Tips for designing Custom Planter Liners

From simple to complex installations, it’s best to compartmentalize your planting with modular liners to speed installation, limit potential drainage problems, minimize labor to rectify issues that may arise in the future.

Depending on size, DeepStream welds Plastic Planter Liners for your projects using 1/4″ to 1/2″ polypropylene, LLDPE, or HDPE plastic, as used in construction of both food equipment and large chemical tanks. Holes for side wall drainage and hidden irrigation lines can be added on site with a simple hole saw. 

Construction techniques may include double-welded gussets for optimum wall support.  Even with internal gusset to support liner walls, liners should be supported from the outside by a planter box or inserted into the ground for root control.

Polypropylene is extremely durable, however it is not impervious to the sun’s UV rays and should be completely buried or painted.  Although a little more costly Liners can also be made from Marine-Grade HDPE (high-density polyethylene) which is highly UV-resistant. Both plastic are food safe and used in kitchen equipment and food processing applications.

When a customer need a large volume of a certain size planter liner we custom form rotomolded planter liners our or recycled LLDPE plastic to reduce costs to a bare minimum.

Planter Drip Trays

Planter Drip Trays catch overflow and allow it to evaporate without staining your deck or interior floors.

The drip tray is sized so that the tapered base of the rotomolded Waterproof Plastic Planter sits inside it without taking up extra space.  Perfect for indoor and balconies.

Stock drip trays are approximately the same size as the lower step beneath the rim of DeepStream’s rotomolded liners and are sized to fit on Mariner planter aluminum liner support frames. Drip trays won’t be visible when used with DeepStream planters and they can be custom-welded to any size you need if you didn’t order a DeepStream Planter or rotomolded Waterproof Liner.

Custom Welded Drip Trays for indoor planters are also used on covered balconies to catch drainage, preventing stains on the floor or deck. The drip tray depth allows for evaporation of excess water.

As with all custom and semi-custom garden products produced by the hands of craftsmen, delivery times will grow longer as Spring progresses into Summer, even with “quick ship” programs, so plan ahead and order early.

Tips for improving Planter Drainage

Drain packs must be used in conjunction with a proper planting medium for container gardening, and inorganic filtering material to slow the drainage water so that any clay “fines” that could coat the geotextile will instead settle to the bottom of the liner below the side-wall drain.

  • When selecting your outdoor planters, keep in mind that drainage is critical to the health of your plants grown in containers, and it is very difficult to remedy after the fact. The design of the planter liner is one of the important components.
  • Generally, more tended plants die from drowning than from lack of water. “Old school” drain holes on the bottom and gravel drainage medium simply do not work and will quickly clog.  DeepStream elevates the drainage hole center approximately 2″ up the sides of your liners to provide a “reservoir” for the tap roots, but more importantly, that space allows clay “fines” present in all most all planting mediums to settle instead of clogging drain packs.
  • DeepStream pioneered modern drainage practices with side-wall drains and 3-layer drain filter packs. DeepStream places from one to three 3/4″ threaded drainage ports on its 16 stock proprietary plastic planter liners, to which various plugs, hose barbs and valves may be attached.  Liners are non-structural and are meant to be placed inside planter boxes.
  • Depending on your plants, planting mixture, and local climate, you may need to add more drains.  Additional drain holes can be added as required by drilling additional holes in the side walls with a hole saw bit. If additional threaded ports are needed we stock two-part watertight bulkhead fittings.
  • Planting mediums for container gardening are as varied as local climates and plant species.  Here in Florida, we can get 6” of rain in a day in the rainy season, so we need a quick draining material and we often add perlite. If you have a dry climate, you may need to add more vermiculite to retain water.  Since Florida also has a dry season where it my not rain for a month or more at a time, we use drip irrigation, as the planting medium we use for the rainy season dries out far too quickly during the dry season.  For more in-depth information on drip irrigation, drainage, and the many aspects of container gardening check the Helpful Resource Links to listed at the bottom of this page.
