Hydroponic Nutrients
Hydroponic nutrients for every grow — base A&B formulas, bloom boosters and additives from Green Planet, CANNA and other proven brands. Stocked in Australia and matched to your system by growers with 14 years behind the counter.
Hydroponic Nutrients for Every System and Stage
Base Nutrients Matched to Your Medium
Coco, recirculating, run-to-waste or soil — every base nutrient here is sorted by the system it's built for, so you're buying the right A&B first time, not fixing deficiencies later.
Additives That Earn Their Spot in the Reservoir
Our best sellers are best sellers for a reason: Rezin for aroma and resin, Root Builder for the root zone, Massive Bloom for flower weight. If it doesn't move the result, we don't stock it.
Hydroponic Nutrients Backed by 14 Years of Growing
Everything in this range is run in real Australian grows before it hits the shelf. Not sure what your setup needs? Ask — recommendations come from growers, not a script.

FAQs
What hydroponic nutrients do I need to get started?
Start with an A&B base nutrient matched to your medium, plus pH up and down to keep your solution in range. Our beginner nutrient kits bundle a full start-to-finish feed in one box.
Are hydroponic nutrients different for coco, soil and recirculating systems?
Yes. Coco formulas are buffered for calcium and magnesium demand, recirculating formulas stay stable in a reservoir, and soil formulas feed the biology as well as the plant. Match the base to the system.
Do you ship hydroponic nutrients Australia-wide?
Yes, every nutrient in this range ships Australia-wide in discreet packaging, with free shipping over $499*.
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.
