Pairs well with

The pH of a nutrient solution is critically important. Plants absorb minerals best between pH 5.5 and pH 6.5

Growth Technology pH Down is 85% phosphoric acid and needs to be handled with care. If you get it on yourself or your clothes, wash it off immediately.

pH adjustment should be the done last after nutrients and additives have been added to the tank. Recirculating systems may need the addition of pH Down every day since the pH of the nutrient solution tends to rise over time.

Health and Safety

  • always wear gloves and eye protection
  • store in a locked cupboard
  • keep away from children
  • dilute with water before adding to the tank. Add acid to water, not the other way around.
  • safety data sheets are available.

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.
