Drafts Interior greenwalls should not be subject to drafts of hot or cold air. Even a rapid change of 15 to 20 degrees has the potential to damage plants. Consistent temperatures are best. Temperature Interior greenwalls are designed using tropical and semi tropical plant materials that are adaptable to our human comfort zones. Therefore it is generally recognized that a temperature of 72 degrees Fahrenheit in the winter and 75 degrees Fahrenheit in the summer is acceptable. Night temperatures can be 10 degrees cooler, or between 62 to 65 degrees F. Finishes of Surrounding Areas A greenwall system generates humidity. It is probable, through routine operation and maintenance, that some dripping or splashing will occur. This should be taken into account when determining the finishes around the greenwall system. Storage Provisions should be made for the storage of gardening materials and supplies. This storage should be readily available to the horticultural staff members who care for the plantings. Additionally, this area can function as the location of the greenwall’s irrigation controller. Safety and Serviceability The challenge in managing a vertical garden is the safety and serviceability of the plantings. Specifically designed lift systems or ladder systems must be included to facilitate routine maintenance. Maintenance Professional maintenance of the plantings should be accounted for when budgeting and planning. Special attention must be given to pruning plant materials in order to maintain balance between plant size and root growth. Regular plant grooming to remove dead and dying foliage, should also be accounted for and systems should be designed to facilitate these activities.
