Tri-Pot Sprout House Terrarium

Since this terrarium is quite versatile, follow the plant’s instructions on the appropriate recommended layering of potting media. For most plantings, add a small amount of activated charcoal on the bottom of the planter or on top of the insert. Then, top with a perlite medium, like small pebbles. Finish filling the planter to the bottom of the rim with a light to medium weight potting mix or the recommended potting medium for your plants. Routinely adding plant food, according to plant’s directions, will dramatically increase the health, beauty and fullness of the plants in your Tri-Pot Sprout House Terrarium.

The Tri-Pot Terrarium's base is constructed from Artstone material, which is a proprietary blend of resin, colorant, and crushed limestone. The result is a durable bottom planter that has a beautiful, marbled look. The dome lid is made from high-grade acrylic for clarity and durability.

Yes! The Tri-Pot Terrarium has an optional self-watering system called the Water-Minder. This removable insert creates a sub-irrigated reservoir at the bottom of the terrarium that allows water to seep through the screen. Your plants then absorb the water as needed. You can easily remove the insert for plants which require dry soil.

The Water-Minder self-watering feature prevents overwatering and underwatering as long as the drainage plug on the bottom of the planter is removed. This is because the water level will always drop to the top of the overflow drain. Your plant will then absorb the water as needed.

If you're worried about underwatering and/or if it's hard to tell if the plant is dry, then we recommend watering frequently to avoid any chance of underwatering. That ensures there is always water available in the reservoir. Just make sure the drainage plug is removed so that the water does not overfill the reservoir, potentially causing watering-logging and root-rot.

A saucer is not needed when using our planters indoors unless you decide to remove the drainage plug from the bottom of the planter. The only downside to keeping the drainage plug in is that you have to be mindful of overwatering. That is because with the drainage plug left in, any excess water will no longer automatically drop to the top of the overflow drain.

There is a removable drainage plug on the bottom of the terrarium. This allows the water level to drop to the top of the overflow drain.
