Need to bulk up your plants before bloom? Grow Fast by Professors Nutrients is your secret weapon for a monster veg phase. This high-performance liquid booster slams your plants with fast-acting Nitrogen in multiple forms for explosive growth, bigger leaf canopies, and a sturdy structure.

No stretchy, weak stems here - just controlled, balanced growth and quicker turnarounds. Ideal for hydro and coco heads chasing shorter cycles and bigger harvests.

🔹 Key Features

🌿 Nitrogen triple threat — Rapid-uptake forms for max absorption

🍄 Shortens veg phase — Accelerates development without the stretch

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.
