Orchids thrive in environments with good air circulation and drainage, making extra large #8 sized sponge rock an ideal growing medium. Its porosity helps prevent waterlogging and promotes healthy root growth, while its lightweight and easy-to-handle nature makes it a popular choice for various orchid growing applications.

When used in orchid cultivation, #8 sized sponge rock can help provide a stable root environment by improving aeration and preventing soil compaction. It can also help maintain a consistent moisture level around the roots, allowing for optimal nutrient uptake and growth.

1 gallon. 

It is recommended that when working with sponge rock, you wear protective clothing, a respirator and work outside in a well ventilated area.

This was a lot larger than I expected. It will work really well in my big cattleya pots!

The size of the sponge rock is perfect for Cattleyas and other epiphytic orchids that love humidity around their roots but not moisture! I would like to be able to order a larger quantity for a wholesale price. That's the only drawback I have because I will go through this little bag very quickly with a collection of over 300 orchids!
