CO2 Diffuser
Boost CO2BOX 409 g: the growth lever most indoor growers overlook
Inside a sealed tent, CO2 drops below 400 ppm within hours and photosynthesis slows right down, whatever your lighting. The CO2BOX Boost fixes that bottleneck with a single litre of tap water.
A self-running biological reaction, no pressurised gas
The bag holds 409 g of dry organic substrate. Add one litre of water and the reaction releases CO2 steadily for roughly twenty days, no spikes and no sudden drops. No regulator, no valve, no sensor.

1500ppm CO2
20days run time
1.44m² covered
🌱 Photosynthesis unlocked
Three to four times ambient levels: denser foliage, tighter internodes and a visibly sturdier plant structure.
⏱️ Ready in two minutes
Pour in a litre of water, stir, then hang it above the canopy — CO2 is heavier than air and settles onto the leaves.
🛡️ Completely safe
Organic substrate, nothing under pressure, no leak risk. Store it and move it without special handling.
When in the cycle should I use the CO2BOX?
During vegetative growth and the first two to three weeks of flowering, when metabolism peaks. On seedlings or freshly rooted cuttings it is simply too early.
Do I need to adjust my tent temperature?
Yes. For that extra carbon to become biomass, aim for 25 to 30 °C with sufficient light intensity. Below that range the benefit stays marginal.
Lighting and nutrition already sorted? CO2 is usually the last missing link.
