All elements are present and will remain available to plants through varying conditions of usage.It is highly concentrated and will make up to 100 times its volume of working solution. Formulex is complete.It is designed for hydroponic applications where every nutrient element must be supplied in solution.It is versatile. It is suitable for hydroponic or soil cultivation and especially recommended for foliar feeding.Formulex is meticulously formulated to express a pH of 6 when made up with tap water. Formulex: How do you use it? You can use Growth Technology Formulex on young plants, seedlings and cuttings until they're ready for budding. Formulex can be used on any plant, in any media and with any kind of grow system. Use Growth Technology Formulex once per week for hand-watering, or every other reservoir change in hydro when needed. Before using, shake the bottle thoroughly. Add 5ml to the feed-water for soil and stir well. Hydroponics: Use 10ml per litre reservoir water. Mix well. Add 5ml/litre water to foliar feed and stir well. You should spray your plants top-to-bottom. Make sure the bottoms as well as the tops are wetted. Make sure that no liquid comes in contact with the grow lamp. Spraying your plants in low light conditions is the best time. This will help to prevent leaf-burn from excessive light striking wet leaves.

  • Growth Technology- Liquid Oxygen
    Growth Technology- Liquid Oxygen

    Growth Technology - Liquid Oxygen Growth Technology - Liquid Oxygen provides your plants’ roots with a strong source of extra oxygen to help roots to thrive. Liquid Oxygen also creates a hostile environment for root diseases. How Liquid Oxygen Works Growth Technology - Liquid Oxygen is a strong solution of hydrogen peroxide (H2O2). When it is mixed into your nutrient solution the hydrogen peroxide breaks down into a molecule of water (H2O) plus an oxygen atom (O). The oxygen atom will then join another oxygen atom and form a stable dissolved O2 molecule which “oxygenates” the water or it will attack microbes or other organic molecules and break them down. In this way, Growth Technology – Liquid Oxygen creates a highly oxygenated and sterile root-zone. Roots thrive in a highly oxygenated solution and the lack of root-diseases ensures they do not get root-rot.The sterile solution that this product creates means that it is unsuitable for organic growing or for use with other products which contain or require friendly microbes. Peroxide will kill these microbes along with the unfriendly types, making this product unsuitable for use in these grow situations.

  • Does the heating air make you tired and cause poor air quality?

    Heating air can make you feel tired and cause poor air quality if the heating system is not properly maintained. Dust, allergens, and other particles can accumulate in the heating system and get circulated throughout the air, leading to poor air quality. Additionally, dry air from heating systems can cause dehydration and lead to fatigue. It is important to regularly clean and maintain heating systems to ensure good air quality and to minimize the impact on your health. Using a humidifier can also help to improve air quality and reduce the drying effects of heating systems.

  • What is the collaboration between Travis Scott and Nike Air Max 1?

    Travis Scott collaborated with Nike to release a special edition of the Nike Air Max 1 sneaker. The collaboration resulted in a unique design that featured Scott's signature style and branding elements. The shoe was highly anticipated by fans of both Travis Scott and Nike, and it quickly became a sought-after collector's item in the sneaker community.

  • What is the efficiency of an ideal hot air engine?

    The efficiency of an ideal hot air engine is determined by the Carnot efficiency formula, which is 1 - (Tc/Th), where Tc is the temperature of the cold reservoir and Th is the temperature of the hot reservoir. The efficiency of an ideal hot air engine can approach 100% as the temperature difference between the hot and cold reservoirs increases. However, in practice, achieving such high efficiencies is challenging due to losses from friction, heat transfer, and other inefficiencies in the system.

  • Have you ever had problems with air quality?

    As an AI, I do not have the ability to experience air quality issues. However, I am aware that poor air quality can have serious health implications for humans, such as respiratory problems and exacerbation of existing conditions like asthma. It is important to monitor air quality levels and take necessary precautions to protect our health and well-being.

  • Growth Technology pH Down
    Growth Technology pH Down

    PH Down  Growth Technology pH DOWN contains orthophosphoric acid (H3PO4). The concentration is 81%, which is very strong so handle with care. Some other products on the market are considerably weaker, so check the concentration before buying. This is a very dense liquid and should feel much heavier than water. What pH Down Does The concentrated phosphoric acid pH Down can be added to almost all liquids to lower the pH. It is important to maintain a pH range when growing plants using hydroponics and aeroponics. Each plant has its own requirements, but most require a pH of between 5.5 and 6.5. To maintain this pH level, pH Down can be added to the nutrient solution sparingly. How to use pH down PH Up and Down can react explosively to each other if they come in contact. Even small amounts of pH Up or pH Down could explode. Both pH Up and pH Down are corrosive, and can cause skin irritation and even burns. Use with caution and keep out of reach of children.High Quality pH adjustment in a bottle. Features CRC cap for safety. Highly concentrated so only a little is needed. Always dilute prior to use.

  • Can the efficiency of photosynthesis actually be increased by high air pressure?

    High air pressure can potentially increase the efficiency of photosynthesis by allowing plants to take in more carbon dioxide, which is a key component in the process. However, there are limits to how much pressure can be increased before it becomes detrimental to plant growth. Additionally, other factors such as temperature, light intensity, and nutrient availability also play a significant role in the efficiency of photosynthesis.

  • Why does the air quality worsen in humid weather?

    Air quality worsens in humid weather because the moisture in the air can trap pollutants and prevent them from dispersing. This can lead to an accumulation of pollutants such as dust, pollen, and mold spores, which can degrade air quality. Additionally, high humidity can also promote the formation of ground-level ozone, a harmful pollutant that can exacerbate respiratory issues. Finally, humid weather can also create conditions that are conducive to the growth of bacteria and other microorganisms, further contributing to poor air quality.

  • Is the sound quality of the MacBook Air bad?

    The sound quality of the MacBook Air is generally considered to be good for a laptop of its size. It has stereo speakers that provide clear and balanced sound for everyday use such as watching videos, listening to music, or video conferencing. While it may not have the same level of audio quality as larger laptops or external speakers, the MacBook Air's sound quality is still impressive for its compact design.

  • Is the air quality poor with night storage heaters?

    Night storage heaters do not directly impact air quality, as they do not produce any emissions or pollutants. However, poor air quality can be a concern in homes with night storage heaters if they are not properly maintained or if the insulation in the home is inadequate. Dust and other allergens can accumulate in the heating system and be circulated throughout the home, potentially impacting air quality. Regular maintenance and proper insulation can help mitigate these issues and ensure good air quality in homes with night storage heaters.
