ᐅ KALLAX for Large Plants – Has the Moisture Issue Been Resolved?

TahirHello everyone,
I’m starting a discussion on the topic: “KALLAX for large plants – moisture problem solved?”
Recently, I used my KALLAX shelf to accommodate tall indoor plants. The concept seemed practical: storage and plant stand in one. However, I soon noticed that the moisture coming from the plants, especially from the wet saucers, gets trapped inside the shelf, creating a damp and clammy indoor climate.
My question is whether any of you have experience with how to permanently manage this moisture issue with large plants in KALLAX shelves? I’m particularly interested in solutions that protect both the engineered wood material of the shelf and keep the plants healthy over time. Specifically, I’m thinking of ventilation options, sealing methods, or special inserts.
It’s important to me that the solution is practical for everyday home use and not too complicated. If you have any tips on materials or construction methods that have worked well, please feel free to share.
Thanks in advance for your contributions!

Regarding the “moisture problem solved” question with KALLAX and large plants:
I looked into this topic in detail some time ago. KALLAX shelves are made of particle board with a melamine coating. These materials are prone to swelling damage when exposed to moisture over a long period. The combination with large plants, which are watered regularly, significantly increases the risk of moisture damage and mold growth.
From my experience, a practical solution is to use a waterproof liner under the plant pot, ideally a plastic tray that is completely sealed and collects any water. Equally important is providing ventilation for the shelf compartments, for example through small holes or channels between the separate compartments.
Additionally, a spacer frame between the plant pot and the shelf surface can prevent moisture from coming into direct contact with the wood-based panel.
However, sealing alone without air circulation can only shift the problem and may even promote mold growth, as the moisture remains trapped inside.
In summary: combining a waterproof base, ventilation, and spacers is the most sustainable solution.

Drill air holes and use a saucer with drainage.

I can only agree – plants in the KALLAX are theoretically great, but practically a bit of a water trap 😉
What I did: I cut small ventilation slots with some spacing into the shelves and additionally placed waterproof silicone mats under the pots. This prevents the wood from becoming damp and allows better air circulation. Result: no more musty smells, no stains.
Bonus tip: place the pots on small feet or corks – this further reduces contact with the shelf surface. You can also make small spacers from a piece of wood.
Plant lovers combining these methods can hope to have solved the moisture problem ;-) 🍀

Your question addresses exactly the core issue many face when placing large, moisture-intensive plants on KALLAX shelves.
In my view, a multilayered approach is essential. The first step is to fully understand the material properties of KALLAX (particle board + melamine resin). These materials are not waterproof and react to moisture by swelling and shrinking.
As mentioned in previous posts, a waterproof barrier is therefore necessary. I deliberately do not recommend silicone mats, as these can trap moisture, but rather waterproof plastic liners with a slight slope to allow excess water to drain away.
In addition, ventilation of the shelf compartment should be ensured. Ideally, there are openings that allow air circulation without letting in dust or pests.
I find this point very important. It’s not just about moisture protection but also about maintaining good air quality around the plant’s location.
Finally, I recommend using moisture meters to regularly check that the humidity level around the KALLAX remains within a safe range. This is the only way to avoid long-term damage.
I’m happy to provide more details on waterproof materials and ventilation concepts if you’re interested.
