Orchid Bark
The most common Orchid Bark is Fir Bark. This usually comes in three grades (fine, medium, coarse). The finer the bark, the slower it dries but also lesser airflow. So for orchids that don't like to dry out, such as Paphiopedilum, use a fine grade. For orchids and tropicals that like a lot of airflow and want to dry quickly, such as Cattleyas, use a coarse mix.
Lava Rock
Lava Rock - Lava rock is an excellent base for an inorganic rock mix. Many times if you get a Dendrobium you will notice that it has been potted in either black or red volcanic rock. Lava rock has good water retention with excellent aeration. Because it is inorganic, the mix will not break down and orchids that resent repotting can be left in their mix longer. Bonsai also benefit from airy lava rock
Pros: Never decomposes; drains well; excellent aeration
Cons: Heavy
Leca
LECA stands for Lightweight Expanded Clay Aggragate.
Leca look like little clay balls. They are an inert substrate that doesn't break down or contain any nutrients for plants. Leca is often used with a self watering container. The false bottom holds a reservoir of water that through capillary action gets sucked up by the Leca while keeping the plants roots from sitting in water. The Leca keeps water available to the plant roots when they want it and prevents root rot.
Another advantage of Leca is that it makes for an inhospitable place for pests to live. Leca gives off no nutrients, doesn't decompose and doesn't allow root rot. Lots of common plant pests require many of those things to survive.
Pros: Never decomposes; drains well; excellent aeration, colorful options
Hi! I love your orchid bark, I was curious to know if I can purchase small medium and large bags. I don’t see it in Amazon or here anymore 😕🙁
