😍 Beauty. Empty water with NPK raw enzymes, amino and humic/fulvic. Checking the EC of the pot, ranges vary but overall sitting around d 1.2-1.6ms/cm. I can notice tips on one, ever so slightly yellow, hints that ec is on the line.
See how long she can go with just water. So far, so good. They are at that size when the growth snowball really starts to pick up. Upped ppfd, first sign of flower showing on 1 plant. Applied a fair bit of IR, which has stretched the stems; they know if they want to reach the high ppfd they need for flower, then they need to stretch accordingly.
Plant perception allows plants to sense the direction, intensity, quality, and duration of light, using this information to direct growth, optimize photosynthesis, and adjust development. This ability to "see" light and respond accordingly is a fundamental survival mechanism.
The interaction between microorganisms and the plant rhizosphere creates an active environment that directly contributes to soil electrical conductivity (EC), facilitating nutrient availability and, consequently, enabling better plant growth. A healthy, microbially active rhizosphere acts as a living, conductive bridge that converts locked-up resources into bioavailable, charged particles (ions) that the plant can directly use to grow. Microbes break down organic matter and minerals, releasing ions (N, P, K, etc.) slowly and in alignment with plant needs. Unlike synthetic fertilizers that dump a high concentration of salts at once (causing instant, great EC osmotic shock), microbial processes provide a steadier stream of nutrients. Beneficial microbes produce osmolytes, antioxidants, and signaling molecules (like auxins and ACC deaminase) that help plants manage drought, salt, and temperature stress. Microbial exopolysaccharides (EPS) create hydrated biofilms around roots, maintaining a more stable water environment. If an excessive amount of soluble nutrients or salts is added (e.g., heavy compost, manure, or excessive mineral amendments), the total dissolved solids can still exceed the plant's tolerance threshold. Intense evaporation, drought, or extreme heat can concentrate salts in the soil solution regardless of how active the microbes are. (Balance). The ability of microbes to buffer the soil is finite. If the input exceeds the biological processing speed, osmotic stress can occur. This is where high CEC comes in useful. Because of this active exchange, the plant creates a localized chemistry that favors what it needs: If the plant needs calcium, it increases exudates that favor calcium solubilization and exchange. The plant can alter the pH immediately around the roots to make specific nutrients more available while locking up others. It doesn't need. The high CEC acts as a buffer against over-fertilization or pH swings. Instead of nutrient antagonism (where too much of one thing blocks another), the microbial activity helps balance nutrient availability. In a high-CEC organic system, the plant acts as a manager, utilizing microbes and root chemistry to pull exactly what it needs from the "bank" of soil nutrients. Nature knows best. I let her feed herself now.
If a leaf is photosynthesizing, it makes ATP (via light reactions) and sugars. If a root is respiring, it burns sugars to make ATP for itself. They do not share a common, transferable "pool." While you don't get a "bigger ATP pool" by adding root ATP to leaf ATP, growing organically allows for better energy allocation. In organic systems, mycorrhizal fungi and bacteria break down nutrients. This requires less direct energy expenditure from the plant to seek out raw minerals compared to hydroponics/synthetic, where the plant might have to push harder roots to find uptake points. Healthy, microbe-rich roots need less energy for defense and can focus on absorption. Plants send sugars (made in leaves) down to roots to feed microbes, which in turn bring back nutrients/salt ions to create a EC of 0.5ms/cm. This symbiotic loop means the plant spends less energy on acquiring nutrients, leaving more energy available for building biomass.
Leaves make Glucose (Sugar) via Photosynthesis. Sugars travel to the roots. Roots use that sugar to fuel respiration to gain nutrients. Nutrients travel back up to fuel more Leaf growth.
Organic growing doesn't create a larger combined ATP pool; it creates more efficient energy usage and resource allocation. Because the plant isn't wasting energy fighting for nutrients or managing osmotic stress from synthetic salts, it has more metabolic energy left over to put into growth.
High Transpiration Rate. Stronger Mass Flow. More water/nutrients to roots. Increased uptake.
It is a "pull" system that acts as the primary conveyor belt for plant nutrition.
