A fertiliser with a complete range of nutrients, designed for hydro/coco. This product has all the necessary macro- and micronutrients for abundant flowering. The high-quality components will be fully absorbed without any residue.

• Total N-P-K: 5-2-6
• Stimulates maximum flowering
• Increases strength and vigour throughout the flowering phase
• EC levels up to 2.3
• Suitable for any irrigation system
• Optimal plant absorption

Plants absorb essential elements from air and light, as well as from nutrients in the soil. The plant's roots and leaves are the main components that absorb these elements. It is essential that plants receive not only sufficient nutrients, but also the right ratio. This prevents nutrient deficiency or toxicity (when the plant receives too many nutrients) and promotes maximum growth and health.
During the flowering stage, the plant prepares to pollinate. Photoreceptor proteins in the plant indicate when to flower. At this point, the plant begins to produce flowers so that pollen can fertilise the female plant. This process costs the plant a great deal of energy. To stimulate the plant during the flowering stage, a balance of nitrogen, potassium and phosphorus is needed. This will keep the plant strong and healthy throughout the flowering stage.
Original Bloom Hydro / Cocos A + B is a perfectly blended two-part fertiliser containing potassium, nitrogen and phosphorus to stimulate maximum growth and prevent disease. Original Bloom Hydro / Cocos A + B is also optimised to reach EC levels of 2.1 - 2.3 (variations are possible) for an even better result!

Dosage:

• 250-350ml per 100 litres of water

User instructions:

• Do not ingest!
• Keep out of reach of children!
• In case of contact with eyes, rinse immediately with plenty of water and seek medical advice!
• Wear protective clothing - the use of gloves is recommended!

Liquid Oxygen - the well-known product for cleaning and oxidising hydroponic* systems.

• contains 17.5% hydrogen peroxide (H₂O₂)
• adds extra pure oxygen ions to the nutrient-solution reservoir / container - regular use leads to increased growth rates
• helps control root diseases and pathogens in the reservoir - continuous growth means healthier plants
• can be used at a higher concentration to clean and sterilise hydroponic* systems between crops, as well as pots and benches in the greenhouse or elsewhere

Instructions for use here and Safety Data Sheet here !

Liquid Oxygen contains hydrogen peroxide (H₂O₂), which is a highly unstable molecule. It rapidly breaks down in the nutrient-solution container, releasing a free oxygen atom. This oxygen atom is extremely reactive and will attach to another atom to form a stable oxygen molecule or attack a nearby organic molecule, such as a virus or fungal spore. Liquid Oxygen can eliminate existing diseases and help prevent future ones.

Adding Liquid Oxygen to the nutrient reservoir daily will stimulate the plant and increase nutrient uptake, resulting in faster growth rates. In plants, the extra oxygen supplied will significantly stimulate protein production at cellular level. This will greatly improve the photosynthetic process, resulting in plants with larger leaves, thicker stems and shorter internodes. Plants will be stronger and their leaves darker, allowing light to be captured more efficiently and further improving the photosynthetic response.

Health and Safety:

• Always wear gloves and safety goggles when handling aggressive liquids!
• Always store in locked cabinets!
• KEEP OUT OF REACH OF CHILDREN!
• pH UP and pH DOWN must be diluted before use — see the link above for Instructions for handling aggressive liquids!

A complete nutrient fertiliser designed for hydro/coco. This product contains all the essential macro- and micronutrients needed for vigorous growth. Its high-quality components are fully absorbed without residue.

• Total N-P-K: 4-2-6
• Stimulates maximum growth
• Increases strength and resilience throughout the growth phase
• EC levels up to 2.0
• Suitable for any irrigation system
• Optimal plant absorption
  

Plants absorb essential elements from air and light, as well as from nutrients in the soil. A plant's roots and leaves are the main components that take up these elements. It is essential that plants receive not only enough nutrients, but also the right balance. This prevents nutrient deficiency or toxicity (when the plant receives too many nutrients) and promotes maximum growth and health.
During the growth phase, the plant is at its most vulnerable. Diseases related to fungi and bacteria pose a real threat to underdeveloped roots and leaves. To help the plant develop during the growth phase, the right blend of potassium, nitrogen and phosphorus is needed to maintain the maximum growth rate. This will make and keep the plant vigorous and strong throughout the growth phase.
Original Grow Hydro / Cocos A + B is a perfectly balanced two-part fertiliser containing potassium, nitrogen and phosphorus to promote maximum growth and prevent disease. Original Grow Hydro / Cocos A + B is also optimised to reach EC levels of 1.8–2.0 (variations are possible), for even better results!
