Ecothrive Flourish is a concentrated seaweed biostimulant designed to support plant growth, nutrient uptake and tolerance to environmental stress throughout the growing cycle.
Made from highly refined Ascophyllum nodosum seaweed extract, Flourish provides naturally occurring bioactive compounds rather than acting as a conventional fertiliser. It can be used alongside a normal nutrient programme in soil, coco and hydroponic systems.
Key features
- Concentrated seaweed extract: made from Ascophyllum nodosum seaweed.
- Natural biostimulant: provides bioactive seaweed compounds rather than functioning as a base nutrient.
- Suitable for soil, coco and hydro: refined for use across a wide range of growing systems.
- Reservoir stable: highly filtered and fully soluble for use in nutrient tanks and automatic irrigation systems.
- Root or foliar application: can be added to irrigation water or applied as a foliar spray.
- Low application rate: use at 0.25 to 0.5ml per litre through the root zone.
What is Ecothrive Flourish?
Flourish is an extract of Ascophyllum nodosum, a species of brown seaweed used in horticultural biostimulants. Its value comes from seaweed-derived bioactive compounds rather than from supplying significant NPK nutrition.
Typical analysis
- Nitrogen: 0%
- Phosphorus: 0%
- Potassium: 0.5%
- Seaweed solids: 3 to 4% w/v
- Organic matter: 2.5%
- Typical pH: 4.2
How to use Ecothrive Flourish as a root feed
Apply at 0.25 to 0.5ml per litre of water. It can be used with every watering on its own or alongside compatible nutrients and additives. Ecothrive recommends stopping root applications approximately one to two weeks before harvest.
How to use Ecothrive Flourish as a foliar spray
For foliar application, use 10ml per litre of water every 10 to 14 days. Apply during suitable growth stages and stop spraying flowering plants once flowers have started to form.
Using Flourish in hydroponic systems
The refined and filtered formulation is designed to remain soluble and stable in hydroponic nutrient reservoirs, making Flourish suitable where thick organic extracts or suspended solids would be undesirable.
Flourish is not a base nutrient
With an NPK analysis of approximately 0-0-0.5, Flourish cannot provide complete mineral nutrition on its own. Continue using the appropriate base nutrient or living-soil feeding programme and use Flourish as a supplementary biostimulant.
Flourish vs Ecothrive Charge
- Ecothrive Flourish: a liquid seaweed biostimulant used through irrigation water or as a foliar spray.
- Ecothrive Charge: a mealworm-frass solid amendment mixed into the growing medium or used as a top dress.
Available sizes
- 250ml: practical for smaller gardens or occasional use.
- 1 litre: suitable for regular use.
- 5 litres: suited to larger growing areas and regular irrigation programmes.
The NPK Gardening Solutions take
Flourish is useful because it gives growers the benefits of a seaweed extract without asking them to put a thick organic liquid into a hydroponic reservoir. We would use it as a low-dose biostimulant alongside a properly managed feeding programme, not as a replacement for nutrition.
Choose Ecothrive Flourish if you want a clean, concentrated seaweed biostimulant that can be used through the root zone or as a foliar spray.
