Growbro CO2 Bottle – 1.8 kg of pure CO2 in a disposable and recyclable cylinder

Growbro CO2 Bottle

Cylinder with 1.8 kg of pure CO2. It is compressed CO2: immediate, clean supply and, above all, without adding a single degree of heat to the room. In medium-sized spaces, that is its great advantage over propane combustion.

⚠️ It is disposable: it is not refilled

It must be stated clearly before buying: this cylinder is disposable and recyclable. It is not refilled or recharged. When empty, it is recycled and a new one is purchased. It is not a refillable industrial bottle.

And a second honest clarification: we do not have refillable 6 or 10 kg bottles or a refill service. If your installation needs that format, you will have to look for it from an industrial gas supplier.

How long it lasts: manufacturer's consumption table

• 5 m³ room: 1.5 bottles per month
• 10 m³ room: 2.5 bottles per month
• 20 m³ room: 5 bottles per month

With those numbers you can calculate the real monthly cost before buying, which is what really decides if compressed CO2 pays off for you compared to other methods.

Specifications

• Content: 1.8 kg of pure CO2
• Disposable and recyclable cylinder
• Non-refillable
• Does not add heat or humidity to the room

You need the regulator

The bottle alone does not dispense. It needs the Growbro regulator (ref. 600559), which includes a solenoid valve and automatic switch. With it, and optionally with a CO2 controller with an NDIR sensor, you have a complete system.

⚠️ Safety: CO2 is not harmless

CO2 at high concentrations is dangerous for people. Normal air is around 420 ppm; an enriched room works at 1,200-1,500 ppm and above about 5,000 ppm there is a real health risk: headache, dizziness and, in extreme concentrations, loss of consciousness. Never enter a room with active dosing without ventilating first. Cut off the supply, extract for a few minutes and enter afterwards.

In addition, since it is pressurized gas: store the cylinder vertically, away from heat sources and direct sunlight, and do not puncture or incinerate it even if it appears empty.

Is it your step?

• Less than 2 m³: it is not worth it; a passive consumable covers it more than enough.
• 2-10 m³: here yes, as an alternative to a large consumable.
• 10-30 m³: its best ground, combined with an NDIR controller: it beats gas because it does not heat.
• More than 30 m³ with controlled climate: propane combustion is cheaper per kilo of CO2.

Note on weight

Some distribution sheets give 0 kg for this reference, which is an obvious catalog error. The weight we apply is an estimated shipping weight and realistic for the full cylinder.

At GrowIndustry we only work with proven quality products and trusted brands.

Every item goes through a check before shipping to make sure it arrives in perfect condition and ready to use.

Your satisfaction is our priority.

1. First, calculate your monthly consumption using the manufacturer's chart according to the volume of your room.
2. Place the cylinder upright on a stable base, away from heat sources and direct sunlight.
3. Mount the Growbro regulator (ref. 600559) on the bottle; no tools are required.
4. Connect the outlet to the diffusion line and position the emission point above the crop.
5. If you use a controller with an NDIR sensor, control the regulator's solenoid valve from it.
6. Cut off the supply and ventilate for a few minutes before entering the room. When the cylinder runs out, take it for recycling: do not puncture or incinerate it.
