Product Overview
Bud Booster 0-1-3 is a concentrated phosphorus and potassium supplement that increases flower density, boosts resin production, and maximizes yields during critical flowering stages. The nitrogen-free formula delivers targeted bloom nutrition without promoting unwanted vegetative growth during reproduction.
Base nutrients provide adequate PK for average flowering, but growers targeting maximum yields need elevated phosphorus and potassium during peak bloom. Bud Booster supplements base feeding with the extra PK that drives heavier, denser flowers with increased terpene and resin concentrations.
Key Benefits
- Concentrated PK formula increases flower weight and density
- Zero nitrogen prevents leafy growth that diverts resources from flowers
- Potassium supports terpene synthesis and aromatic compound production
- Phosphorus powers energy-intensive flower development and maturation
Ideal For
Growers wanting to push flower production beyond what base nutrients deliver alone. Use alongside your regular feeding program—Bud Booster supplements rather than replaces base nutrients.

Frequently Asked Questions
When should I start using Bud Booster?
Begin using Bud Booster at the start of the flowering phase. For photosensitive plants, that’s typically Week 5 on our feed charts. For autoflowers, start using it once pistils form and you’ve transitioned to Clyde + CalMag.
How often do I apply Bud Booster?
Use it once per week during the flowering stage. In coco or hydro systems, many growers run it every feed at the charted rate.
Can I use Bud Booster with any base nutrients?
Yes! Bud Booster is fully compatible with:
• Classic Line: Grow, Micro, Bloom
• Autoflower Line: Bonnie & Clyde (used only during bloom with Clyde)
• PuurOrganics: 100% compatible — works great as an additional PK bloom push
It blends clean in soil, coco, and hydro.
• Classic Line: Grow, Micro, Bloom
• Autoflower Line: Bonnie & Clyde (used only during bloom with Clyde)
• PuurOrganics: 100% compatible — works great as an additional PK bloom push
It blends clean in soil, coco, and hydro.
Does Bud Booster replace Bloom nutrients?
No — Bud Booster supplements your bloom nutrients. Keep running your normal Bloom (Classic Line), Clyde (Autoflower Line), or PuurPhos/PuurK (PuurOrganics).
Will Bud Booster burn my plants?
Bud Booster has a gentle 0-1-3 formula, so it’s very forgiving. As long as you follow your feed chart and mix properly, it’s extremely unlikely to cause burn.
Can I use Bud Booster in organic grows?
Yes! While Bud Booster itself isn’t organic, it’s fully compatible with the PuurOrganics system and won’t harm microbial life or Monkey Juice bacteria.
