The Milsbo gets most of the attention, but the IKEA Rudsta quietly makes one of the best starter greenhouse cabinets out there. It’s shorter, it has glass on the sides as well as the front, and its dark anthracite frame makes plants look like they’re sitting in a little conservatory. If you’ve been eyeing a cabinet build but don’t have the wall (or the nerve) for a six-foot Milsbo, the Rudsta is a very friendly place to begin.

We’ve already covered the tall and wide Milsbo builds, so this guide is about what makes the Rudsta different: where it shines, where it leaks, and exactly how to set one up so your tropicals actually thrive in it.

Why Choose the Rudsta?

Most of the plants we fall for (velvet Anthuriums, jewel orchids, small Alocasia, Begonias, Marantas) come from forest floors where humidity sits somewhere in the 60–80% range. A typical living room runs closer to 30–50%, and it drops further once the heat comes on in winter. A glass cabinet closes that gap for a handful of plants without turning your whole home into a swamp.

Here’s why the Rudsta in particular is worth a look:

  • It’s a manageable size. The Rudsta is noticeably shorter than the tall Milsbo, so you need fewer lights, fewer fans and less sealing to get it dialed in. It’s a great first build.
  • Glass on three sides. More ambient room light reaches your plants, and you can see the whole collection from the side. It reads as furniture rather than equipment.
  • It’s a steel frame. Magnets stick, which makes mounting lights, fans and sensors much easier than in a wooden cabinet.
  • The top is usable space. A trailing Hoya or a pothos on top softens the whole look and makes good use of the warmth that rises off the lights.

The tradeoffs are worth knowing up front. Less height means you’re growing smaller plants (or young ones), and glass sides lose a little more heat and humidity than solid panels do. The door gaps are also generous straight out of the box. All of this is fixable, and we’ll walk through it.

Before you buy: IKEA changes sizes, finishes and availability by region, so check the current Rudsta listing on IKEA’s site for exact dimensions and measure your space before you order.

Which Plants Love a Rudsta?

Because the Rudsta is compact, it suits plants that stay small or grow slowly. Our favorites for this cabinet:

  • Jewel orchids (Ludisia, Macodes): they adore stable humidity and gentle light.
  • Velvet Anthuriums while they’re young, like A. clarinervium and A. crystallinum.
  • Small Alocasia such as Black Velvet, Dragon Scale and Silver Dragon.
  • Begonias, especially the rex and maculata types.
  • Marantas, Calatheas and Fittonia, which crisp up fast in dry air.
  • Propagation projects. A shelf of cuttings in a humid cabinet roots faster than anywhere else in the house.

Skip anything that wants dry air or blazing sun. Succulents, cacti and most herbs will sulk in there.

🧰 The Full Materials List

The cabinet & shelving
– IKEA Rudsta glass-door cabinet, ordered directly from IKEA
– Acrylic shelves to replace the glass shelves, so light passes through to lower levels and air moves more freely
– Acrylic plant risers to lift small plants closer to the lights

Light
– Full-spectrum LED grow light bars, one per shelf. Linkable bars keep the wiring tidy.
– Strong magnetic hooks to hold lights to the steel frame (the clips that come with most light bars aren’t strong enough)

Humidity & airflow
– USB clip fans for gentle cross-ventilation. This is your mold insurance.
– Small cool-mist humidifier, optional and only needed if sealing alone doesn’t hold your target
– Weather stripping for the door edges and the center gap
– Clear silicone door seal strip for a near-invisible seal on the glass edges
– Digital hygrometer so you always know your real numbers

Automation & cords
– Smart plug to run lights and fans on a schedule
– Surge protector power strip to power everything from one spot
– Adhesive cord clips to keep cables flat against the frame

Growing basics
– Clear nursery pots so you can watch roots and moisture
– Chunky aroid potting mix, which stays airy in high humidity instead of turning to mush

🔨 Step-by-Step Setup

  1. Assemble the cabinet on level ground. Follow IKEA’s instructions, and check it’s level before you load it. A wobbly glass cabinet full of wet pots is not a vibe. If your floor slopes, use the adjustable feet or a shim.
  2. Plan your cord route first. The Rudsta has small gaps at the back and base. Route your cords through an existing gap rather than drilling, and you’ll keep the frame intact. Run every cable to one corner so it’s easy to hide.
  3. Swap in acrylic shelves. Peel off the protective film, set them on the existing shelf supports, and space them so each level has at least a few inches of headroom above the tallest plant. Two shelves plus the floor is a comfortable layout for most collections.
  4. Mount the lights. Attach one light bar to the underside of each shelf (and one at the top for the upper level) using magnetic hooks or mounting tape. Keep them toward the front edge so light falls on the leaves, not the back wall.
  5. Add airflow. Clip a USB fan low on one side, angled to push air across the cabinet. You want a gentle rustle in the leaves, never a gale.
  6. Seal it. Run weather stripping along the door frames and the center gap where the doors meet. Leave a small unsealed gap somewhere near the top so the cabinet can breathe. Fully airtight plus wet soil equals mold.
  7. Set up monitoring and automation. Place the hygrometer at mid-height, away from the humidifier mist. Put lights on the smart plug for 10–12 hours a day and fans on a schedule of your choice (many growers run them continuously on low).
  8. Let it settle before adding plants. Run the cabinet empty for two or three days and watch your numbers. Adjust the seal, add or remove the humidifier, then move your plants in.

Dialing in Humidity on the Rudsta

The Rudsta’s glass sides mean it reacts more to the room around it than a solid-sided cabinet does. A few things that help:

  • Aim for 60–75% for most tropicals. Higher than that, without good airflow, invites fungus and soft rot.
  • Seal first, humidify second. Many Rudsta growers find that weather stripping plus a tray of damp LECA or a few open water dishes holds 60%+ with no humidifier at all.
  • Watch the season. Expect humidity to dip when your heating kicks on in winter. That’s when the small humidifier earns its spot.
  • Wipe the glass. Constant fogging means there’s too much moisture and not enough air movement. A little condensation in the morning is fine; streaming droplets all day isn’t.

Common Problems (and Fixes)

  • Mold on the soil surface: more airflow, less water, and a top layer of chunky bark or LECA. Remove anything fuzzy right away.
  • Leggy, stretching plants: the lights are too far away or running too short. Move bars closer or add an hour.
  • Crispy leaf edges despite the cabinet: check your hygrometer placement. If it’s right next to the humidifier, it’s reading high and the far corner may be dry.
  • Fungus gnats: they love humid cabinets. Let the top inch of soil dry between waterings and use sticky traps to catch the adults.

Frequently Asked Questions

Is the Rudsta better than the Milsbo? Neither is “better.” The Rudsta is smaller and easier to set up, and it’s great for a first build or a compact collection. The Milsbo gives you more height and shelf space for bigger plants.

Do I really need fans? Yes. Humid, still air is exactly what mold wants. A small USB fan costs very little and prevents most problems.

Can I put the Rudsta near a window? You can, but keep it out of direct afternoon sun. Glass cabinets heat up fast, and a sunny window can cook your plants. Grow lights give you steadier, more controllable light.

How long should the lights run? Ten to twelve hours a day suits most tropical foliage plants. Put them on a timer so it happens whether you remember or not.

Do I need a humidifier? Not always. Seal the cabinet properly and test for a few days first. Add one only if you can’t hold your target.

Quick-Start Checklist

The Rudsta proves you don’t need a giant cabinet to give your fussiest plants the rainforest they’ve been asking for. Start small, watch your numbers, and let your collection grow into it. Happy growing, from all of us at BloomBabe. 🌿🪟
