CO2 Pad Kit with Hanger
The simplest and cheapest CO2 delivery system available: a pad that absorbs moisture from the air and releases CO2. No electricity, no flame, no tanks, and no controller. The kit includes a hanger for suspending it over the crop.
How it works
The pad reacts with moisture in the air. To keep it active, spray about 50 ml of water once a day, first thing in the morning. From there, it gradually releases CO2 throughout the day.
Specifications
- Coverage: up to 5 m³
- Duration: 2-3 weeks
- Activation: ~50 ml of water sprayed once a day
- Does not expire in its packaging while sealed
- Can be cut into pieces for propagators or small spaces
- Includes hanger for suspending over the crop
- No electricity, no heat, and no flame
Does not expire and can be cut
Two practical features that set it apart from other consumables: as long as the packaging remains sealed, it does not expire, so you can keep spares without worry; and it can be cut into pieces, allowing you to distribute it among several propagators or adjust the CO2 supply for a very small space without waste.
⚠️ Safety: CO2 is not harmless
High concentrations of CO2 are dangerous to people. Normal air contains around 420 ppm, and above about 5,000 ppm, there is a real health risk. Although this is the gentlest CO2 delivery system in our catalog, the general rule remains the same: never enter a room with active dosing without ventilating it first. In a closed cabinet inside a small room, ventilate before working inside.
Is it what you need?
- Less than 2 m³: yes, it is exactly what it is designed for. Anything else is over-investment.
- 2-10 m³: it covers up to 5 m³; for anything larger, a larger consumable or a disposable tank is better.
- 10-30 m³: at this size, a controller with an NDIR sensor is more cost-effective.
- More than 30 m³ with controlled climate: propane combustion.
Replacement
When it runs out, there is no need to replace the entire kit: the replacement (ref. 681011) is just the pad, allowing you to reuse the hanger you already have.

How to use
1. Remove the pad from its packaging only when you are ready to use it: it does not expire while sealed.
2. Hang it using the included hanger above the level of the plants.
3. Spray about 50 ml of water onto the pad first thing in the morning.
4. Repeat the spraying once a day to maintain CO2 release.
5. If your space is very small or you use propagators, cut the pad into pieces and distribute them.
6. Replace the pad after 2–3 weeks with the refill, ref. 681011, and ventilate the area before working inside.

Frequently asked questions
-
It is a pad that absorbs moisture from the air and releases CO2 gradually. It needs no electricity, no flame, no cylinders and no controller. It is the simplest and cheapest way of supplying CO2 there is.
-
You spray it with around 50 ml of water once a day, first thing in the morning. From then on it releases CO2 gradually throughout the day. That is all the maintenance it needs.
-
It covers up to 5 m³ and lasts 2 to 3 weeks. The kit includes the hanger so you can hang it right above the plants. It produces no heat and no flame, so it does not affect the climate inside the tent.
-
It does not expire as long as the packaging stays sealed, so you can keep one in reserve without any rush. It can also be cut into pieces, which lets you share it between several propagators or match the supply to a very small space without waste. Those are two details that set it apart from the other consumables.
-
There is no need to buy the complete kit again: the refill (ref. 681011) is just the pad and reuses the hanger you already have. It works out cheaper and you create less waste. It is the usual purchase from the second cycle onwards.
-
Below 2 m³ is exactly its territory and anything else would be over-investing. Between 2 and 10 m³ it covers up to 5 m³; above that a larger consumable or a disposable cylinder is better. From 10 to 30 m³ a controller with an NDIR sensor pays off, and above 30 m³ with climate control, propane combustion.
