Bloom Yellow Bottles - Seafuel

Bloom Yellow Bottles Seafuel is a concentrated organic-based flowering tonic and plant biostimulant designed to support healthy plant growth, nutrient uptake and root-zone activity during the flowering stage. Part of the Bloom Advanced Floriculture nutrient range, SEAFUEL combines marine-derived ingredients, including cold-composted tuna and kelp, with fulvic acid to provide a broad spectrum of nutrients and naturally occurring plant-supporting compounds.

Developed to complement regular hydroponic nutrients, Bloom SEAFUEL supplies beneficial microorganisms, amino acids, vitamins and trace minerals that help maintain a healthy growing environment. The cold-composted fish ingredients contribute nutrients and microbial activity, while kelp provides naturally occurring plant compounds associated with growth and stress tolerance. Fulvic acid supports nutrient availability and uptake, helping plants make effective use of their existing feeding programme.

Suitable for hydroponics, coco coir and soil cultivation, Bloom Yellow Bottles Seafuel is particularly useful during flowering, when plants require consistent nutrition and a healthy root zone. Its concentrated formula makes it a practical addition to feeding programmes in grow tents, indoor grow rooms, greenhouses and outdoor gardens.

Who It’s For

Bloom Yellow Bottles Seafuel is ideal for growers seeking an organic-based plant tonic to support flowering performance, nutrient uptake and overall plant health. It is particularly suitable for hydroponic growers, coco cultivators and soil gardeners who want to supplement their regular feeding programme with marine-derived nutrients and plant-supporting compounds.

Growers cultivating in indoor grow tents, dedicated grow rooms, greenhouses or outdoor gardens can incorporate SEAFUEL into their flowering schedule to support root-zone activity and plant resilience. It is also useful for growers managing plants affected by environmental stress or looking to maintain a healthy microbial environment around the roots.

Bloom SEAFUEL is especially relevant to customers following the Bloom Advanced Floriculture nutrient programme, where Bloom Seaweed is used primarily during vegetative growth and Bloom Seafuel is introduced during the flowering phase.

How To Use

Application Timing: Add Bloom Yellow Bottles Seafuel to your regular feeding programme during the flowering stage. Under the UK manufacturer's feeding guidance, discontinue use when entering the final flush, typically during the last 1–2 weeks before harvest. Follow the current feeding schedule appropriate to your growing method.

Dosage: The general recommended application rate is 1ml per litre of water or nutrient solution. More specific rates vary depending on the irrigation system:

• Recirculating hydroponics: 0.5ml per litre.
• Soil cultivation: 0.5ml per litre.
• Run-to-waste systems: 1ml per litre.

Mixing: Prepare your normal base nutrient solution according to the relevant feeding schedule. Measure the required amount of Bloom SEAFUEL, add it to the water or nutrient solution and mix thoroughly before application.

Feeding: Apply the prepared solution through your normal watering or irrigation system. Monitor the final pH and EC where appropriate for your growing medium. Within the Bloom Advanced Floriculture feeding programme, SEAFUEL is designed to complement the regular base nutrient application rather than replace it.

Transition Between Growth Stages: For growers following the Bloom Yellow Bottles programme, use Bloom Seaweed during vegetative growth and transition to Bloom Seafuel for flowering, following the relevant feed chart.

Storage and Maintenance: Keep the container securely closed and store it according to the product label. As SEAFUEL contains naturally derived marine ingredients, variations in colour and consistency can occur between batches. Follow the manufacturer's feeding guidance and avoid exceeding the recommended dosage.
