Weight of this pumice pack is 450 Grams. The pack will be sent upon the basis of weight. Approximate volume of this pack will be 1.5 Ltr.
-
Size of these Pumice Stones will be in range of 30 to 50 mm. Most gardeners prefer this size of pumice stones for Orchid potting soil, Adenium, bigger Bonsai and other big plants. Due to bigger size, air cavities inside them are bigger and suitable for Orchids. With use of a hammer, we can easily break the Pumice into smaller pieces(as per our requirement).
-
Some nature lover also prefer to use with outdoor fruit bearing plants also so that pumice can provide nourishment to tree for long life. If you wish to use Pumice for mulching (top soil layer) of Adenium and other bigger plants, this size is correct choice, as per our opinion. Mulching of Pumice does not attract fungus or insects.
-
Pumice stones have porous composition and they are much lighter than ordinary stones. They contribute in soil aeration also. Pumice improves the quality of soil because of its porous properties.
-
They retain moisture in optimum quantity and provide needful micro-nutrients continuously to plants’ roots. Pumice stones ensure proper drainage in soil. All nutrients can be stored in the small holes of these stones for continuous supply to plants.
-
Pumice stones are naturally made from volcanic rocks and therefore they are not found naturally in India. These stones are imported from other countries where Volcanoes are available.
-
Pumice stones have been successfully used in Bonsai plantation and other plants in Japan for a long period. Use of Pumice stones in potting mix of garden plants is considered as the best choice because it’s fully organic. For organic farming, use of these stones is increasing.
-
They are also used in water fountains and landscaping. Pumice stones are light weight, hence we can use them for covering soil around plants. By doing so, they do not put load pressure over the soil under them. Your aerated potting mix continues to ensure root aeration.
-
Moreover, volume of these pumice is more than stones, hence in purchase of less pumice, you can cover more area of soil with pumice cover. On contrary, if you buy stones/pebbles, you need to spend more for buying more weight of stones. However, if we use traditional pebbles /stones over soil of plants, roots aeration is hampered upto some extent due to heavy weight of stones. In addition to this, stones are not capable to absorb moisture. But Pumice stones can very easily absorb moisture and contribute in creating humid atmosphere around plants and succulents. Requirement of humidity is most important, especially during hot summer.
-
Ph value of pumice is neutral, it is neither acidic nor alkaline. Pumice stones have a tendency to absorb atmospheric moisture, hence we may observe small droplets inside this pack, as a result of evaporation during hot weather. We have shown here all the 4 sizes of pumice available with us for reference of our customers.
-
For experiment, we mixed samples of all four sizes of Pumice stones and tried to submerge in water filled glass pot (image is shown for your reference). We observed that If size of Pumice rock is big enough (bigger than 15mm), we can easily see most of them floating over water due to light weight and availability of more air cavities inside pumice rocks. But, if we break them into smaller pieces, air cavities of pumice gets filled up with water and find it bit difficult to float on water. But surprisingly, more than 50 % of 2-4mm Pumice stones were also seen floating on water surface. Bigger Pumice showed more chances of floating.
-
Some plant lovers have successfully used Pumice (4-8mm or bigger size) for Hydroponic as well.
-
Use for Aquarium: Pumice stones are also used in Aquarium for water purification You have to wash it many times before using in aquarium, otherwise water of aquarium may look milky. It is suggested that you may use appropriate water filter also for aquarium to minimize its milkiness (if required). If you are having marine aquarium, use of Pumice as bio filter media is more useful.
Customers Purchase Behaviour of last four years:
We can use any size of Pumice, but due to larger size of Pumice, it will be easier to clean them with any brush during scheduled cleaning of aquarium. Our 50 % aquarium lover customers preferred 30-50mm size of Pumice for Aquarium. Our 25 % aquarium lover customers preferred Pumice size (9-15mm)for Aquarium. Left over 25 % customers purchased 4-8mm or even smaller Pumice (2-4mm) because these customers believed that smaller pumice will have more surface area and bacterial growth will be more with them. Presence of more bacteria is helpful in biological filtration of aquarium water.
A plastic mesh net can be used to keep these pumice stones with some pebbles at bottom of aquarium. By doing so, these pumice will not float on the surface of water and they will settle on bottom of the aquarium. Due to their light weight, these pumice stones keep on floating over water. They have small air pockets inside them.

I used this pumice in my aquarium as biological water filter. My fishes are enjoying. Most of the pumice are floating in water. I used a weight to keep them suspended in water. Also using smaller pumice in orchids potting medium as per advise of some experts.
