- Abstract:
- Indoor-greenery - Vegetation monitoring and laboratory analyses of different substrate-variants on their aptitude for indoor greenery. Due to the increasing popularity of indoor greenery and the accompanying market release of related products, the University of Natural Resources and Life Sciences, Vienna investigated four substrate-variants suitable for indoor greenery (naturally fired clay, different in grain sizes) in comparison to three already well established products (expanded clay pellets, expanded clay granulate and peat free potting soil). To get a significant result, two types of methods were combined: A vegetation monitoring over six months of three indicator-plants (for dry, moderate and moist habitats) planted in the seven substrate variants. Investigated parameters are: Vitality, length of sprouts, florescence, compressive strength and biomass (measured in a gravimetric and photometric way). To supplement the data, laboratory analyses were made to gather the chemical and physical attributes of the different substrates. Tested parameters are: settlement capacity, bulk density, water holding capacity, pH-value, salinity and nutrient levels of P, N, K. Naturally fired clay in grain size 2/4 shows the best results. It is suggested to develop a fertilizing strategy to improve the growing performance and vitality of the plants. The tested substrates, with grain size of 0/3 and 0/12 are not suitable due to their high proportion of fines. Expanded clay pellets and expanded clay granulate showes low results without fertilisation. Peat free potting soil must be evaluated seperatly becaus of the organic components. The combination of different methodologies (empiric vegetation monitoring and laboratory analyses) facilitated a holistic view on the subject and allowed to avoid misinterpretations. The comprehensive investigation and development of indoor greenery substrates are decisive as foundation of sustainable successful indoor greenery.
