Boom Nutrients expanded clay pebbles are useful to drain water from the soil. They can be used as a substrate when growing hydroponically in mesh flowerpots.
Description
Expanded Clay to Improve the Substrate
Clay Pebbles are used in various different types of grows, especially when it comes to growing cannabis.
Improve substrate drainage
It can be used at the bottom of your flower pots to help drain out more water from your plants’ substrate, making sure that the water doesn’t pool at the bottom of the pot which can cause some real issues with your plants’ roots. You can also place some clay pebbles at the bottom of your cutting Propagator + Tray Kit to reduce humidity.
Hydroponic Substrate
They can also be used in hydroponics, filling your mesh puts with clay pebbles and planting your seeds or cuttings in rockwool cubes. You can reuse clay pebbles as much as you want as long as you clean them of any residues. If you’re growing with new clay you will need to balance its pH to 5.5 overnight before planting – it’s an annoying process, although once done you won’t ever have to do it again.
How to Prepare Clay for Growing
Wash them through with clean tap water and a large sieve until the water begins running through completely clean – if you don’t do this, your water tank could become blocked up with dirt. Now, prepare a container with osmosis water adjusted to a 5.5 pH (it’ll need a 0.0 EC) and let the clay sit there for 24-48h.
You’ll probably need to lower the pH a few times until it’s at 5.5 – they’ll fight to go back up to 7 pH. Once you have them down to 5.5 you can start growing using clay pebbles!
Discreet shipping.

I use it to improve drainage and root aeration both at the bottom of the pots and on top of the substrate. At the base, it helps prevent waterlogging and improves root oxygenation; on top, it reduces evaporation and prevents fungi and pests. Highly recommended
Translated from Spanish
La utilizo para mejorar el drenaje y la aireación de las raíces tanto en el fondo de las macetas como en la parte superior del sustrato. En la base, ayuda a evitar encharcamientos y mejora la oxigenación radicular; en la parte superior, reduce la evaporación y previene la aparición de hongos y plagas. Muy recomendable

Can it be stabilized directly with distilled water since it comes at a pH of 5.8, would that work?
Translated from Spanish
Se puede estabilizar con agua destilada directamente ya que viene con un 5.8 de pH serviría ?
