Ideal for germinating (even very fine) seeds or for covering seedlings. \u003cbr\u003e3.) Provides extra moisture retention without losing aeration. \u003cbr\u003eADDITIONAL INFORMATION: Perlite holds water in its vesicles, trapping water droplets in small 'chambers' or 'pockets'. Perlite is heated and expanded granite grit. The product therefore has something in common with popcorn: it pops just like corn on a hot plate. This additive is water-repellent itself, but has many pores that can store water and air. Perlite is a wonderful product: its few drawbacks are purely physical. For example, we must bear in mind that it is extremely light, and therefore has a tendency to rise to the surface every time the soil mixture is saturated with water. A second problem is that the product used for plant cultivation is WHITE. It may therefore be considered aesthetically unsuitable. In the greenhouse (especially in winter), a layer of Perlite on the soil is very beneficial for light reflection.\u003c\/p\u003e\u003cp\u003eDesignations:\u003cbr\u003eAlso: Perlite\u003c\/p\u003e","brand":"Vreeken","offers":[{"title":"5 litres","offer_id":44177588486197,"sku":"809650.1","price":2.5,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/9092\/3573\/files\/809650.jpg?v=1750793905","url":"https:\/\/www.vreeken.nl\/en\/products\/809650-1","provider":"Vreeken's Zaden","version":"1.0","type":"link"}
