Mills Nutrients is a Dutch nutrient range built around one two-part base, Basis A&B, plus four stage-specific additives: Start-R for roots and early growth, C4 for early to mid bloom, Ultimate PK for late flower, and Vitalize, a concentrated mono-silicic acid added to every feed. Designed, made and bottled in Holland, and run in hydro, coco and soil.
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.
