CO2 — Ventilation and Climate

CO₂ Tabs from No Mercy Supply are CO₂ tablets for quick and abundant flowering of your plants.

• 60 pcs. per pack
• add one CO₂ tablet to the water
• water your plant
• the plant will absorb CO₂ through its roots

Slowed plant growth is often caused by a lack of carbon dioxide, and in poorly ventilated rooms this deficiency can be decisive. With CO₂ tablets, you supply carbon dioxide directly to the roots of your plants, which significantly increases the rate of their growth.

Warning:

1. CO₂ tablets are active for around 4 - 6 hours in a given solution.
2. Adding CO₂ shortly before the dark period does not produce any results!
3. During the dark period, the plant does not absorb CO₂. 

Application:

• When your plants (or cuttings) are healthy, you can use 1 tablet per 100 l of water. Apply twice a week for optimal results and preferably throughout the entire cycle of growth of your plants. In hydro systems, you can simply add the tablet to the nutrient reservoir. Overdosing is neither harmful nor beneficial. If you want to add a CO₂  tablet immediately, first dissolve it in a glass of water (lightly crush the tablet in the water with your finger) and mix it into the water intended for the plants.

Made of durable, corrosion-resistant materials, this mini pressure regulator valve is designed to withstand high pressure and function reliably for many years. The control valve allows precise and easy flow adjustment, while the pressure gauge provides accurate measurement of system pressure.

The mini pressure regulator valve design makes it ideal for use with different types of CO2 cylinders. It connects easily and safely to ensure a continuous and stable CO2 supply.

Whether you are a professional grower or hobby gardener, the mini pressure regulator valve with pressure gauge for CO2 cylinders is a tool that provides control and confidence when supplying your plants with CO2. Its functionality and durability make it an indispensable accessory for every CO2 system.

CO₂ Boost is a natural CO₂ generator that provides your indoor garden with a continuous supply of CO₂ without heavy gas cylinders, heat, humidity or flames.

CO₂ Boost is an innovative system for natural CO₂ generation, consisting of a bucket containing a patented formula, a pump and a tube to deliver CO₂ to the growing area. The gardener only needs to connect it to their plants' light cycle and let the gas do its work. The direct result is an increased photosynthesis rate, ensuring much faster growth and significantly higher yields, with truly spectacular yields per m². 

​

• odourless
• 100% natural
• lightweight
• easy to use
• cost-effective
• safe for people, animals and plants
• for rooms of up to 6m² (min. 0.5m²)
• maximum lifespan: up to 90 days

Instructions for use in English: here*, here* and here*.

CO₂ Boost is a natural product that works in conjunction with light cycles. Since plants absorb CO₂ only when exposed to light, it is recommended to switch off the pump when the light is off. CO₂ Boost should be set to operate in sync with the light cycle. In this case, the maximum product lifespan is up to 90 days!

Application methods:

1. The best method of distribution is to place the end of the hose directly over the tops of the plants, allowing CO₂ to reach the leaves and roots. This is a good method for avoiding issues such as lack of air and ventilation. 
2. If you use a rail system in which the lights move back and forth, attach the hose to the bracket that moves with the light to ensure that all plants are supplied evenly.
3. Another possible use is to attach the hose to the back of a circulation fan. This distributes the natural CO₂ throughout the room.

​Once the bucket has been used, it can be opened and the material inside can be used as compost for your garden.

TechGrow CO₂ generator with 10 burners (LPG) is a powerful, reliable solution for enriching the air with carbon dioxide in grow rooms, greenhouses and professional installations. Designed to maintain optimum CO₂ levels, it significantly accelerates photosynthesis, leading to faster growth, higher yield and better plant quality.

The system runs on propane-butane (LPG) and uses electronic ignition without a pilot flame, providing lower gas consumption and greater operational safety.

With its 10 burners and adjustable output (2, 5, 7 or 10 active burners), the generator can be adapted to the room size and plant needs, making it suitable for both medium and large grow spaces.

⚙️ Key features:

• ✔️ Type: CO₂ generator (LPG – propane/butane)
• ✔️ Power: ~10 kW
• ✔️ 10 burners with adjustment option (2 / 5 / 7 / 10)
• ✔️ Suitable for rooms up to approximately 225 m³
• ✔️ Electronic ignition – no permanent pilot flame
• ✔️ Operates with a 12V adapter
• ✔️ Easy connection to a gas cylinder
• ✔️ Plug & Play – easy installation

? Safety and protection:

• ✔️ Tilt protection
• ✔️ Audible alarm
• ✔️ Stable, reliable operation
• ✔️ Safe design for professional use

? Benefits for plants:

• Raises CO₂ levels to optimum values

⚠️ Important: The generator must be installed suspended, with free airflow underneath for correct operation.

The CO₂ generator increases the CO₂ level in your greenhouse. It makes it possible to supply your greenhouse with additional CO₂ when needed, so that the CO₂ level always reaches the desired value. With the right amount of CO₂ in the area, plants become more active and therefore grow faster. The CO₂ generator operates with electric ignition rather than manual ignition, resulting in lower gas consumption.
