Green Planet Horti Grow
Horti Grow is Green Planet’s premium dry base fertiliser, specifically designed for the vegetative stage. With an NPK ratio of 8‑11‑21, plus magnesium, sulphur, and a full suite of micronutrients, it delivers strong, vibrant growth and prepares plants for a successful transition into flowering. The formula is fully water‑soluble, pH‑stable, and free from fillers, ensuring clean, reliable feeding that leaves no sediment or residue, perfect for manual mixing, stock tanks, or automated dosing systems.
By fuelling vigorous green growth, Horti Grow promotes robust stems, dense foliage, and healthy root systems. Magnesium and sulphur drive photosynthesis and chlorophyll production, while the added micronutrients ensure plants receive balanced nutrition for every growth stage. This makes Horti Grow not only efficient but also scalable, fitting seamlessly into both small‑scale grows and large commercial operations.
Tested extensively in real‑world conditions, the Horti Line is engineered for precision and reliability. Horti Grow’s clean solubility makes it ideal for hydroponics, coco, and soil applications, delivering predictable results without clogging irrigation lines or emitters. Integrated into the HORTI Feeding Program, it provides stage‑specific performance that growers can trust.
Whether you are hand‑mixing nutrients or managing large‑scale fertigation systems, Horti Grow is a dependable base fertiliser that supports lush, resilient plants and sets the stage for heavy yields during bloom.

- This creates a concentrated stock solution. Always prepare each HORTI product in its own stock tank to avoid precipitation.
Dosing the Reservoir
- Inject or manually dose the concentrate into the main reservoir; circulate thoroughly for even distribution.
- After dosing, check and adjust EC and pH to target.
Application
- Use during the vegetative stage only.
- Apply as a base nutrient in soil, coco, or hydro systems.
- Monitor and adjust EC/PPM and pH after adding concentrate to the reservoir.
- Transition to Horti Bloom and Horti Late Bloom during flowering.
- For best results, always use in conjunction with Horti Cal to maintain proper calcium balance.
Store sealed in a cool, dry, ventilated place. Protect from humidity and temperature extremes.
