Green House Powder Feeding Grow 500 gr
Green House Powder Feeding Grow 500 gr is the standard format for consistent vegetative-phase nutrition. This mineral powder fertilizer delivers an NPK ratio of 21-5-10 with 2% MgO and a full EDTA-chelated trace element suite. Each gram dissolved in one liter produces an EC of 1.4, yielding 500 liters of precision-dosed nutrient solution from a single package. The powder format eliminates water weight, stabilizer overhead, and shelf-life degradation common in liquid fertilizers. Available at plantandflower.be with fast Belgian delivery.
Green House Grow 500 gr – Consistent Vegetative Nutrition at Scale
Reliable vegetative growth depends on consistent nutrient delivery cycle after cycle. The Green House Powder Feeding Grow 500 gr is the format most hobbyist growers settle on: sufficient volume for a full season of feeding, compact enough to store in any grow space. As part of the Green House Powder Feeding mineral line, it provides a complete nutritional profile specifically calibrated for the vegetative growth stage.
Powder vs. Liquid: The Efficiency Case
Liquid fertilizers typically contain 80-95% water. That means for every liter purchased, as little as 50-200 ml is actual nutrient content. Powder Feeding Grow eliminates this inefficiency entirely: every gram is active ingredient. The practical implications are significant. Storage footprint drops by an order of magnitude. Shipping weight decreases proportionally. Cost per liter of working solution falls dramatically. Additionally, dry mineral powder maintains chemical stability indefinitely when stored properly, while liquid products can precipitate, crystallize, or decompose over time, particularly after repeated temperature fluctuations.
Application Guidelines by Growth Stage
- Seedlings (week 1-2): 0.5 g/L, EC ~0.7. Light feeding to avoid salt stress on undeveloped root systems.
- Early vegetative (week 3-4): 0.75 g/L, EC ~1.0. Gradually increasing as root mass expands and nutrient demand rises.
- Full vegetative (week 5+): 1.0 g/L, EC 1.4. Standard concentration for maximum growth rate and structural development.
- Mother plants: 1.0 g/L continuously. Maintains vigor, leaf thickness, and cutting production capacity over extended periods.
What the Numbers Mean for Your Plants
The 21% nitrogen drives protein synthesis, chlorophyll production, and cell elongation – the three pillars of vegetative growth. The split between nitrate (7.9%) and ammonium (13.1%) nitrogen is deliberate: nitrate is immediately plant-available and promotes upward growth, while ammonium is processed more gradually and encourages compact, branched architecture. The 10% potassium strengthens cell walls against mechanical stress and regulates water movement through stomata. Combined with 2% magnesium as the central atom in every chlorophyll molecule, the formula maximizes photosynthetic output per unit of leaf area.
Transitioning to Bloom
When plants show pre-flowering signals, begin a one-week transition by running Grow at half dose alongside your chosen bloom formula. For short-flowering varieties (8 weeks or less), switch to Short Flowering 500 gr. Supplement with Booster PK+ 500 gr from week 3 of flowering onward to drive fruit and flower production with additional phosphorus and potassium.

How long does 500 gr of Green House Grow last for a typical hobby grow?
At 1 g/L standard dosing, 500 grams yields 500 liters of nutrient solution. For a typical hobby setup with 4-6 plants, this covers approximately 2-3 full vegetative cycles depending on pot size, watering frequency, and vegetative period duration.
Is Green House Grow compatible with all substrate types?
Grow dissolves completely without residue, making it compatible with soil, coco coir, perlite, clay pebbles, rockwool, and all hydroponic systems including NFT, DWC, and drip irrigation. For pre-amended soil, reduce initial dosing by 50% until the existing nutrients are depleted.
What distinguishes Green House Grow from the Hybrids formula?
Grow (NPK 21-5-10) is a dedicated vegetative-phase fertilizer with maximum nitrogen for structural development. Hybrids is an all-in-one formula designed to cover both growth and flowering for varieties with 8-9 week bloom periods. Using Grow separately provides more precise nutritional control by phase.
Does Green House Grow require pH adjustment after mixing?
The resulting pH depends on your source water. After dissolving Grow, measure pH and adjust to 5.8-6.5 for hydro/coco or 6.0-7.0 for soil. The EDTA-chelated micronutrients remain plant-available across a wide pH range, providing a buffer against minor pH fluctuations between feedings.
