Perlit je tepelně zpracovaná vulkanická hornina. Používá se k vylehčování půdy (má nízkou objemovou hmotnost, protože obsahuje velké množství kapilárních i nekapilárních pórů a tím zabezpečuje vzdušnost). Dále se používá jako regulátor půdní vlhkosti prodlužující účinek minerálních hnojiv.
It is used for rooting cuttings and for sowing larger flower and vegetable seeds. Keep the perlite moist after cutting the cuttings (sowing the seeds). Once the cuttings have been taken (seedling emergence), immediately start regular fertilisation with a combined fertiliser, as perlite does not contain nutrients. We recommend using Kristalon start fertiliser for fertilisation. Transplant the grown seedlings into a pre-prepared substrate, for example for houseplants, or for geraniums and balcony plants, etc. It is also used as an admixture in growing media, soil and peat to lighten and aerate these materials. In this case, it is mixed in a ratio of up to 1:3.
The product must be stored in dry places in undisturbed packaging separate from other fertilisers, food, feed and disinfectants and packaging for the above mentioned products. Keep out of reach of children. Store the bulk product in clean, paved, covered areas to prevent weed seeds from the surrounding area.
