“…Proses pembuatan rockwool yang melibatkan suhu tinggi membuatnya steril dari mikroorganisme patogen, hama, ataupun benih gulma. Air juga mudah terlepas dari serat-serat rockwool sehingga struktur rockwool memberikan rasio air dan udara yang optimum bagi pertumbuhan tanaman (Bussell & McKennie, 2004). Rockwool bersifat inert secara biologis dan kimiawi sehingga penggunaannya tidak akan memodifikasi atau membatasi suplai nutrisi bagi tanaman.…”

“…Rockwool bersifat inert secara biologis dan kimiawi sehingga penggunaannya tidak akan memodifikasi atau membatasi suplai nutrisi bagi tanaman. Lebih dari 98% air dan unsur-unsur hara dapat diserap oleh tanaman dalam sistem hidroponik dengan rockwool sebagai media tanam (Bussell & McKennie, 2004). Meskipun demikian, penggunaan rockwool dianggap belum berkelanjutan, dan seratnya pernah diduga memicu kanker paru-paru (Drent et al, 2000;Bussell & McKennie, 2004).…”

As the human population rises, the demand for high nutritional foods, such as green vegetables, also increases. However, agricultural land, especially in urban areas, is increasingly narrowing. Hydroponics can be one of the solutions to answer this problem. In addition to complete nutrition, hydroponic plants also require appropriate media for root attachments, water absorption, and aeration. However, no studies have compared the growth of hydroponic plants using rockwool and sponge as affordable growing media. Therefore, this study aimed to determine the effect of local rockwool, imported rockwool, and sponge as growing media on the growth of spinach (Amaranthus sp.) and green lettuce (Lactuca sativa) using Deep Flow Technique (DFT). This study used a Completely Randomized Design with three treatment groups, i.e., three different growing media, for spinach and lettuce. At the harvest period, the number of leaves on each plant was counted, the crown fresh-weight was balanced, and the chlorophyll content was determined. Plant height was also measured for spinach. The results showed no significant differences in all observed parameters except for the crown fresh-weight of the lettuce. The crown fresh-weight of the lettuce grown on sponge media was found to be the lowest significantly (81.47 ± 9.50 g) among all treatment groups. Other hydroponic growing media’s influences can be investigated for further research, with additional growth parameters such as crown dry-weight, root fresh- and dry-weight, as well as the determination of plant phytochemical contents. Moreover, the composition of nutrients can also be further examined to reveal the type of growing media and nutritional formulations that are most optimum for hydroponic spinach and lettuce growth.

“…However, it is important to note that the disposal problem for mineral wool has led to criticism of its current usage. Some authors, such as Bussell and Mckennie [19], showed some options to reuse rockwool, but when analyzing the life cycle assessment of horticultural growing media, Quantis [20] reported that mineral wool has the highest negative impacts on human health. In addition, freight costs are relatively high.…”

Increasing Sustainability of Growing Media Constituents and Stand-Alone Substrates in Soilless Culture Systems

2019

Decreasing arable land, rising urbanization, water scarcity, and climate change exert pressure on agricultural producers. Moving from soil to soilless culture systems can improve water use efficiency, especially in closed-loop systems with a recirculating water/nutrient solution that recaptures the drain water for reuse. However, the question of alternative materials to peat and rockwool, as horticultural substrates, has become increasingly important, due to the despoiling of ecologically important peat bog areas and a pervasive waste problem. In this paper, we provide a comprehensive critical review of current developments in soilless culture, growing media, and future options of using different materials other than peat and rockwool. Apart from growing media properties and their performance from the point of view of plant production, economic and environmental factors are also important. Climate change, CO 2 emissions, and other ecological issues will determine and drive the development of soilless culture systems and the choice of growing media in the near future. Bioresources, e.g., treated and untreated waste, as well as renewable raw materials, have great potential to be used as growing media constituents and stand-alone substrates. A waste management strategy aimed at reducing, reusing, and recycling should be further and stronger applied in soilless culture systems. We concluded that the growing media of the future must be available, affordable, and sustainable and meet both quality and environmental requirements from growers and society, respectively.

“…Some plants even survived without any fogging in GRW. One possible reason for this observed survival of plants is that both GRW and RWC have excellent water-holding and aeration characteristics [26]. Moreover, GRW has a higher number of large pores among particles that are more conducive to rooting than RWC, thus some plants even survived in the absence of fogging GRW.…”

An Optimal Combination of the Propagation Medium and Fogging Duration Enhances the Survival, Rooting and Early Growth of Strawberry Daughter Plants

2020

Runner propagation is an important process in strawberry cultivation, which influences plant survival and fruit yield during the commercial production. In South Korea, this process is carried out on plug tray benches that are set off the ground in greenhouses, rather than in open fields. During the propagation, the propagation media and fogging systems play an important role in the survival and rooting of daughter plants. The aim of this study is to investigate the influences of the different types of propagation media and various fogging treatments on the rooting and early growth of strawberry daughter plants. Two strawberry cultivars—‘Maehyang’ and ‘Seolhyang’—in a glasshouse, grown in four different propagation media-a peat moss-based mixture (PBM), rockwool cube (RWC), granular rockwool (GRW), and a coir-based mixture (CBM)—combined with five fogging durations, 0, 3, 6, 9 and 12 days were tested. PBM with 9–12 days of fogging was the most ideal combination for the rooting and early growth of daughter plants of the two strawberry cultivars, which increased the ratio of survival and rooting, number of new leaves, root length and maximised the fresh and dry weights of the aboveground and belowground runner biomass. However, fogging treatments shorter than 9 days led to a lower survival rate and rooting. RWC and GRW are not recommended for young plants of these two strawberry cultivars because their strong water-retentive properties could subject the root to water stress, which can lead to root rotting. The purpose of this study is to provide a reference for strawberry growers to improve the quality of plants and efficiency of production during the propagation period.
