Introduction: Why Shelves Are the Heart of Your IKEA Greenhouse

If you’ve ever fallen down the Instagram or Pinterest rabbit hole of lush, glowing plant cabinets, chances are you’ve seen the IKEA greenhouse trend. What started as a DIY experiment among plant hobbyists has blossomed into a global movement — transforming humble IKEA display cabinets into thriving, climate-controlled mini jungles.

At the heart of every stunning IKEA greenhouse? The shelves.

Shelves are more than just places to rest your plants — they determine airflow, light penetration, humidity levels, and the visual balance of your setup. The right shelving can mean the difference between a healthy, lush cabinet and one that constantly struggles with mold, drooping leaves, and uneven growth.

In this guide, we’ll cover everything you need to know about IKEA greenhouse shelves — from choosing the right material and size, to installing them like a pro, styling them for plant health and aesthetics, and accessorizing for the ultimate indoor oasis.

What Is an IKEA Greenhouse Cabinet?

The Rise of the IKEA Greenhouse Trend

The IKEA greenhouse phenomenon exploded in online plant communities around 2019. Plant parents discovered that IKEA’s sleek, affordable cabinets — originally designed for books, décor, or glassware — could be converted into beautiful, functional greenhouses for tropical plants.

Why the hype? They offer:

• Climate control — Enclosed space retains humidity and warmth.
• Space efficiency — Perfect for small apartments or homes.
• Customizability — Shelves, lights, fans, and accessories can be tailored to your needs.

Why Shelves Are the Core Element

Shelves define how your plants are displayed and how light and air circulate. They create vertical growing space and allow you to group plants by their needs — orchids up top, foliage plants below, propagations in the middle.

Popular Cabinet Models for Greenhouse Conversions 

• Milsbo – Tall and slim, perfect for vertical setups.
• Rudsta – Comes in tall and wide versions, modern and versatile.
• Fabrikör – Retro glass-and-metal vibe, smaller footprint.
• Detolf – Narrow and tall, often used for smaller plants or budget builds.
• Baggebo – Affordable starter cabinet, lightweight and customizable.

IKEA Greenhouse Shelves Explained

Types of Shelves

• Acrylic – Lightweight, durable, humidity-resistant, excellent light transmission. (Highly recommended — shop our custom acrylic shelves here)
• Glass – Sleek, high light penetration, but heavier and more fragile with no ventilation or electrical cord management.
• Wire/metal – Great airflow, but can rust or look industrial if not styled. Can get especially messy if you have smaller planters that may tip over between the wire bars.
• Wood – Aesthetic warmth, but less humidity-resistant unless sealed.

Why Acrylic Shelves Win for Most Builds

Custom acrylic shelves offer the best of both worlds — they’re clear like glass but much lighter, shatterproof, and easy to clean. Plus, ventilation cutouts or corner designs improve air circulation for healthier plants.

Sizing & Compatibility by Cabinet Model

Each IKEA cabinet has unique internal dimensions. Choosing the right fit ensures stability and prevents tipping or stress on the frame. (We design shelves specifically measured for Milsbo, Rudsta, Fabrikör, Detolf, and Baggebo models.)

How to Choose the Best Shelves for Your IKEA Greenhouse

Factors to Consider

• Weight capacity – Can your shelf hold a large ceramic pot with wet soil?
• Airflow – Solid shelves may block circulation; perforations help.
• Light penetration – Clear or open designs allow light to reach lower plants.
• Humidity resistance – Essential for avoiding warping, rust, or mold.

Matching Shelves to Your Plants

• Orchids – Benefit from slatted or ventilated shelves for airflow.
• Foliage plants – Prefer even light; clear acrylic helps distribute it.
• Propagation stations – Need stability for jars and vases.

Mistakes to Avoid

• Using untreated wood (mold risk)
• Overloading shelves with heavy pots
• Blocking airflow completely with dense layouts

Accessories That Take Your IKEA Greenhouse to the Next Level

Lighting Systems

Full-spectrum LED grow lights are a must. Mount them above each shelf and the ceiling of your cabinet to mimic natural sunlight and avoid shading lower levels.

Ventilation Fans

Small USB or 24V DC fans keep air moving, preventing fungal issues. (See our fan mounting solutions here.)

Humidity Control

Use misters, foggers, or simple water trays. Hygrometers help monitor conditions.

Versatile Pegboards & Hooks

Pegboards add style and function — perfect for tools, plant tags, or mini pots. (Feeling fancy? Explore our Golden Hour, Flower Petal, and Holographic pegboard designs.)

Installation Guide for IKEA Greenhouse Shelves

Tools & Hardware Needed

• Measuring tape
• Shelf brackets or mounting hardware
• IKEA usually provides some brackets with the purchase for your cabinet, however we recommend extended brackets for Milsbo, Rudsta and Fabrikor for extra support when you are working with various shapes of custom shelving.
• Screwdriver

Step-by-Step Shelf Installation

1. Measure your plants height and map them out for your cabinet interior.
2. Mark desired shelf levels. (For Milsbo, Fabrikor and Blaliden, you can choose for various levels of pre-drilled holes to place your shelve)
3. Secure brackets evenly.
4. Place shelves and check level.

Safety Tips

• Don’t overtighten screws — can crack your plastic brackets, acrylic or glass.
• Test stability before loading with plants.

Styling Your IKEA Greenhouse Shelves

Layering Plants for Height & Depth

Mix tall plants in the back with shorter varieties up front.
