declines: that is the time to refill it.

It does not heat up, and that matters

A propane generator adds both heat and power to the room, which in a small space forces you to increase extraction—and extraction expels the CO2. A fermentation generator does not add heat, so it does not alter the thermal balance of your cabinet.

⚠️ Safety: CO2 is not harmless

CO2 at high concentrations is dangerous for people. Normal air is around 420 ppm; with this bottle, the goal is ~1,200 ppm, and above about 5,000 ppm there is a real health risk. Never enter a room with active dosing without ventilating first: open it, ventilate for a few minutes, and enter afterward. Do not use it in a closed cabinet inside a small room without extraction, and especially not where someone sleeps.

Refill

When it runs out, there is no need to buy the whole bottle: there is the Enhancer Refill Pack (ref. 672207). Empty the bottle, rinse it, and refill it with the refill pack. It is much cheaper and generates less waste.

Is it what you need?

• Less than 2 m³: yes, it is exactly what it is designed for, along with the CO2 Box and the CO2 Pad.
• 2-10 m³: it also fits, or a larger format consumable.
• 10-30 m³: here a controller with an NDIR sensor is already worth it.
• More than 30 m³ with controlled climate: propane combustion.

At GrowIndustry we only work with proven quality products and trusted brands.

Every item goes through a check before shipping to make sure it arrives in perfect condition and ready to use.

Your satisfaction is our priority.

1. Open the jar and add 1 liter of lukewarm water (neither cold nor boiling, so as not to damage the yeast).
2. Close tightly and shake to mix the contents completely.
3. Place it above the level of the grow: CO2 is heavier than air and tends to sink.
4. Shake the jar every 2 days to reactivate fermentation and maintain a stable supply.
5. After 2 weeks, production clearly declines: it is time to use the Refill Pack (ref. 672207).
6. Ventilate the cabinet or room before putting your head inside.
