Advanced Nutrients Big Bud Coco — Coco-Optimised Flowering Booster
Takes the classic Big Bud formula and optimises it specifically for coco coir growing — contains a wide spectrum of yield-boosting and flavour-enhancing ingredients, with particular attention to iron supplementation. Coco coir, like other media, has a tendency to bind iron (alongside calcium), leading to deficiencies; many bloom boosters neglect this, but Big Bud Coco addresses it directly.
Why growers choose Big Bud Coco:
Coco-specific reformulation — accounts for coco's unique binding chemistry
Iron supplementation included — addresses the #1 coco deficiency that plain Big Bud doesn't
Wide yield-boosting ingredient spectrum — not just NPK, broader support for flower development
Mid-to-late flower usage — peak effect during weeks 3-6 of bloom
Integrates with AN coco programme — Sensi Coco Grow/Bloom, Voodoo Juice, etc.
Addresses coco-specific deficiencies — better than using Big Bud (non-coco) in coco
Who it's not for:
Specifically for coco growing — for hydroponic or soil, use standard Advanced Nutrients Big Bud. For budget-conscious flowering, Buddha's Tree PK 9-18 is cheaper but doesn't have the iron/Ca emphasis. Stop 7-10 days before harvest. Works best integrated with the full Advanced Nutrients coco schedule rather than as standalone. For serious commercial-scale coco, 4L or larger bottles are better value than smaller sizes.
