40 products

Showing 1 - 36 of 40 products

Keep your garden thriving with Dr Greenthumbs’ Water Testing range, selected for precision and rugged reliability by Australian organic and hydroponic growers. Whether you’re choosing an ec meter or a handheld ph meter, our pocket-size tools, waterproof ph pens, and fresh ph buffers deliver lab-grade readings for crystal-clear nutrient control.

Regular checks stop nutrient burn at high readings and deficiency at low ones, securing faster growth and bigger yields. Need a corrective fix? Pair your new meter with our pH adjusters and buffers for rapid, stable shifts, or browse the wider EC & pH Meters line for pro-grade options. All orders ship fast from our Wollongong base with down-to-earth advice if you get stuck.
