Side Irrigation Feed

Advantages

  • Less Expensive

  • Easier to install

  • Thinner profile

Drawbacks

  • Requires 8″ or 16″ wide facing treatment at one or more ends of the installation.

Recommendations

Consider making a hinged facing material over irrigation feed lines for ease of future access for inspection and maintenance.

Rear Irrigation Feed

Advantages

  • Wall-to-wall coverage

  • May eliminate need for a side treatment (facing material)

Drawbacks

  • More expensive

  • Takes more time to install

  • Deeper profile

Recommendations

May require side treatment depending on site conditions and desired aesthetic. On new construction, consider recessed walls to reduce the living wall profile. For the plants to be flush with the adjacent wall surface, recess green wall area by 11 inches with Standard-sized planters and 13 inches for Large-sized planters. To conceal the thicker furring strips only, recess green wall area 5 inches.

WALL STRUCTURE IRRIGATION COMPONENTS

RainRail Irrigation Hook-Up

LiveWall, LLC supplies components from RainRail end to irrigation valve.

Please note:  The pipe and fittings required to hookup the mainline to the valves can vary greatly by site and thus are to be sourced by the installation contractor.

RainRail fittings connect RainRails to each other, the irrigation feeds, or cap the end of a run.

RainRail Fittings

  • Connects RainRail to other RainRails or irrigation feed, or caps the end of an irrigation run.
  • Designed with multiple o-rings for security against leaks.
  • Non-PTFE pipe lube included with each order for ease of insertion.

Plant Watering Components

Nearly without exception, drip irrigation is the preferred method for watering indoor living wall systems.  On outdoor systems, the preferred method can vary based upon plant type, site conditions, or local code.  In most cases, outdoor green walls are watered with spray nozzles that simulate rainfall.

Each RainRail has pre-drilled threaded holes for drip emitter assemblies or spray nozzles. No tools are required nor should they be used to tighten nozzles in each rail.  Over-tightening can damage parts and impair function.

LiveWall "tool-free" irrigation nozzles available in 3 colors / flow rates.

Spray Nozzles

  • Available in 0.1, 0.15, and 0.2 GPM flow rates.
  • Molded components resistant to calcium buildup.
  • If a single valve supplies water to more than one row, higher flow rates are used on upper rows and lower flow rates are used on lower rows to equalize water pressure and delivery.
  • With each order, LiveWall to supply shop drawing with site specific nozzle flow layout.
LiveWall drip emitter assemblies are used primarily on indoor projects, may be used outdoors.

Drip Emitter Assembly

  • Each assembly consists of T-fitting, two 8″ long tubes, and two flow stakes
  • 0.5 GPH flow stake elbows (1 GPH total per assembly) used on all lower rows
  • 1 GPH flow stake (2 GPH total per assembly) used on top row, which dries out the most quickly

  • LiveWall may supply a liquid fertilizer concentrate.
  • Follow dilution instructions prior to use (using too high of fertilizer concentration may damage plants).
LiveWall may provide descaling components for hard water treatment to prevent nozzle clogging / impaired water flow due to calcium buildup.

Descaling Housing and Cartridge

  • Recommended for use when mainline supplies hard water
  • Use 2 sets per main line where spray irrigation is used
  • Use 1 set per main line where drip irrigation is used
A hose timer may be used on outdoor walls up to 64 square feet.

Hose Timer

  • In lieu of controller, valve and pressure regulators, a hose time may be used on small outdoor green walls (up to 64 sq ft) near a hose spigot.
  • Fittings included to hook LiveWall irrigation feed lines and hose timer.
  • Customer or contractor to supply hose.

The LiveWall System requires an irrigation feed that is capable of providing sufficient water volume and pressure for each irrigation zone.  The backflow preventer should be hooked up to a feed line that is at least 25PSI, not to exceed 85 PSI.  Pressures over 85 PSI may damage fittings and lead to leaks.

Each valve requires 8-10 gpm per valve (zone), regulated to 15psi pressure, via pressure regulators that are placed upstream of each valve.  In some cases, a booster pump may be required to ensure that the upper valves receive sufficient pressure and flow to water the planter array evenly.

LiveWall quotes mainline irrigation components for each project, and this includes backflow prevention, irrigation controller, and a micron filter to keep any waterborne debris from plugging up the irrigation nozzles.  Installation contractors must source pipe and fittings to connect mainline to the irrigation valves.

LiveWall mainline irrigation hookup pressure and volume requirements.

Descaling Cartridges Ensure Water Flow

Properly treated hard water poses no health risks and actually provides beneficial nutrients to LiveWall plants. However, buildup of calcium or iron scaling from untreated hard water can potentially impair the flow of water through the irrigation nozzles. The cost of treating hard water is not an expensive add-on to a LiveWall System installation.

In cases of hard water, use phosphate descaling system to prevent irrigation system blockage or failure.  This can be purchased from LiveWall.  Descaling cartridges should be replaced annually and can be reordered from LiveWall.

Descaling cartridges help with hard water.

Large Projects

Very large projects (over 2000 square feet) may require additional treatment. On larger walls, an alternative chemical treatment system may be preferred.  In these cases, LiveWall recommends CH2O, Inc.

For a free water test to determine the type of hardness, how much is in the water, and the cost of treating 10,000 gallons of your water, send them a sample.

The recommended method for fertilizing LiveWall systems depends upon the water delivery method and whether a fertilizer injector was installed on the irrigation mainline:

A chart of LiveWall fertilization options based on watering method.
LiveWall recommends fertilizer injector for drip-watered living walls over 100 square feet in size.

Automatic Fertilization

LiveWall systems may be purchased with a fertilizer injector that is tied into the irrigation system.

The fertigation system injects a low dose of fertilizer each time your living wall is irrigated.

LiveWall supplies an organic liquid fertilizer concentrate that must be diluted prior to use.  For more information, download the injector operation and dilution instructions.

Granular controlled release fertilizer recommended for hand-watered green walls or those with spray irrigation.

Manual Slow Release Granular Fertilizer

Outdoor walls and hand-watered indoor walls may be fertilized once annually using a granular slow release fertilizer such as Scotts Osmocote®.

A single spring application is usually sufficient to feed plants through the growing season.  Shake one teaspoon of fertilizer evenly across the soil surface of each full-width, Standard sized wall planter.  Apply half as much for half-width Standard size planter and twice as much for Large planters.

Liquid fertilizer may be manually applied to LiveWall systems with any type of water delivery method.

Manual Liquid Fertilizer

Every 6 to 12 months, indoor or outdoor living walls which do not have automatic fertigation may be fed with a higher concentration of liquid feed.

Fertilizer may be applied manually according to the label directions using a watering can or a hose.

IMPORTANT: Do not use granular fertilizer for indoor walls with automatic irrigation. The granules require water to run over the surface to activate, and LiveWall indoor systems include drip stakes that inject water directly into the soil.

Application rates will vary with formulation.  In all cases, follow directions on package label.

All applications of fertilizer are the sole responsibility of the applicator.

COMPONENTS SOURCED BY INSTALLER

The components described above are typically supplied by LiveWall as a part of a wall structure’s delivered price.  The following products would be sourced by the installation contractor, using components suited to each project’s specific application.  LiveWall strongly recommends for designers or builder to specify desired materials to be sourced by installation contractor.

Anchors for Structure to Building Wall

Appropriate wall anchor, specify non-corrosive screw, length, head, point, and type of fastener appropriate for wall application and local codes, used to attach vertical furring strips and brackets to hold facing material covering irrigation feed.  Some suggested fasteners are listed in our FAQ section.

Please Note: LiveWall, LLC provides furring strips that provide flexibility in living wall design over a number of different applications.
The exterior wall design and means of fastening the vertical garden to the building wall are ultimately the responsibility of the local architect and/or structural engineer and installation contractor.
