Clay Pebbles from Aquager Technologies are lightweight, porous expanded clay balls, the reusable grow medium at the heart of every Aquager Home Farm setup. Rinse, reuse, and never buy a fresh grow medium again.

  • Fully reusable: Rinse clean between grows and reuse indefinitely, no replacing spent grow medium.
  • Excellent drainage and aeration: Porous structure lets roots breathe while wicking moisture up from below.
  • pH neutral and inert (pH 6.5–7.5): Won't affect your nutrient solution's chemistry.
  • Lightweight and easy to handle: Simple to fill, rinse, and store between cycles.

How to use it: Fill each grow cup about five-sixths full with clay pebbles, then set a grow square on top before adding seeds. The pebbles anchor the square and wick water up from the reservoir, keeping seeds and roots consistently moist without waterlogging them.

One bag is enough clay pebbles for a full 24-cup Aquager Home Farm. Order from Aquager Technologies today and get your farm growing.

  • Bag size: Approximately 360g (about 13 oz / 0.8 lb), enough for a full 24-cup Aquager Home Farm
  • pH: 6.5–7.5 (neutral, won't affect your nutrient solution)
  • Reusable: Rinse and reuse across countless grow cycles
  • Works with: Loose seeds and grow squares, or your own seedlings
  • Pairs well with: Tiny Grow Squares if you're supplying your own seeds.

As the pebbles gently shift and rub against each other, they can release a small amount of natural dust over time. This may settle as light sediment at the bottom of your reservoir, so it's a good idea to check and rinse your tank periodically, and keep an eye on your water pump and other mechanical parts to keep everything running smoothly.

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.

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

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

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.
