Advanced Nutrients
pH Perfect, since 1999.
The reason a lot of growers stopped testing pH daily: the base feeds pull the reservoir into range and hold it there.
Nothing matches all of those filters.
Base feeds
The staple. Everything else goes on top of this.
Flowering boosters
Used through the second half of the cycle.
Vegetative boosters
For the growth period, before flowering starts.
Root stimulants
For young plants, cuttings and after transplanting.
Flavour and aroma
Precursors for essential oils and pigments.
Cal-Mag and pH control
Correcting the water before the feed goes in.
Enzymes and additives
Everything that is not a base feed or a booster.
Accessories and spares
Replacements and fittings, kept out of the way of the main range.
Advanced Nutrients — pH Perfect base feeds
Advanced Nutrients built its base feeds around pH Perfect technology, which self-adjusts and holds pH within the ideal range for around four weeks after mixing, so you're not chasing a pH pen every time you top up a reservoir. The range on the shelf here focuses on the booster side: Big Bud for soil and hydro, Big Bud Coco formulated separately for coco growers, Bud Candy for carbohydrates and terpene support, CarboLoad for feeding beneficial microbes, and Overdrive as a late-flower PK finisher.
Because Big Bud and Big Bud Coco are chemically different formulas rather than the same product in two bottles, check which one matches your medium before buying — using the soil/hydro version in coco can throw your cal-mag balance off. These boosters are designed to stack: a typical late-flower schedule runs Big Bud, Bud Candy and Overdrive together from around week 4 through to the final plain-water week.
Pair with a base feed from any brand — Advanced Nutrients boosters aren't tied to their own base — and see flowering boosters for the wider PK range if you want to compare against other brands. Free UK delivery over £60 and free Wembley pickup.
