If you’re familiar with me on Instagram, then you know how important it is for me to provide my plant babies with the humidity they require. When I saw Root and Vessel’s Tri-Terrarium that came with the dome, I was instantly sparked with ideas on how I can use it in the apartment. First was the Forest Floor, a more traditional way of using the terrarium, as you can read here in Part 1. My second idea was using it as a humidity house which can be used for new plants that are acclimating to the apartment. This is in general perfect for plants that need that extra humidity to thrive.

PART 2: Humidity House

I hope to create and set up a vivarium this summer and filling it with jewel orchids, so I’ve been purchasing the plants I want as I find them. Since they require quiet a bit of humidity to stay happy, I thought keeping them here in the Tri-Terrarium was a perfect solution as a temporary home filled with humidity. Check out my steps below on how I step up this humidity house in the Tri-Terrarium and Napa Tray planter.


Now you can use this for any plant that might require more humidity, acclimating or regrowing. The concentrated humidity will really help.



  1. Tri-Pot Terrarium (Taupe color, *coupon code below*)

  2. Napa Tray (Taupe color, *coupon Code below*)

  3. 3 small Jewel Orchids ( feel free to swap these out with anything that might require more humidity)

  4. Slotted 3” Pots

  5. Hydro Balls (leca clay pebbles)

  6. Sphagnum Moss

Let’s Start!


-Rinse and dry all your containers and set the Napa Tray and dome cover aside. We’ll need it again later on.


-Remove the bottom black tray


-Flip your Tri- Terrarium planter over, we are going to keep the plug in for this set up.


-Start pouring in the hydro balls to create a base layer for the pots to stand on.


-Flatten them out trying your best to create an even surface


-Next, grab your 3 inch slotted pots and test if the levels are right. you want it to be fairly flush to the top.


-Once you have that set, start taking the plants out of their original medium and give them fresh sphagnum moss or soil.


-Since I’m working with Jewel Orchids, I’m going to want to plant them in sphagnum moss. For other plants that require soil, you can refer to my soil mix in Part 1


-Finish potting up your plant.


-Repeat for all your plants.


-Once your done, begin placing the potted plants into the Tri-Terrarium.


-Next, grab some more Hydro balls to fill in the space in between the pots.


-Once your all done, feel free to water or mist the plants.


-Go ahead and place the Tri-Terrarium on the Napa Tray and grab your dome cover.


-Lastly, I placed pebbles and water around the tray to act as another source of humidity. This step is optional.


Here’s how it turned out!


The great aspect of the dome part is that it has vents for air flow and circulation.

It also really helps keep the plants happy with humidity.
