pH Test Indicator (Liquid Drop Test, 1 oz) from Aquager Technologies is the simple, reliable way to monitor pH in your hydroponic farm or soil garden — just 4 drops in the included test vial reveals exactly where your nutrient solution sits on the pH scale.

  • Easy color-matching: Compare the test sample to the included pH chart for instant readings.
  • No batteries, no calibration: Liquid test never fails — unlike electronic pH meters.
  • Hundreds of tests per bottle: 1 oz lasts months of regular weekly testing.
  • Test vial included: Everything you need in the box — start testing in seconds.

Optimal hydroponic pH is 5.5-6.5 — and you can't hit that target without testing. Order from Aquager Technologies today and take the guesswork out of feeding your plants.

Straight From Growers

The Fox Farm nutrients made a noticeable difference within a week — my basil went from pale to lush and fragrant almost immediately.

— Isabelle F., New Orleans, LA

Solid nutrient formula. Plants are noticeably greener and growing faster. Would love a slightly bigger bottle for the price.

— Jay M., Portland, OR

Finally a hydroponic nutrient that actually works for beginners. No complicated mixing ratios — just add 20ml and you're done.

— Priya K., Chicago, IL

The germination nursery is a game-changer. Every seed I've started in it has sprouted, and the humidity dome keeps everything perfectly moist.

— Carla H., Denver, CO

Love that the nursery is reusable. Compact enough for my kitchen counter and the adjustable vents gave me way more control than I expected.

— Miguel R., Miami, FL

The 10x20 grow trays are sturdy and fit my setup perfectly. Wish they came with more mats included, but quality is solid.

— Ethan L., Seattle, WA

Great tray set. Three trays is the perfect starter amount and the mats make the whole process so much cleaner.

— Yolanda B., Atlanta, GA

The air pump runs quietly and keeps the water oxygenated around the clock. My plants' roots look healthier than ever.

— Tom S., Nashville, TN

Accessories are well-made and match the farm's design aesthetic. Happy everything ships fast too.

pH kit works great. Readings are accurate and it gave me peace of mind knowing my water levels were in the right range.
