Product Details

🪴 Mills Nutrients Ultimate PK – Heavyweight Bloom Booster

Ready to take your flowering phase to the next level? 🌸 Mills Ultimate PK is your go-to bloom booster, delivering dense, weighty flowers and next-level aromas in the final weeks of flowering. Perfect for the last 2–4 weeks of bloom, it pushes your plants to peak performance.

📌 Why Growers Love Ultimate PK:

💥 Explosive flower production – bigger, harder, denser flower buds
🔥 Higher terpene levels – boost aroma, flavour & bag appeal
⚖️ Increased yields & final weight – get the most from every grow
🌱 Universal use – works with coco, hydroponics, and soil
🧪 Powerful PK formula – ideal for the ripening stage of flowering
⏱️ Adaptable timing – follow the Mills chart or add a week earlier for fast-flowering varieties

👀 Pro tip: If your plants are finishing faster than expected, A-Grade Hydroponics recommends using Ultimate PK one week earlier than the standard Mills Pays The Bills feed chart suggests.

🗣️ Customer favourite: Growers rave about the results—this bloom booster has become a staple in hydroponic gardens across Australia. Don’t just take our word for it... try it and see the rock-hard difference! 💪
