Full description
CO2 Pad Refill
Replacement pad for the CO2 Pad Kit with hanger (ref. 681009). Reuse the hanger you already have and replace only the consumable: it absorbs moisture from the air and releases CO2, with no electricity, flame, or controller.
How to use
Hang it over the crop and spray about 50 ml of water once a day, first thing in the morning. From then on, it releases CO2 gradually 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 as long as it remains sealed
- Can be cut into pieces for propagators
- No electricity, no heat, and no flame
The advantage of it not expiring
As long as the packaging is sealed, the pad does not expire, so you can buy several and keep them in storage without them spoiling. It is the only CO2 consumable in the catalog for which this can be said.
⚠️ Safety: CO2 is not harmless
CO2 at high concentrations is dangerous to people. Normal air is around 420 ppm, and above about 5,000 ppm there is a real health risk. Although this is the mildest CO2 source in the catalog, the rule does not change: never enter a room with active dosing without ventilating first.

Frequently asked questions
-
It is the replacement pad for the CO2 Pad Kit with hanger (ref. 681009). You only replace the consumable and reuse the hanger you already have. It works the same way: it absorbs moisture from the air and releases CO2, with no electricity, no flame and no controller.
-
No, this item is the pad only. If this is your first purchase, start with the kit including the hanger (ref. 681009) and buy only refills from then on. That way it works out cheaper and you create less waste.
-
You hang it above the plants and 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. It needs nothing else.
-
It covers up to 5 m³ and lasts 2 to 3 weeks. It can also be cut into pieces to share it between propagators or adapt it to very small spaces. It produces no electricity, no heat and no flame.
-
Yes. As long as the packaging stays sealed the pad does not expire, so you can keep several in storage without them going off. It is the only CO2 consumable in our catalogue you can say that about.
-
Even though this is the gentlest supply in our catalogue, the rule does not change: never go into a room with dosing active without ventilating first. Normal air is around 420 ppm and above roughly 5,000 ppm there is a real health risk. Ventilate for a few minutes and then go in.
