CO2 Box – Natural Contribution of Carbon Dioxide for Indoor Crops
Do you want to take your crop to the next level in growth and flowering? The CO2 Box is the natural and efficient solution for significantly increase the concentration of carbon dioxide (CO₂) in your grow cabinet, promoting more efficient photosynthesis and accelerating the development of your plants.
Thanks to its 100% organic formula, this system releases Additional CO₂ for 3 weeks, reaching concentrations of up to 1,500 ppm, well above the average environmental level of 300 ppm. It is ideal for spaces up to 1.20 x 1.20 x 1.20 meters, whether you place the box on the floor or prefer to hang it.
Why use CO₂ in cultivation?
Carbon dioxide is an essential gas for photosynthesis. Increase your concentration:
-
Improves photosynthetic efficiency, accelerating the plant's metabolism.
-
Promotes the production of flowers and fruits more voluminous and with better quality.
-
Strengthens cellular structure and general vegetative development.
Simple and fast way of use
-
Open the box and take out the bag.
-
Unscrew the white cap and remove the blue seal.
-
Fill with 1 liter of tap water.
-
Close with the white lid and shake for 30 seconds.
-
Place the bag back into the box, pierce the die and position the lid in the opening.
-
Replace the white cover with the red cap and close the box.
-
Place it on the ground or hang it in the growing space.

How to use
1. Open the container and add 1 liter of tap water.
2. Close tightly and shake for 30 seconds to allow the contents to fully hydrate.
3. Pierce the marked die-cut hole in the container: this is where the CO2 will come out.
4. Place the box above the grow area, as CO2 is heavier than air and tends to sink.
5. Let it work for about 3 weeks; after that, the CO2 will run out and need to be replaced.
6. Ventilate the grow tent before putting your head inside, especially if it has been closed for several hours.

Frequently asked questions
-
It's activated in one minute: you add 1 liter of tap water, shake for 30 seconds and pierce the die-cut. From then on, it starts releasing CO2 without you needing to do anything else. It doesn't need a controller or solenoid valve: it's plug and play.
-
It maintains between 1,200 and 1,500 ppm for 3 weeks. The recommended space is up to 1.2 × 1.2 × 1.2 m. It's a performance level designed just for small cabinets.
-
No. It's a 100% natural generator, no electricity, no flame and no controller needed. It also doesn't generate heat, so it doesn't disrupt the thermal balance of your cabinet.
-
In a closed cabinet the concentration rises, so ventilate before putting your head inside. Normal air is around 420 ppm, and above roughly 5,000 ppm there's a real health risk. Don't leave the cabinet closed without extraction in a small room where someone sleeps.
-
Below 2 m³ it's exactly its territory and anything else would be overspending. Between 2 and 10 m³, a larger-format consumable or a disposable bottle is more suitable. From 10 to 30 m³, a controller with an NDIR sensor already pays off, and above 30 m³, propane combustion with controlled climate.
-
The product is sold dry: you add the water when activating it. Some distribution sheets state 3.74 kg, which would correspond to the already hydrated product. The shipping weight we apply is that of the dry package.
