The Two Background Styles

There are many ways to go about building a custom background, but we've found two styles to be the most long-lasting, best looking, and most consistently repeatable. Fully custom backgrounds rely on tools like foam, silicone, wood decor, and background texture mix to get the job done. These are a little more difficult to create, require more time, but have the absolute best looking results. Heavy duty backgrounds are basically modified cork tile backgrounds, with added 3D plant mounting points, animal perches, and more. These are the least expensive option we recommend, can be built very quickly, and easily support larger inhabitants.

Foam: Great Stuff Brand

A common choice for custom background builds

Great Stuff Foam
▾ Show Description ▾
This is the most common & trusted brand of foam used to build a custom vivarium background. After applying a thin layer of terrarium-safe silicone onto a glass enclosure, this foam can be sprayed-in to form ledges and other 3D effects. It's also great for filling gaps between wood decor during custom background design. Once applied and allowed to cure, it can be carved or left "as is" before it's coated with a layer of silicone & background texture mix for an awesome naturalistic effect. To learn more about custom vivarium backgrounds, check out our custom vivarium background how-to article.

Want more detailed texture & plant growth performance on your custom background? Our background texture substrate is a carefully blended mixture of Canadian organic peat moss, shredded coconut husks, and coconut fiber, and is designed to add a more detailed, darker, and three-dimensional texture than any alternative. The mix looks great on it's own even before plants grow on it, but it's also a great way to encourage Moss, Moss Slurry, epiphytic plants, and trailing plants to spread onto a custom background directly. Our Background Texture Mix is included at a discount in our Custom Background Kits, as well as our Heavy Duty Background Kits. For detailed instructions, please check out our Custom Background DIY article.

NEHERP Modular Cork Planters

Specially selected cork rounds cut at neat 45° angles for use as background-mountable planters

▾ Show Description ▾
Hover over the image for planter illustration
A New England Herpetoculture Product:
Our inexpensive modular cork planters allow vivarium builders to add a planting site anywhere they'd like on a background. These are compatible with Cork Tile Backgrounds, Custom Background Kits, and included (at a discount) in our Heavy Duty Background Kits. Depending on the type of background being created, Modular Cork Planters can be attached to an enclosure using either our terrarium-safe silicone or using stainless steel hardware. If silicone is used, any excess "push out" adhesive can be coated with Background Texture Mix to help the planter blend more seamlessly into the background. Both sizes have one opening cut at a 45° angle for easy mounting. Once a planter is mounted it can be left empty to be used as a cave/ledge, or filled with substrate to contain live plants. Over time the roots of plants will grow out & onto the cork itself, creating an awesome grown-in effect. Click here for a bare background fitment photo of the above enclosure.

Razor Extension Tool

Great for cleaning hard to reach glass and shaping/trimming custom backgrounds

Razor Extension Tool
▾ Show Description ▾
NEHERP Staff Description:
This is a very useful tool to have while working with larger vivariums. It can be used in a number of ways, but we use it most often to scrape hard-to-reach silicone off of the glass while building a custom background. These can also be used to scrape algae, water spots, and other things from hard-to-reach glass sections of established vivariums. Be sure the razor blade used on this tool is cleaned of all manufacturing oil before use. You must be at least 18 years of age to purchase this item.

Silicone Adhesive: Clear

Terrarium safe clear silicone

Clear Silicone For Terrariums
▾ Show Description ▾
NEHERP Staff Description:
A 100% non-toxic aquarium & terrarium safe clear silicone adhesive. These are from Marineland, one of the top manufacturers of glass aquariums. At the shop, we most commonly use clear silicone to repair or re-seal enclosures. The cured appearance is more clear than some of the other brands we've seen. If you'll be repairing a leaky corner in any aquarium, we recommend scraping out as much of the original silicone as is conveniently possible first, to help ensure a clean bond. Like the other types we carry, our Marineland silicone is restocked often from the distributor, to ensure a fresh & effective product.

Silicone For Terrariums
▾ Show Description ▾
NEHERP Staff Description:
These are the same 3oz containers of silicone we include in our Heavy Duty Background Kits, and they are perfect for getting smaller-scale jobs done right. These silicone tubes are especially great for mounting our Modular Cork Planters to background surfaces! Like the other brand we carry, this is a terrarium-safe silicone which is neutral cure and easy to apply. The included applicator tip can be cut at different spots to increase or decrease the size of the bead you'll apply. We order from the manufacturer every couple of weeks or so to ensure our stock is always fresh, in an effort to prevent issues with using older silicone. Available in either black or clear color, and sold in 3oz tubes.

Silicone Dispenser Gun

A heavier duty, no-drip, silicone gun

Silicone Dispenser Gun
▾ Show Description ▾
NEHERP Staff Description:
This is a heavier duty alternative to some of the economy caulk guns out there, and is the same model we use & recommend for silicone. Traditional caulk is more viscous and squeezes out much easier than silicone, so a traditional (pop-riveted) caulk gun typically won't hold up to the "abuse" of applying a thick silicone sealant. These welded models are the best option we've seen for the price, and have held up to even long-term frequent use at our shop. Their design also helps to minimize drips after it's used, as the "dripless" name suggests. We have a handful of these being used at NEHERP right now, and they are the same units included in our Background Kits.

Silicone Spreading Tools

Reusable tools for spreading silicone on custom backgrounds

Silicone Spreader Tool Silicone Spreader Tool
▾ Show Description ▾
These are used to spread silicone on the glass background of a terrarium as the first step towards building a custom background. For background work, these simple plastic knives actually work better than more expensive stainless spreaders because clean-up takes just a second after the silicone cures. When your project is complete, just leave the tool out for 12-24 hours to allow the silicone to cure. Once cured, it peels right off the tool with no mess! These are the same ones we offer in our Custom Background Kits. The 5in model is pictured above. Colors may vary.

Stainless Steel Terrarium Hardware Stainless Steel Terrarium Hardware Stainless Steel Terrarium Hardware

▾ Show Description ▾
High grade stainless steel hardware for affixing wood decor together, decor to backgrounds, and more. Our hardware packs are 304/Food Grade stainless, not common hardware store 10/0 or lower grade stainless steel. Kits include optional matching curved washers for securely mounting assorted decor items to cork backgrounds, although they are equally useful for attaching different wood decor together. The use of the curved washers allows for counter-sinking the hardware into the cork backgrounds to allow for flush fitment against the glass, while ensuring the hardware won't "pull through" as the enclosure ages. Note: Be careful that no sharp edges come through wood decor when mounting. Any exposed hardware can be coated in silicone, and covered in custom background texture mix for easy, discreet, and safe cover-up.

Tree Fern Panels

Great for backgrounds, plant mounts, and more!

Tree Fern Panels For Bioactive Terrariums Tree Fern Panels For Bioactive Terrariums
▾ Show Description ▾
NEHERP Staff Description:
Tree Fern Panels have been used to mount orchids & other epiphytic plants for decades. In a horticultural setting, plants are typically mounted to the boards, and the boards are hung for display. In a terrarium, tree fern panels can be affixed to the back or side panels of the enclosure to act as a 3-dimensional mounting point for plants. In custom background design, these Tree Fern Slabs can be broken up to fit into gaps and spaces left between other pieces of wood decor, to ensure epiphytic plants have the absolute highest chances of success. These are sustainably harvested from New Zealand, and the color will turn significantly darker once moistened.

Cork Tile Background For Bioactive Terrariums Example Of Custom Tile Background In Terrarium
Cork tile background shown heavily customized (right)
▾ Show Description ▾
NEHERP Staff Description:
Our drop-in Cork Tile backgrounds are made from natural Cork, and we've had a lot of luck with them over the years. We'd consider them our most cost-effective and durable solution for larger inhabitants, and are the same panels we include (to be modified) in our Heavy Duty Custom Background Kits. At about 5/8-3/4in thick, these cork tile panels are more durable than most alternatives. If you'll be building a humid bioactive terrarium, these background panels will support plants growing on them so long as the surface is kept sufficiently moist during acclimation. For maximum visual impact and climable textures, Cork Tiles can be customized by affixing other wood decor using High Tensile Strength Silicone, T-304 Stainless Steel Screws, and Custom Background Texture Mix.
