Description
Three weeks of added CO2 for a tent, with no cylinder, burner or wiring
The Easy Grow CO2 Box is a self-contained CO2 release pack for grow tents and small grow spaces. Add 1 litre of tap water to the bag inside, shake, set it back in the box and it releases carbon dioxide steadily for around three weeks. Easy Grow rate one box for a space up to 1.2 x 1.2 x 1.2 m and recommend it through both the vegetative and flowering stages. It stands on the floor or hangs from the tent frame by its built-in hanger.
Key Benefits
- No equipment – no gas bottle, regulator, controller or power needed
- Around three weeks of release from one activation
- Sized for tents up to 1.2 x 1.2 x 1.2 m
- Set up in minutes – water, shake, close the box
- Hang it or stand it – a built-in hanger on top of the box
Is CO2 holding back your growth rate?
Outdoor air carries roughly 400 ppm of CO2, and fast-growing plants in a closed tent can use much of that within an hour, so photosynthesis slows even when light, feed and temperature are right. Topping the air up gives the leaves more carbon to work with during the light period, supporting stronger vegetative growth and flowering – the gains are greatest in a sealed or slow-extraction tent, where the CO2 is not pulled straight out again.
How to Use
- Open the box and take out the bag; unscrew the white lid and remove the blue security seal
- Add 1 litre of tap water, refit the white lid and shake for 30 seconds
- Put the bag back in the box, push out the perforated hole and seat the white lid in the opening
- Swap the white lid for the red lid and close the box
- Hang it in the tent or stand it on the floor – CO2 is heavier than air, so hanging it above the canopy spreads it best
- Replace it after about three weeks

Frequently Asked Questions
How long does one box last?
Around three weeks once activated. Start a fresh box when it is spent to keep the CO2 topped up.
Should I turn my extraction off?
No – keep your temperature and humidity in check. CO2 works best where air changes are slow, so run extraction on a speed controller or thermostat rather than flat out, and keep the tent closed.
How is it different from an Exhale bag?
An Exhale bag grows CO2 from a living mushroom culture over several months. The CO2 Box is a water-activated pack that releases over about three weeks – a short, simple top-up.
