Growth Sarthi — Bio-NPK Liquid

Growth Sarthi is not a chemical fertilizer; it's a living microbial Bio-NPK tonic made of beneficial soil bacteria. Instead of delivering a one-time chemical dose, Azotobacter, Azospirillum, phosphate-solubilising bacteria and potash-mobilising bacteria work in the soil to unlock nitrogen, phosphorus and potassium that are already there or in the air, gradually rebuilding soil life between feeds.

Three bacterial groups do the work in Growth Sarthi: Azotobacter and Azospirillum fix nitrogen from the air, phosphate-solubilising bacteria (PSB) unlock phosphorus already locked in potting mix, and potash-mobilising bacteria (KMB) free up potassium. Because these are living cultures, not a one-time chemical dose, they keep working between feeds rather than delivering a single feast-then-famine hit.

Mix 5ml of Growth Sarthi per litre of water. A standard bottle cap holds about 5ml, so one full cap per litre of water gives you the correct dose without needing a separate measuring cylinder. Shake the bottle well first, since the live cultures settle between uses, before measuring and applying.

Apply Growth Sarthi every 10-15 days through the active growing season. Applying it more frequently won't speed things up, because the bacteria need that window of time to establish themselves in the soil and do their work. Steady, spaced-out dosing is what builds up the microbial population, not more frequent applications.

Denser new growth and steadier flowering typically show up within 3-4 applications of Growth Sarthi, roughly around 6 weeks, as the microbial population builds up in the soil. This isn't an instant chemical response; it reflects live bacteria establishing themselves in the soil and gradually unlocking nitrogen, phosphorus and potassium for the plant.

Yes, Growth Sarthi's suitable-use list includes indoor plants and seedlings & all pots, alongside vegetables, flowering plants, fruit trees, lawns and kitchen gardens. As a 100% organic, chemical-free living-microbe product, it's formulated to be gentle enough for young seedlings while still building soil life the same way it does for established plants.

No, the label specifically warns not to mix Growth Sarthi with bleach, disinfectants or other chemicals. Growth Sarthi contains living bacterial cultures, and these chemicals would work against the microbes before they reach the soil, so keep its application separate in time and equipment from any disinfecting or cleaning you're doing around your pots.

Apply Growth Sarthi during the cool hours of morning or evening, and avoid spraying in harsh sunlight. The label notes this matters because harsh sun stresses both the plant and the live bacteria in the formula, so cooler light conditions give the microbial cultures a better chance of establishing successfully in the soil.

Use Growth Sarthi within 6 months of opening, as stated on the label. Because it contains living bacterial cultures rather than stable chemical compounds, store the bottle in a cool, dry place away from direct sunlight, and check the printed date on your bottle for the manufacturing details.

The CFU/ml figure is the guaranteed total viable count of live bacteria in Growth Sarthi - at least 5x10^8 CFU/ml, formulated to a pH of 5.0-7.0. It's real batch data from the manufacturer, Gilehri Organics (Mfg. Lic. No. 517/Bio/23), confirming how many living microbial cells are actually in each millilitre you apply.
