Exo-Terra 12x12x12 Mini Viv Build
Start Date: 3/11/2011

To begin, I started with the vision to create a mini viv that would give the apearence of a small island found down inside a cavern. I want to give the viv the appearance of a water feature without using water and filter system.

The basic design begins with foam:
I utilized Great Stuff to close in the top three sides while incorperating a few places to put vines or plants to hang down into the cavern. Jiffy pots were used for plant locations by applying a small amount of Great Stuff on the glass, and then setting the pots into the foam.
I then apply more foam around the pots to enclose them.

Follow the instructions on the can and shake the can for 30 seconds or more. While using the spray, if the can sits for a long period of time you will need to cut off about 1 inch of the nozzle tip since the foamwill harden inside the tube.

I do only one side at a time as pictured below and wait out about 2 hours of set time to ensure the foam does not slide or move since it does expand dramaticly and takes some time to set.

Apply sparingly. The can states it will expand over 50 percent. If you apply too much it can be cut away and shaped once completely dried.

Note: If using accents such as branches, bark, or wood in the above areas of the background, the items should be siliconed into place prior to adding the Great Stuff.
