It’s no secret that terrariums are gaining popularity. And why wouldn’t they? These “mini greenhouses” of sorts are adorable, low maintenance, and the perfect way to green up indoor spaces. We love our plants (we are your buds you know!) and we have a lot of indoor plants in our offices. So we thought – why not find a way to bring our two worlds together: house plants and recycling! We’ve taken the classic enclosed terrarium and “greened it up” even more by reusing an empty 2 liter soda bottle for the container: a simple plastic bottle terrrarium! Read on to learn how to create your own soda bottle terrarium and create a mini organic (and recycled!) space for your plants.

Choosing the Right Materials: Soil & Plants

What plants are best for your terrarium? Select humidity-loving plants such as the ones we used, the Umbrella Plant, and Peperomia, which has many different variations. These plants thrive in an sealed enclosure and will create their own mini eco-system!

It’s always a good idea to use nutrient-rich, organic soil. In addition to your soil, it’s important to use fine sand, pebbles, and activated charcoal so that your plants are able to absorb only as much water as needed and to prevent mold/mildew from growing inside of your terrarium.

Choosing the right plants and soil will ensure that your mini eco-system thrives and requires minimal care/watering.

Recycled Bottle Terrarium: Instructions

Step 1: Place a rubber band around your empty, clean soda bottle.

You’ll want the rubber band to be as level as possible, and to sit just below where the bottle begins to flare outwards. This is where you’ll cut your bottle.

Step 2: Cut just above the rubber band.

Use a box cutter to “stab” a hole in the bottle, then use a scissors to cut the rest of the way around. Trim about 1″ off the bottom of the top half of the bottom as well.

Step 3: Pour 1/2″ sand into the bottom.

Step 4: Add a layer of pebbles.

The sand and pebbles will help with water drainage, ensuring that your plants don’t become water-logged.

Step 5: Add the activated charcoal.

Activated charcoal (which can be found at many pet, craft, and gardening stores) helps in preventing mold and mildew from growing inside your terrarium.

Step 6: Add a 2-3″ layer of organic soil.

Poke holes in the soil where you want to put your plants. Why Organic? Because we love Mother Earth and want to keep thing eco-friendly and organic whenever we can.

Step 7: Cut apart plants using a small knife or garden shovel and insert into the holes in your soil.

Add a bit of water to allow the plants to settle into their new home!

      Activated Charcoal rids the soil of impurities and prevents mold and odors. And, since activated charcoal is extremely porous, it will prevent root rot. You can build a terrarium without it too but if you want it, you can find it in the plant section of your local nursery or hardware store 🙂
