FLORAHUM - SS is a sterile substrate of uniform composition consisting of black and white peat types: the ratio of these peats gives the substrate good physical, chemical and biological properties, good stability and bonding of the components. It is enriched with all necessary macro and micro biogenic elements. The FLORAHUM -SS substrate is also enriched with a polymers based wetting agent for fast and more durable water-tightening. Wetting agent reduces the number of watering and thus the rinsing of nutrients in these, usually shallow settled substrates. It is not necessary to sterilize substrate before planting, but it should be ensured that post-infection of the substrate does not occur during sowing and breeding. Since sowing in this substrate is carried out in a shallow layer, it should be kept in mind that excessive watering can cause rinsing of the nutrients which leading to starvation of seedlings and frequent occurrences of illness. It is advised to follow the instructions on sowing density, climatic conditions of breeding, protection measures, regular ventilation, illumination and the like. In the case of poor and uneven rise of seedlings, it is recommended to apply the nutrients through the substrate or trough the leaf. Use combinations of liquid or crystalline fertilizers with an emphasis phosphorus and potassium quantities. We suggest combinations of 8:13:14; 14:10:34; 11:44:11 or a combination of 20:20:20 in case of a steady growth. When feeding over the substrate, use a solution of 1 g / L of crystalline fertilizer in water. If liquid fertilizers are applied trough a leaf (foliar) we also recommend combinations with emphasized phosphorus and potassium concentrations, but at quantities that is 50% lower than recommended in the leaflet. The treatment should be done earlier in the morning or in the cloudy weather, to avoid burns of plants. Fertilizing should be performed 10-14 days after plants starting in 7 to 10 days intervals. It is necessary to regularly monitor the health of the seedling and perform regular treating with appropriate protective measures recommended by experts. FLORAHUM - SS has a fine and homogeneous structure with a uniform particle size. This is achieved by repeated grinding, sifting and roughening. This substrate provides an ideal habitat for the seeds, as well as the smooth operation of automated loading systems for containers or different cassettes.
