Biogreen CO2 Tablets

Biogreeen CO2 Tablets are effervescent tablets containing potassium hydroxide and potassium carbonate. Carbon dioxide (CO2) is a powerful gaseous fertiliser. More CO₂ in the air means more plant growth. The plant extracts the required CO₂ from the air, which through photosynthesis in the leaves is converted into sugars and oxygen.

• 100 tablets
• CO₂ dissolves in water
• adding CO₂ reduces pH
• the amount of CO₂ dissolved in water in this form also depends on the concentration and pH of the water
• water obtained through water-distribution systems is released into dissolved CO₂

CO₂ is the most important element for all living organisms. Carbon (C) and oxygen (O₂) are two of the most important elements for living organisms, in addition to water, light and nutrients needed for plant growth. Therefore, CO₂ is one of the basic nutrients. The plant extracts the necessary CO₂ from the air through photosynthesis in its leaves, which is then converted into sugars, carbohydrates, cellulose and oxygen. The plant releases oxygen into the air and uses a small portion of it for respiration; the sugars are used as nutrients. The plant consists of 90% water, 9.6% assimilated carbohydrates (such as cellulose in the cell wall) and only 0.4% inorganic material. Other substances such as NPK, vitamins, spores and minerals are also very important for the plant’s various functions.

Directions for use:

• 1 tablet dissolves in 200L of  water in 90 seconds.
• Active for 48h after dissolving.
• Does not affect the EC value.

CO₂ percentage in the air (in a greenhouse):

• completely blocked photosynthesis: 100 ppm 0.010%
• the plant still respires but does not photosynthesise: 150 ppm 0.015%
• normal atmosphere (natural value): 340 ppm 0.034%
• optimal for mushrooms: 550 ppm 0.055%
• optimal photosynthesis: 1200 ppm 0.120%
• lethal for plants: 10000 ppm 1%

In a greenhouse, the concentration of CO₂ is much higher in the morning than in the afternoon and evening because plants do not photosynthesise at night, but respiration continues.

How do you supply plants with CO₂?

• Various systems are available. A very easy method is using effervescent tablets. One component of these tablets is active oxygen. This oxygen is released as soon as the tablet dissolves.
• 1 5-gram tablet provides 30% (1.5 g) CO₂ and 1.5% (0.075 g) active oxygen. The tablets dissolve completely without residue.
• Citric acid and carbonates react very quickly on contact with water. During this reaction, CO₂ is released. In addition, many substances are released whose effect is very positive for the plant’s energy metabolism.
