Green House Powder Long Flowering 125 gr
Green House Powder Feeding Long Flowering 125 gr delivers a targeted NPK 18-12-18 mineral formula for varieties with flowering periods of 10 weeks or more. The 12% phosphorus concentration, the highest in the Powder Feeding range, supports extensive root network development and sustained ATP-driven energy metabolism across prolonged bloom cycles. The balanced macro ratio maintains vegetative vitality throughout extended flowering. Calcium-free for water hardness flexibility. Order from plantandflower.be with fast Belgian delivery.
Green House Powder Feeding Long Flowering 125 gr – Phosphorus-Rich Nutrition for Extended Bloom Cycles
Varieties with 10+ week flowering periods operate under a fundamentally different metabolic timeline than rapid finishers. The extended generative phase demands sustained phosphorus for root network expansion, higher nitrogen to maintain vegetative processes alongside flowering, and consistent potassium for progressive flower development. Green House Powder Feeding Long Flowering addresses this profile with the highest phosphorus concentration in the mineral lineup. The 125 gr format provides a controlled evaluation pathway.
Why 12% Phosphorus Matters for Long-Cycle Varieties
Phosphorus is the energy currency of plant metabolism. As a structural component of ATP, DNA, RNA, and membrane phospholipids, it drives every cell division, every energy transfer, and every biosynthetic reaction. Varieties flowering for 10+ weeks sustain these processes significantly longer than 8-week finishers. Their root systems must expand deeper and wider to support extended nutrient and water uptake. At 12% P₂O₅, Long Flowering delivers double the phosphorus of Short Flowering (6%) and substantially more than Hybrids (7%). The measurable outcome: more extensive root architecture, sustained energy availability, and maintained flower production through weeks 10, 12, and beyond.
Guaranteed Analysis: NPK 18-12-18
- Nitrogen 18% (10% nitrate + 8% ammonium): the highest N after the Grow formula. The elevated ammonium fraction (8% vs 5% in Short Flowering) supports root zone assimilation in neutral to slightly acidic substrates.
- Phosphorus 12% (P₂O₅): range maximum. Drives root expansion, cellular energy metabolism, and sustained biosynthesis over the extended cycle.
- Potassium 18% (K₂O): solid foundation for flower construction, sugar transport, and stress resilience across the prolonged bloom phase.
- MgO 2% + EDTA-chelated trace elements: chlorophyll optimization and full enzymatic cofactor supply.
Application Protocol
Standard dose: 1 g/L throughout the full cycle. Start seedlings at 0.5 g/L. In soil, alternate nutrient feeds with plain water. In coco and hydro, feed every irrigation. Long Flowering covers the complete lifecycle as a standalone product. Add Booster PK+ from flowering week 4-5 for supplemental PK during peak generative demand. For soft or RO water, supplement with Calcium from the start of the cycle.
Positioning Within the Range
Long Flowering targets sativa-dominant genetics and slow-maturing hybrids requiring 10+ weeks of bloom. For varieties finishing in 8 weeks or less, Short Flowering 125 gr with its 26% potassium is the better match. For the 8-10 week window, Hybrids provides an optimized intermediate profile. Selecting the correct formula based on flowering duration is the simplest way to match nutrition to genetic requirements.

What is the difference between Long Flowering and Hybrids?
Long Flowering (NPK 18-12-18) provides more phosphorus (12% vs 7%) and nitrogen (18% vs 15%) for varieties with 10+ week bloom periods. Hybrids (NPK 15-7-22) maximizes potassium and magnesium for 8-10 week varieties. Select based on your specific variety's flowering duration.
Why does Long Flowering have the highest phosphorus in the range?
Long-flowering varieties develop more extensive root systems and maintain intensive metabolic activity for 10+ weeks. Phosphorus, as a structural component of ATP and nucleic acids, is consumed at proportionally higher rates over these extended cycles. The 12% P₂O₅ meets this sustained energy and growth demand.
Is Long Flowering suitable for sativa-dominant varieties?
Long Flowering is specifically formulated for sativa-dominant genetics and slow-maturing hybrids. Their 10-14 week bloom periods benefit directly from the elevated phosphorus for root development and the 18% nitrogen that maintains plant vitality across the extended cycle.
How many liters does the 125 gr package produce?
At standard 1 g/L dosing, 125 grams yields 125 liters. Long-flowering varieties consume more solution per cycle due to their extended timeline. For 2-3 plants, this covers one evaluation cycle. The 500 gr format offers better economics for regular cultivation.
