Evoponic Bud Monster 500g (0-50-30) - High-PK Flowering Booster
Best for: growers wanting an extra push of phosphorus and potassium through the middle stages of flower.
Our thoughts
This is a straightforward PK booster, high phosphorus and potassium, aimed at the stretch and bulking phase of flower when plants are putting real energy into bud development. Nothing flashy about it, just the two nutrients that matter most at that stage, in a strong ratio.
Evoponic Bud Monster is a mineral flowering booster with an NPK ratio of 0-50-30, meaning it's built almost entirely around phosphorus and potassium rather than nitrogen. It's designed to be added during the middle stages of flower development, when plants shift their energy from vegetative growth into bud formation, to support the plant's natural flowering response and encourage denser, better-developed fruit or flower.
It comes as a 500g powder, added alongside your existing base nutrient programme rather than as a standalone feed.
How it compares
High-PK boosters are a well-established category in flowering nutrition, with a few household names.
- Like Canna PK 13/14, it's a concentrated phosphorus-potassium booster designed to be added on top of a base feed during the flowering stretch.
- Compared to Advanced Nutrients Big Bud, which combines PK with other bloom-support ingredients, Bud Monster is a more focused, straight NPK product.
- Against Hammerhead, another phosphorus-heavy booster, Bud Monster's 0-50-30 ratio leans further into potassium as well as phosphorus.
It's a no-frills PK boost rather than a multi-ingredient bloom formula, which keeps it simple to dose alongside whatever base nutrients you're already running.
Usage guidance
PK boosters are easy to overdo, so stick to the dosing on the pack rather than guessing.
When to start
Introduce Bud Monster during the middle stages of flower, once your plants have moved past the initial stretch and are actively building bud structure.
Dosing
Follow the feed chart on the packaging for your reservoir or watering can size, and adjust based on your EC readings rather than adding on top of an already-full feed.
Combining with base nutrients
Add alongside your existing base feed rather than in place of it, Bud Monster is a booster, not a complete nutrient.

Our take
Bud Monster does one job, giving your plants a strong phosphorus and potassium boost during flower, and does it without unnecessary extras. It's a sensible pick-up for anyone already happy with their base nutrients but wanting more from the flowering stage.
Worth picking up if you want a simple, effective PK boost without paying for ingredients you don't need.
