Green House Powder Feeding Hybrids 125 gr
Green House Powder Feeding Hybrids 125 gr is a single-formula mineral powder fertilizer with NPK 15-7-22 and 6% MgO, engineered to cover the full lifecycle of hybrid varieties with 8-10 week flowering periods. The urea-free formulation eliminates pH instability in all substrates. Elevated magnesium and sulfate concentrations drive terpene, essential oil, and flavonoid biosynthesis. At 1 g/L dosing, this 125 gram package yields 125 liters of complete nutrient solution. Order from plantandflower.be for fast Belgian shipping.
Green House Powder Feeding Hybrids 125 gr – Full-Cycle Mineral Nutrition for Hybrid Genetics
Multi-product feeding programs introduce complexity, dosing errors, and product interaction risks. Green House Hybrids eliminates these variables with a single-formula approach covering vegetative growth through harvest. Part of the Green House Powder Feeding mineral line, the 125 gr format provides a low-risk evaluation pathway for growers benchmarking this system against their current nutrient regimen.
Formula Specifications
- NPK 15-7-22 + 6% MgO: balanced macro ratio optimized for hybrid varieties with 8-10 week flowering periods. The 15% nitrogen supports vegetative structure without delaying flower initiation. The 22% potassium drives generative development.
- Urea-free nitrogen: exclusively nitrate and ammonium forms in harmonized ratio. Eliminates urease-mediated pH fluctuations in substrate and nutrient solution.
- 6% magnesium oxide: triple the MgO concentration of the Grow formula. Magnesium is the central atom in chlorophyll and a required cofactor for terpene and flavonoid biosynthesis pathways.
- Full EDTA-chelated micronutrient package: Fe, Mn, Zn, Cu, B, Mo available across pH 4.0-8.0.
Operational Simplicity
Dose at 1 gram per liter throughout the entire cycle. Start at 0.5 g/L for seedlings and freshly rooted cuttings, scaling to full concentration within 7-10 days. The same product and dosing rate applies from vegetative growth through flowering and fruit set. This single-formula approach reduces inventory requirements, eliminates transition timing errors, and maintains nutritional consistency across the full lifecycle. For enhanced flowering, optionally add Booster PK+ from week 3 of flowering.
Terpene and Secondary Metabolite Production
The elevated magnesium and sulfate content in Hybrids directly supports secondary metabolite biosynthesis. Terpenes are produced via the mevalonate and MEP pathways, both of which require magnesium as an enzymatic cofactor. Flavonoids follow the phenylpropanoid pathway, similarly magnesium-dependent. The practical result: growers consistently report enhanced aromatic profiles and greater olfactory complexity compared to standard NPK formulations with lower magnesium content. The 22% potassium further supports these pathways by maintaining cellular turgor and enzymatic activity during peak metabolic demand in late flowering.
Hydroponic Compatibility
The urea-free composition makes Hybrids the preferred choice for hydroponic systems. In recirculating setups (NFT, DWC, ebb-flow), urea-based fertilizers cause unpredictable pH spikes as urease converts urea to ammonia. Hybrids delivers all nitrogen in immediately plant-available ionic forms, resulting in predictable pH behavior and reduced corrective intervention. The powder dissolves completely without sediment, preventing emitter and line blockages.

What is the difference between Green House Hybrids and Short Flowering?
Hybrids (NPK 15-7-22, 6% MgO) targets hybrid varieties with 8-10 week flowering, emphasizing magnesium for terpene production. Short Flowering (NPK 16-6-26) is optimized for rapid finishers under 8 weeks with higher potassium. Select based on your specific variety's flowering duration.
Do I need a separate grow fertilizer when using Hybrids?
Hybrids is designed as a complete single-formula solution. No separate vegetative fertilizer is required. The 15% nitrogen provides sufficient support for structural development during the vegetative phase while maintaining the nutritional balance needed for smooth transition into flowering.
Why does the Hybrids formula exclude urea?
Urea requires enzymatic conversion by urease before plants can absorb it, generating ammonia that spikes pH unpredictably. This is particularly problematic in hydroponic systems. Hybrids uses only nitrate and ammonium nitrogen in directly plant-available forms, ensuring stable pH and immediate nutrient access.
Can Green House Hybrids 125 gr be used with calcium nitrate for RO water?
Green House recommends calcium supplementation when using RO or soft water. Calcium nitrate or the dedicated GHF Calcium additive can be used. Always dissolve calcium products separately before combining with the Hybrids solution to prevent calcium phosphate precipitation.
