Seaweed Biostimulant That Keeps Plants Growing Through Stress
Ecothrive Flourish is an ultra-purified seaweed extract and anti-stress tonic built for growers who push their plants hard. A proprietary refining process strips out the gums and solids that clog drippers and foul reservoirs, leaving a fully soluble, highly stable biostimulant that stays workable in a tank for weeks. It feeds the plant's own stress-response machinery rather than simply adding NPK.
Key Benefits
- Raises stress tolerance so plants keep growing through heat spikes, cold nights and high light intensity
- Improves germination and rooting, getting seeds and cuttings established faster
- Drives vegetative vigour for denser, greener growth through the veg stage
- Supports flower development and more consistent quality through bloom
- Root feed or foliar spray — one bottle covers both application routes
- Reservoir-stable and clean enough for soil, coco and hydroponics alike
- Runs happily under LED, where light stress is typically highest
Heat Stress and Stalled Growth Under Hard Light
Plants under intense LED or through a summer heatwave stop growing long before they show visible damage — energy goes into survival instead of yield. The natural cytokinins, betaines and alginates in Flourish support the plant's own stress response, so growth continues through conditions that would otherwise cause excessive stretch, weak roots and poor nutrient uptake.
How to Use
- Root feed: 1–2 ml per litre of nutrient solution at every feed, through veg and bloom
- Foliar spray: 2 ml per litre, applied to run-off with lights off or dimmed
- Propagation: 1 ml per litre as a light drench for cuttings and seedlings
- Add to the reservoir after base nutrients, then check and correct pH
- Shake before use; store cool and out of direct sunlight
