Signs
Signs can often become an important accessory for keeping orchids. We can record on them the Latin name of the orchid, the date of its last repotting, the time of the next fertilizing, etc ... Especially useful in larger collections where it is often difficult to tell the exact and complete Latin name of a Cattleya for example by pre-flowering or post-flowering. The most ideal graphite pencil to write this information is because it is erasable, timeless (does not dim the sun) and waterproof.
