Open Top Terrariums

LIGHTING:

Open top terrariums require high amounts of light, so keep them in a bright spot but out of direct sunlight as this could cause the contents to overheat. Similarly, keep your terrarium away from radiators or other heat sources that could cause overheating.

WATERING:

The amount of water your terrarium needs depends on two main factors: a) How ‘open’ your terrarium is to allow air flow and evaporation, and b) the types of plants enclosed.NEVER pour water into your terrarium. Water should be added a little at a time using a misting bottle to avoid overwatering, as there is nowhere for excess water to go.
 

MAINTENANCE:

If you see any dead or dry leaves, remove them immediately from the terrarium to avoid the unwanted spread of mould or fungus. Leaves that are pushed up against the glass of the terrarium have a tendency to get too damp and rot, so remove if possible. Plants that have overgrown the terrarium can either be pruned back or replaced. Note that plants prefer to be pruned during spring and summer months, so we don’t recommend any pruning to be carried out over winter.

Open top cacti and succulent terrariums
Always check moisture levels before watering, and only water when the soil is powder dry (if in doubt, don’t water it). In winter the plants will consume much less water than in the summer months, and are at risk of rotting if the terrarium contains any excess moisture. Condensation on the glass or water in between the stones in the bottom are signs that there is way too much water in the terrarium. If this is the case, remove any lid and leave in a bright warm spot to dry it out. Unfortunately at this stage it is often too late to rescue your plants!
 
What we do:
In winter we check our cacti and succulent terrariums every 4 weeks, and water them lightly every 4-6 weeks or less. In summer months during it’s growing season, your terrarium will need more water. In the height of summer we check ours weekly, and water lightly every 1-2 weeks. N.B. We only water them if they’re dry, regardless of how long it has been since they were last watered.
 
Open top leafy green terrariums
If your terrarium has large droplets of condensation on the glass, then it has plenty of moisture and shouldn’t be watered. Remove the lid if it has one, and make sure that it receives adequate light and airflow across the opening to aid drying. However, keep in mind that a balanced terrarium will have some moisture on the glass. If the terrarium glass is clear, check if your terrarium needs watering by placing your finger in the top moss layer as well as into the moss to the soil underneath. If the moss and/or soil is beginning to dry out, mist the terrarium in small doses. Larger terrarium plants can receive extra water with a spray bottle at the base of the stem to ensure water gets into the soil underneath the moss layer. N.B. you can always add more water but can’t remove it so easily!
 
What we do:
We check moisture levels in our open top terrariums every 7-10 days during winter months, and check them at least once a week during the summer months. If the weather gets really hot and dry, we check our terrariums daily and keep misting them little and often.
