Why Designers Choose the Seeley Cube

The Seeley Cube is the foundational choice for anyone who appreciates clean, minimalist geometry. If you have ever seen a standard plastic planter warp or fade after a single season, you will appreciate the industrial-grade difference here. It is designed to be a permanent, design-forward extension of your architecture.

In professional settings, these are most often used to create a "ceremony of arrival" at entryways or arranged in a rhythmic series to create a "living wall." Because the lines are so crisp and the matte finish so refined, the Seeley Cube defines space—like an open-plan office or a sprawling patio—without adding visual clutter. It anchors the environment, allowing your greenery to take center stage.

The Science: Why Steel-Reinforcement Matters for Large Planters

Most large planters suffer from "bellying"—a phenomenon where the sides bulge outward once filled with heavy, wet soil. This ruins the architectural silhouette. To prevent this, NMN Designs integrates internal steel reinforcement into our 20", 24", and 30" models.

This engineering ensures that even when housing a heavy, mature tree, the walls remain perfectly plumb and vertical. Combined with our commercial-grade fiberglass, you get a vessel that handles extreme thermal expansion (from scorching summers to sub-zero winters) without the cracking or brittleness found in standard resin or plastic pots.


Engineered for Performance: Indoor and Outdoor Versatility

The Seeley Cube transitions effortlessly between environments. For interior use in a foyer or gallery, keep the rubber plugs inserted for a watertight seal. For outdoor installations on a deck or patio, simply remove the plugs to ensure vital drainage and oxygen for the root zone.

Recommended Tree and Plant Pairings by Size:

  • 14" Cube (Medium): Ideal for architectural foliage and "tree-like" indoor plants. Best for Snake Plant, ZZ Plants, or a Spider Plant. Perfect for office corners or flanking a residential console table. Outdoor - Ornametal Grasses, Small Plants.

  • 20" / 24" Cube (Large and Extra Large): The perfect size for entryway ceremony and ornamental trees. Ideas include Evergreens and Boxwood Topiaries, Ornamental Grasses, Olive Trees, or Fiddle Leaf Figs. For a vertical architectural look, Sky Pencil Hollies are excellent.

  • 30" Cube (XXL -Extra-Large): Designed for specimen trees and high-impact privacy. This volume is required for larger trees such as Japanese Maples, Dwarf Citrus (Lemon/Lime), or Serviceberry. To create a privacy screen, plant a series of Emerald Green Arborvitae or Tall Ornamental Grasses.


Pro-Tips for the Best Results

  • High-Wind Stability: For exposed roof decks or coastal balconies, add 3 inches of heavy gravel at the base before adding soil. This lowers the center of gravity, ensuring your privacy screen stays upright during heavy gusts.

  • Thermal Protection: While the fiberglass is frost-proof, using an insulated liner inside the planter in extreme northern climates can help protect the root balls of perennial trees, ensuring they return season after season.

    They keep coming back for more ..........
    Size: 64 Fl Oz (Pack of 1), Style: 64 oz Ready To Use
    I've only been using this food for two weeks, but the hummingbirds love it so far. From what I've read, they are attracted to the color of the feeder more so than the smell of the nectar / food itself. With the amount of work that hummingbirds have to go through just to find enough food to survive, I figure it is worth the extra cost of this food compared to making plain sugar water that does not have the added minerals and electrolytes that this feed has to mimic real nectar.

    Very good ... but beware.
    Size: 64 Fl Oz (Pack of 1), Style: 64 oz Ready To Use
    First of all I just want to point out all of the reviews from people who claim that the bottle arrived damaged or open and in some cases ruined the other products shipped in the same box. Amazon will not issue a refund for that, which is absurd. My bottle arrived in good shape although the top was loose - not a big deal. The formula itself I find to be the best out there. I used to buy Pennington, which until this year was a deep red, now it is a light orange. The hummers will not stomach it. This product is better than the older version of the other brand. Taking one star off for all of those people who got a damaged bottle that would not be refunded.

    Quickly accepted by our local hummingbirds.
    Size: 64 Fl Oz (Pack of 1), Style: 64 oz Ready To Use
    I used this in a red hanging hummingbird feeder on a second-floor shaded balcony. The feeder had only been up a short time, and the nectar was accepted quickly. I observed hummingbirds visiting, perching, and drinking from the active lower tiers, so the product clearly did not discourage feeding. What I like most is the convenience. It is ready to pour, clear, and does not require mixing sugar and water. I also appreciate that it is not dyed red. The feeder itself provides enough red visual attraction, so colored liquid is not necessary. For a small balcony feeder, I only needed to fill the reservoirs about halfway, which helped keep the nectar fresh and reduced waste. A few practical notes: I still treat this like any hummingbird nectar and replace it regularly rather than letting it sit for many days. Even in shaded, mild weather, I would rather keep the feeder clean and fresh. The bottle should also be stored properly after opening. Overall, this is a good option if you want a simple ready-to-use nectar without mixing your own. Homemade sugar water is cheaper, but this is convenient, clean-looking, and in my case the hummingbirds used it. I would recommend it for someone who wants an easy pour-and-fill option, especially for a smaller feeder or balcony setup.

    Hummingbirds love it… ants do too 🐦🐜
    Size: 64 Fl Oz (Pack of 1), Style: 64 oz Ready To Use
    This nectar definitely does what it’s supposed to do — the hummingbirds found it fast and keep coming back, which is exactly what I wanted. It’s easy to use and convenient compared to mixing your own. The only downside is that ants seem to love it just as much as the birds. If you’re using this, I’d definitely recommend pairing it with an ant moat or being mindful of where you hang your feeder. Overall, it works great and brings in plenty of hummingbirds — just be prepared to outsmart a few tiny freeloaders along the way.
