Running HGV Growth Formula Through Vegetative Stage
HGV Nutrients Growth Formula 3-6-22 is a dry ready-to-mix water-soluble blend that pairs with HGV Base Formula 14.5-0-0 to make a complete vegetative feed. The jug ships dry. You fill it to the green Fill Line, shake vigorously for 30 seconds, wait a minute, then shake again. Top off with two cups of warm water, shake once more, and the powder dissolves into a stable liquid concentrate. Dose at 30 mL of Growth plus 15 mL of Base per gallon, then pH to 5.6–5.8 for hydro or coco and 6.0–6.2 for soil. The dry-in-jug format keeps shelf life long; no leak-and-degrade cycle the way liquid base+grow lines have when stored at room temp.
Three-Part Dry Nutrient System for Hydro, Coco, and Soil
The three-part dry nutrient system is intentionally lean — Base, Growth, and Flowering, no additives or supplements layered on top. During veg, growers run the 30 mL Growth + 15 mL Base ratio at one EC from transplant through the last week before flip. The swap to Flowering happens on day one of 12/12 without changing the Base dose. The 1-gallon jug yields 126 gallons of finished veg feed and the 2.5-gallon jug yields 315 gallons. A single Base jug pairs with two Growth or Flowering jugs at either size. Nitrate-only nitrogen with 0.15% chelated iron keeps the salt index low across rockwool, coco, and peat-based soilless mixes.
Key Features
- NPK 3-6-22: 3% Nitrate-N, 6% P₂O₅, and 22% K₂O front-load structural growth and root mass through veg without ammoniacal-N burn risk.
- Dry-In-Jug Format: The powder converts to a stable liquid concentrate inside the jug after a fill-and-shake — no leaks in transit, long shelf life on the shelf.
- 30 mL/gal Dilution: Pairs with 15 mL/gal Base Formula; the 1-gal jug yields 126 gallons of veg feed and the 2.5-gal yields 315 gallons.
- Chelated Iron + Magnesium: 0.15% chelated iron and 2.5% magnesium, plus boron and molybdenum, cover trace requirements without a separate Cal-Mag.
- Universal Media Compatibility: Mixes cleanly into DWC, NFT, ebb-and-flow, drip, rockwool, coco, peat-based soilless, and soil at 5.6–5.8 pH (hydro/coco) or 6.0–6.2 (soil).
