Expanded Clay or LECA (lightweight expanded clay aggregate) is an excellent growing medium which can be used in aquaponic farming, hydroponic growing systems, and conventional soil-based agriculture too.
Best used in our Hydropot series, but also a suitable medium for use in flood and drain or nutrient film technique hydroponic systems.
Note: Requires an initial wash to rinse clean. Soak for a few hours and stir around before draining.

This is the first time I’m using this type of product and so far I’ve been happy with the results. The plants are surviving.
Honestly I was a bit skeptical this product, but I really loved it using it with hydro plants and a plant topper to prevent pests does the trick. Would 100% reccommend.
Seem to be helping my orchids and air plants - they are all flowering! The also look great in pots
Still very new with this medium, so far having fun experimenting it as a toper, at the bottom of soils and for hydroponic plants . Will definitely purchase when running low
Quick delivery and quality product. Would recommend.
I haven't used leca before but I am happy with the results
So good to hear, Aimee! From the Urban Plant Growers Team.
Quick delivery and easy to use. Converting all my plants slowly and this is so good!
If you’re in the market for expanding clay balls, these are the balls for you!
First time trying leca. Was great quality and good amount too
Great product. I am changing over to the Leca for my indoor plants in self watering pots. It is much cleaner than potting mix. So far my plants seem to be adjusting well.
It s good quality and easy to use.
Good I like the product. I have been order twice already
