Use rockwool as a substrate for Peperomia obtusifolia, Streptocarpus hybridus and Spathiphyllum floribundum

Zbigniew Strojny

Abstract


Two experiments were conducted, in which the granulated rockwool 'Grodan', utilised rockwool 'Flormin', used before as slabs and remained after 2-year carnation culture (UR) - shredded and steamed and two kinds of insulation rockwool of domestic production: from Gliwice (RG) and from Nidzica (RN) were used as a substrate or its ingredient for mentioned in title plants. Particular plant species expressed somewhat diversified reaction, but generally rockwool showed full usability as a substrate or its component. The best kind appeared to be UR. RG was good in the mix, where it was in 25% of the volume, but RN was unsuitable.
