Hardens flowers in the last stretch rather than growing them
Green Planet Dense is a soluble powder used in late flower to firm and harden what the plant has already built. Where a bulking additive works through the middle weeks, Dense works at the end, combining phosphorus and potassium with silica and magnesium to tighten structure.
Key Benefits
- Late-flower specific - aimed at the final weeks, so it complements a bulking additive rather than duplicating it
- Silica for structure - tighter, harder flowers that hold their shape after drying
- Soluble powder - no water freight in the product, which is why the dose per litre is so small
- Magnesium included - keeps leaf colour while phosphorus and potassium run high
- Works with any base feed - mineral or organic
Flowers that soften and shrink on the dry
A flower that feels firm on the plant and collapses on the drying rack was never structurally dense - it was holding water. Silica and potassium in the last weeks build the cell wall material that survives drying, so what you cut is closer to what you jar.
How to Use
- Last 3 weeks of flower: 1 to 2 g per litre, once a week
- Dissolving: mix into warm water and stir until fully clear before adding to the reservoir
- Taper: stop with the final flush, about a week before harvest
- Water only: GreenPlanet dose Dense separately from the feed programme - no base nutrient goes in that watering
- Media: soil, coco and hydroponics
