Bloom Yellow Bottles - Groigen

Bloom Yellow Bottles Groigen is a concentrated foliar growth spray designed to encourage vigorous vegetative development, healthy foliage and stronger branch growth. Part of the Bloom Advanced Floriculture range, Groigen delivers plant-supporting nutrients and compounds directly to the leaves, providing an additional feeding method alongside conventional root-zone nutrition.

Formulated with natural plant extracts, minerals, vitamins and amino acids, Bloom Groigen supports leaf development and the growth of healthy, productive plants. Its foliar application method is particularly useful during the cloning and vegetative stages, when growers want to establish a strong canopy and encourage consistent growth.

Suitable for plants cultivated in hydroponics, coco coir and soil, Groigen can be used in indoor grow tents, grow rooms, greenhouses and outdoor gardens. The manufacturer recommends applying the diluted spray while grow lights are switched off to reduce the risk of leaf damage.

Who It’s For

Bloom Yellow Bottles Groigen is ideal for growers looking for a dedicated vegetative foliar feed to support healthy leaf growth, stronger branching and vigorous plant establishment. It is particularly useful for growers propagating clones and young plants or developing a healthy canopy before flowering.

Groigen is suitable for hydroponic growers, coco cultivators and soil gardeners who want to supplement conventional root feeding with a foliar application. It can be incorporated into growing programmes for indoor grow tents, grow rooms, greenhouses and outdoor gardens.

The product is also suitable for customers using the Bloom Advanced Floriculture nutrient system who want an additional vegetative-stage spray without replacing their regular base fertilisers. Growers seeking a foliar product specifically for flowering should use a product intended for that growth stage instead.

How To Use

Application Timing: Use Bloom Yellow Bottles Groigen during the cloning and vegetative growth stages. The manufacturer recommends foliar application throughout vegetative growth, with use discontinued when plants enter the flowering stage.

Dilution: Mix 20ml of Groigen per litre of water. For example, a 300ml bottle makes 15 litres of prepared foliar spray at the recommended concentration.

Preparation: Fill a suitable foliar sprayer with the required amount of water. Measure the appropriate quantity of Groigen, add it to the sprayer and mix thoroughly before use.

Application: Spray the plant foliage thoroughly to distribute the diluted solution across the canopy. Apply when grow lights are switched off, following the manufacturer's guidance to reduce the risk of leaf damage from spraying under intense lighting.

Clones and Young Plants: Groigen can be used as a supplementary foliar feed for clones during establishment. Apply according to the manufacturer's dilution guidance and avoid unnecessary overapplication.

Existing Nutrient Programme: Continue using your regular base nutrients according to the relevant feeding schedule. Within the Bloom Advanced Floriculture system, Groigen is designed to provide supplementary foliar nutrition rather than replace root feeding.

Transition to Flowering: Discontinue Groigen when the vegetative phase ends. If following the Bloom Yellow Bottles programme, use the appropriate flowering-stage products and feeding schedule for subsequent growth.

Storage and Handling: Keep the container securely closed and follow the storage instructions on the product label. As the formulation contains naturally sourced ingredients, some variation in colour and consistency may occur between batches. Prepare the spray at the recommended concentration and follow the manufacturer's application instructions.
