Hello everyone!
Someone has used this HydroGel in their cultivation:
Stockosorb or HydroGel
It works by keeping small "deposits" of water in the substrate. The retained water (and its added nutrients) is available to the roots of the orchids (and other plants) that will use it according to their needs growing around them.
Combined with the substrate in very small doses, it increases the retentive capacity of the substrate and its internal humidity.
Does it work with Lecca?
