PRODUCT INFORMATION
PRODUCT INFORMATION

Made from expanded clay, Canna Aqua Pebbles are porous, lightweight and make for a fantastic all round hydroponic medium for systems such as the Alien and IWS. They are also great for mixing with your soil and coco to create a far more aerated medium which drains more freely. This not only helps reduce the chance of overwatering but also allows your plant the possibility to receive more nutrition due to the increased amount of irrigations you can now provide it. They are chemically inert as well as pH stable meaning they will not interfere with any other mediums or the nutrients you are feeding.

The size of our clay pebbles in the bag vary between 8-16mm and are all a uniform, circular shape with a smooth surface. This is especially good for when they are used as the standalone medium as there is no chance of damage to the root zone which can occur with other brands that have a more ‘jagged’ shape.

Canna Aqua Pebbles are pre-washed but we always highly recommend washing them before use to ensure that any extra dust is removed. This is especially important where pebbles are being used as the only choice of medium in a hydroponic system as you do not want to risk any pipe blockages! If using pebbles as a standalone medium then always use a ‘hydroponic-specific’ nutrient.

Pebbles can also be used in the top and bottom of your pots! Add a layer of pebbles to the top of each of your pots as a ‘mulch’ layer to help keep your growing medium moist. Alternatively adding a layer at the bottom of your pot can help aid drainage and is particularly important for when you a bottom feeding your plants or using an AutoPot System as it will practically eliminate the risk over overwatering.

Clay Pebbles can also be reused! Once you have harvested your crop and removed the bulk of it, soak them with a heavy dose of an enzyme product such as Cannazym to break down the remaining roots and dead plant matter. Then before re-planting wash them out with a solution of Liquid Oxygen to ensure they are sterile and clean.

Expanded Clay Pellets

I’ve just received the pellets last week and today we rinsed them as per the instructions. They are now being stored in a bucket of water for 24 hours as recommended and then I will be planting up strawberry plants for next year in my Gardena NatureUp. Looking forward to great strawberries next summer. Next year I would have more idea how the clay pellets will perform but I can see the benefits.

Washing ****!

First off, I'd like to express my gratitude to GroWorks for their prompt dispatch considering the current situation we all find ourselves in. This was first experience with clay pebbles. I had read how important it was to wash them and then wash them again. I would like to qualify that with .... again and again and again! If anyone comes up with a pre-washed version, I'd be in like a shot! As I'm unable to compare this particular brand with any other I can't really express an objective opinion as far as quality is concerned. Having said that, they are in their pots doing their thing and all seems well. I would have no problem buying them again when needed (unless a pre-washed version catches my eye)!
