pH Down Solution (8 oz pH Adjuster) from Aquager Technologies safely lowers the pH of alkaline water back into the optimal 5.5-6.5 hydroponic range — essential for hard tap water and post-flowering nutrient adjustments.

  • Concentrated formula: Just a few drops per gallon — one 8 oz bottle treats hundreds of gallons.
  • Fast-acting correction: Quickly drops alkaline water to the optimal range for nutrient uptake.
  • Plant-safe: Gentle formula won't harm roots or foliage when properly dosed.
  • Essential for hard water: Most municipal tap water runs alkaline — pH Down brings it home.
  • Long shelf life: Stable formula stays effective for years when stored properly.
  • Pairs with pH Test Indicator: Test, then dose with precision using a dropper.
  • Works for any water source: Hydroponic reservoirs, soil drench, foliar mixes.

Alkaline water locks out iron, manganese, and other key nutrients — a common cause of yellow leaves. Order from Aquager Technologies today and dial in the optimal pH.

Compatible with Aquager Hydroponic Home Farm AND any soil garden — for indoor or outdoor use!

  • Size: 8 oz / 237 ml concentrate
  • Use when: pH reading rises above 6.5
  • Optimal pH for hydroponics: 5.5 - 6.5

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.
