🌿 Bio Diesel Rhino K – Organic Potassium Bloom Booster

Boost your buds naturally with Rhino K, a powerful organic bloom enhancer designed for soil, coco, and hydroponic grows. Unlike other PK bloom boosters, Rhino K contains no harsh phosphates, making it microbe-friendly and safe for your soil’s beneficial life. 🐛🌱

This pure 15% organic Potassium (K-Citrate) formula helps deliver bigger, denser flowers by increasing bud burst at flower onset and hardening calyxes during the last critical weeks of bloom. Expect fuller, more resinous buds packed with intense terpenes and trichomes—perfect for growers chasing top-shelf quality. 🌸✨

With fulvates and essential vitamins included, Rhino K maximises nutrient movement and reproductive energy, directing your plant’s reserves towards flower production and oil development.

  • 🌼 Promotes more flowering sites and heavier blooms

  • 💎 Boosts trichome and terpene production for potent aromas & effects

  • 💪 Hardens calyxes for bigger, denser flowers

  • 🎨 Enhances colour expression at harvest

  • 🌿 Suitable for organic growing in soil, coco, and hydroponics

  • 🌱 Flushes cleanly with no harsh residues


How to Use Rhino K:

Flower Onset (First 2 weeks of bloom):

  • Add 1–2ml/L to your watering solution and apply to roots

  • Or foliar spray at 1ml/L twice a week (only before flowers form)

Flower Hardener & Resin Booster (Last 3 weeks of bloom):

  • Water in at 1–2ml/L depending on plant size

  • Apply consistently during weeks 5–8 of a 9-week flowering cycle

  • For hydro growers, add to reservoir 48 hours before tank change for best results

Tip: Use Rhino K within 48 hours of diluting in water for maximum effectiveness.


📦 Available Sizes: 250ml / 1L / 5L

Growers First, Retailers Second

Welcome to The Grow Guys

We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
