Description
Advanced Nutrients Big Bud Coco takes the classic Big Bud bloom booster formula and optimises it for growing in coco coir. It is enriched with a wide spectrum of yield boosting and flavour enhancing ingredients, including extra iron, since coco coir tends to hold onto iron and calcium, which can lead to deficiencies if a feed is not adjusted for it.

How Big Bud Coco Works
Big Bud is one of the most widely used bloom boosters among coco and hydro growers. Big Bud Coco takes that same formula and tweaks the mineral balance specifically for coco coir, correcting for the iron and calcium lock up that coco media is prone to. The result is stronger, more even flower development and a heavier finished harvest.
How to Use Big Bud Coco
- Start from week 2 of flowering and continue until around three weeks before harvest
- Mix thoroughly into your base bloom feed, following the dosage on the bottle for your reservoir size
- Add Big Bud Coco after your base nutrients and any other additives; never mix concentrates undiluted
- Check pH and EC after mixing, as with any coco coir feeding programme
Which Size to Choose
Big Bud Coco is stocked in three sizes to suit different grow scales.
| Size | Suits |
|---|---|
| 1L | A single flowering cycle in a small to mid size coco tent |
| 5L | Repeat growers running several coco cycles a year |
| 10L | Larger coco rooms or multiple tents on the same feeding schedule |
Big Bud Coco FAQs
Is Big Bud Coco different from the standard Big Bud?
Yes. Big Bud Coco uses the same base formula as Advanced Nutrients Big Bud, but with extra iron and a mineral balance corrected for coco coir, where iron and calcium are more easily locked up.
Can I use Big Bud Coco in soil or hydro instead of coco?
Big Bud Coco is formulated specifically for coco coir. Growers in soil or run to waste hydro systems are better suited to the standard Big Bud.
When should I start and stop using Big Bud Coco?
Start from week 2 of flowering and use until around three weeks before harvest, then many coco growers switch to a finishing booster to help ripen the crop.
Will Big Bud Coco cause nutrient lockout in coco?
Used at the correct dose alongside a coco-suited base feed, Big Bud Coco is designed to reduce lockout risk rather than cause it. Always check pH and EC after mixing.
Can Big Bud Coco be overused?
Yes. Overuse can cause nutrient imbalance or salt build up, so stick to the recommended dose and keep an eye on EC and pH.
