• Weight- 900 Grams,

• 2-4 % Pumice dust will be available in this pack. This is the smallest size of pumice stones. Most of the plant lovers find this smallest size of Pumice (2-4mm) more suitable for soil conditioning (for mixing in soil) of Cactus, Succulents and other small plants. 

• If you wish to use for mulching (top soil layer), please do not buy this size of Pumice. As per our opinion, 4-8mm or bigger size of pumice is more suitable for top layer of plants. Mulching of Pumice does not attract fungus or insects.

• These smallest Pumice granules can be used as a better alternative for Perlite. Pumice stones do not break down so easily. Pumice helps plants in faster drainage also. However, Perlite breaks down in powder form easily and may clog the soil drainage. Due to these reasons, most of plant lovers prefer to use pumice stones in potting mix, instead of Perlite.

• 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.

• 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.

• All needful nutrients can be stored in the small holes of these stones for continuous supply to plants. Use of Pumice stones in potting mix of garden plants is considered as the best choice because it’s fully organic. Some plant lovers have successfully used Pumice (4-8mm or bigger size) for Hydroponic as well.

• 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.

• Use for Aquarium: Pumice stones are also used in Aquarium for water purification. Bacterial growth (inside air cavities of Pumice) helps in biological purification of aquarium water. 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.
