🌿 One Bottle to Rule Them All

Why faff about with two bottles when one does the job beautifully? Professor's Original Nutrient is your no-fuss, Aussie-made all-in-one Grow + Bloom formula that’ll take your plants from zero to hero with no mid-cycle switcheroos.

🔹 Key Features

🔥 All-in-one Grow + Bloom blend – no more juggling bottles

🧪 Chelated minerals for fast uptake and lush growth

📏 Works across hydro, coco, soil, and more

🛠️ How to Use It

Hydroponics: Add equal parts A & B to your reservoir based on EC targets. Adjust pH to 5.5–6.4. Change weekly for best results.

Soil or Coco: Use at half strength for outdoors, quarter strength for seedlings. For a leafy pick-me-up, foliar feed with 2ml A + 2ml B per litre.

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.
