🌿 Flush the Junk, Boost the Funk

Got salt build-up and tired terps? Time to clean house. Ultra Flush by Professor’s Nutrients is the grower’s secret weapon for cleansing your substrate. It flushes excess salts, fixes nutrient lockout, and primes your plants for a smoother, tastier finish.

🔹 Key Features

🔥 Flushes excess salts fast – Clears the root zone and growing medium for clean nutrient uptake.

🧪 Unlocks flavour & aroma – Boosts terpenes and essential oils before harvest.

🕰️ Final flower swell support – Encourages a dense, frosty finish in the last stretch.

🛠️ How to Use It

Hydro Growers:

Week 1 & 4 of flower: Mix 3ml/L in your res. Run for one day, then dump.
Final week before chop: 3ml/L daily for cleaner, terp-rich colas.

Fixing Nutrient Lockout?

Mix 30ml in 10L water.
Pour directly over the growing medium.
Wait 48 hours.
Resume feeding at half strength, then full after a week.

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.
