Hi Growmies✌️💚🌱 I am looking...

Pot looks ceramic or plastic, limiting oxygen. Sand can act as an effective oxygen barrier, particularly when combined with other materials in a layered system designed to control water infiltration and oxygen diffusion. This is because sand's coarse nature and the resulting spaces between grains can limit the passage of oxygen through the soil. Oxygen readily diffuses through air, but its diffusion through water is significantly slower (up to 10,000 times slower). Sand is creating a moisture-retaining layer (MRL), hindering oxygen diffusion. God bless those hydroton pebbles. Phosphorus is an essential plant nutrient, and its availability in the soil is strongly linked to the presence of oxygen. Plants primarily absorb phosphorus as phosphate (PO4), and oxygen is a key component of this molecule. Furthermore, the availability of phosphorus in the soil can be impacted by factors like soil aeration and temperature, which in turn affect the oxygen supply to the roots. Phosphorus uptake in plants is most critical during the early stages of growth, particularly within the first few weeks of plant development. Young plants actively growing tissues have a high demand for phosphorus. They may absorb up to 75% of their total phosphorus requirements within the first few weeks of vegetative growth, with studies indicating in controlled environments up to 51% of uptake happening overnight, primarily in the first few hours or early nightfall. Anaerobic respiration, unlike aerobic respiration, doesn't utilize oxygen as the final electron acceptor in the electron transport chain. This results in a significant drop in the amount of energy (ATP) produced, which is necessary for various plant functions, including growth, nutrient uptake, and maintenance of cellular processes. In the absence of oxygen, cannabis produces byproducts like ethanol and lactic acid during anaerobic fermentation. These byproducts can be toxic to the roots and inhibit their function, the lack of oxygen in the plant medium leads to a decrease in pH due to the production of carbon dioxide during anaerobic respiration and impaired pH regulation within the plant. You can survive weeks without food. You can survive days without water. You can survive minutes without oxygen. You can survive 16 seconds without ATP.
