The GreenPlanet Bud Booster is GreenPlanet's original powdered bloom additive, delivering high phosphorus and potassium with added boron and nitrogen. It's an easy, economical first step for growers adding a flowering booster to their program, and it comes in sizes from a 60 g trial pack to 5 kg.
What it adds
Phosphorus supports flower formation, potassium supports flower quality and sugar production, and the added boron helps plants move sugars to developing flowers. A small amount of nitrogen keeps basic plant functions running while the booster does its job.
How to use it
Use 6 g per 20 litres (1 teaspoon per 5 US gallons) once buds are forming, and continue with every feed through bloom. Stop in the final week of flower.

FAQ
Bud Booster or PK Spike?
Both add P and K in flower. Bud Booster is a powder with added boron and nitrogen; PK Spike is a liquid. Use one, not both.
Is it good for a first grow?
Yes — it's simple to dose and the 60 g size lets you try it without committing to a large pack.
Can I mix it with another brand?
We don't recommend it. GreenPlanet's feed programs are built around its own bases and additives, so results are most predictable when you stay within the range.
