🌱 Perfect pH? Too Easy!

If your pH is outta whack, your plants won’t be happy. Luckily, Growth Technology pH Up and pH Down are here to bring balance back to your grow. Whether things are swinging too acidic or too alkaline, this dynamic duo keeps your nutrient solution in the sweet spot for epic growth.

🔹 Key Features

🔥 Fast-Acting Formula – Instantly adjusts pH in hydro, soil, or coco setups.

🧪 High-Concentration Goodness – pH Down is 85% phosphoric acid, pH Up is 25% potassium hydroxide. Potent stuff.

🔹 Stops Nutrient Lockout – Keeps uptake humming and deficiencies in check.

🛠️ How to Use It

  1. Mix your nutrients first.

  2. Dilute the pH Up or Down in water – about 1mL per litre is your starting point.

  3. Add slowly, stir well, and always retest. A little goes a long way!

  4. If you're running a recirculating system, check daily – drift happens.

Safety First, Legends: Gloves and goggles are a must. And remember: add acid to water, never water to acid.

🌿 Grow Guys Tips

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.
