The Enhancer — TNB CO2 Natural CO2 Generator for Grow Tents & Small Spaces
Best for: Growers wanting to boost CO2 levels without tanks, regulators, or heat-producing burners
Our thoughts
This is a proper quick-hit CO2 solution for growers who want to test enrichment or need a rapid boost without the capital spend of a burner setup. Add water, shake, walk away. No propane faffing, no regulator headaches, no extra heat in the tent. Does exactly what it should.
The Enhancer is a natural CO2 generator canister designed to deliver fast, steady CO2 enrichment to indoor grow spaces without any additional equipment. Made from 100% organic all-natural ingredients, each 240g canister activates with just warm water and produces CO2 for up to two weeks. It's one of the most straightforward ways to reach CO2 levels of 900–1200 ppm in smaller to mid-sized grow tents, and it eliminates the need for dangerous propane burners, regulators, or complex monitoring systems.
How it compares
The Enhancer sits in the natural CO2 segment, competing against CO2 bags and burner systems.
-
vs. CO2 bags (Exhale): Activates instantly (8–10 hours) instead of 30–45 days; requires maintenance shaking; shorter lifespan (2 weeks vs. 6 months); lower cost per activation
-
vs. CO2 burners: No heat output; no regulator needed; safer; lower upfront cost; produces less CO2 for larger spaces
-
vs. CO2 tanks: Portable; no heavy equipment; no ongoing tank refills; designed for spaces up to 12×12×12
In short: fastest activation, simplest operation, ideal for growers who don't want complexity or heat.
Usage guidance
Activation
Remove the cap, add one litre of warm water, replace the cap, cover the small hole with your thumb, and shake vigorously. CO2 release begins within 8–10 hours.
Maintenance
Shake once daily for spaces up to 12×12×12, or every other day for smaller 6×6×6 areas. This keeps CO2 flowing steadily throughout the two-week cycle.
Ideal space size
Each canister reaches 900–1200 ppm in a 12×12×12 grow space (1,728 cubic feet). In smaller tents, performance extends longer and peaks higher.
Refilling
Once a canister is spent, replace it or use TNB refill packs to continue enrichment. Two weeks per canister means recurring costs, but no equipment investment.

Who this is for
- Growers testing CO2 enrichment before investing in burners or tanks
- Small tent and cabinet growers where space and heat are limiting factors
- Budget-conscious growers who want CO2 results without major capital outlay
- Experienced growers looking for a backup or secondary CO2 source
- Anyone who wants simplicity over a long-term passive system
Particularly suited to UK tent growers where ventilation is already tight and extra heat is unwelcome.
Our take
The Enhancer is a no-fuss CO2 boost that actually works. You're getting proper CO2 enrichment without propane safety concerns, heat stress, or regulator complications. The catch is it only lasts two weeks and needs a daily shake, but if you're serious about testing CO2 or running a smaller space, that's a fair trade-off.
Worth picking up if you want to see what CO2 enrichment does for your plants without betting the farm on expensive equipment. Good time to buy while stock lasts.
