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 need to find a better way to ship it
    Style: 1 gal
    What was left in the bottle worked great. However, the cap was off of the jug when I opened the package. Ididn't have enough for the other tires.

    This stuff just works! Very impressed. If you have a slow leak, get this!
    Size: 20oz
    This is the second time I've bought this product. I bought one initially to test it out and I was very impressed! I had put some used tires on some used rims for my side by side and I had a couple of them leaking slowly from the side of the rim. I put this stuff in, following the directions and have no more leaks! It's been about a week with the first one, and zero loss in air pressure. I took my side by side out on the trails and thrashed around a bit, still no leaks! This stuff is legit! It comes with a valve removal tool and red valve stem covers to show you which tires you've added this too. Very easy to use, no issues whatsoever. Saves you money having to take your tires somewhere to have them look at them.

    This stuff worked better than I thought it would
    Size: 40oz
    As my title says, this stuff worked better than I thought it would. In fact it worked so well today I will be ordering more. I say today because how can you tell if something like this is actually working... never getting a flat for years? In other words, if it fixes a flat before your eyes it works, otherwise you really don't know. See I had a lawn mower tractor that developed a real bad tire leak a couple of days ago. The way it happened was I cut a Russian Olive tree down, if you know what one of these trees are like, you already know why I got such a bad leak. These darn things have thorns that can get to be almost as big around as a pencil, and are just as sharp as a needle. Moreover, these spikes as I call them, can get to be 3" to 4" long. In short, if you run over one you will have a flat tire, period. That is unless you have this stuff inside the tire already. To make matters worse, if you run over a branch from this tree, you won't only get one or two thorns/spikes stuck in your tire, because as you drive the branch bends easily (only the spike are ridged), so before you know it you will end up with a half dozen of these spikes all the way around your tire, as if the whole tire has a new tread made up of a Russian Olive tree branch. Trust me on this, it will happen just like this. After pulling a half dozen 2" to 4" inch spikes out of the tire, I knew if I took it to a shop they would require me to put a tube in. With this inflation that isn't supposed to be an inflation going on, I'm sure it has made tire tubes today cost almost as much as the whole tire cost me just a couple of years ago. So I thought I'd put this product to a real test... I already have some in my John Deere 2305 tractor. Honestly, it shocked me how quick it worked. It worked so fast I didn't even need to add anymore air to the tire, because all the holes were shut. Pretty amazing stuff if you ask me! I followed the directions, they were easy to follow and the process was easy too. I removed the valve stem, put in 5 ounces of the solution, then put the valve stem back in, aired up the tire and it was instantly fixed... amazing, especially considering why the tire was flat... I should have taken a pic of the spikes. I did roll the tire around a bit, then mounted the tire back on the tractor and went right over and mowed my elderly neighbors lawn, so it got plenty of rotation time. That was about 4 hours ago and the tire is still rock hard. Like I said, I'm ordering more because after seeing this everything we have that runs slow will have this stuff in the tires! Oh, one other thing. The fix-it flat stuff in a spray can, DO NOT USE IT for applications like this! Because that stuff if left inside will actually glue your tire to the rim. Tires have been ruined trying to pry them away from the rim after putting in fix-a-flat, or whatever that crap is called. Sadly this "TireJect" is not recommended for high speed travel, it will through your tire out of balance. So use the fix-flat stuff in an emergency, carry one in your car just in case. Just make sure once you get the tire fixed wash the tire out real good before remounting it. I have never written such a long review in my life, but if you got through it I hope it helped. It's not often a product lives up to it's claims today, but this one in my opinion surpasses it, so I felt the need to say something. Besides, the warning about the Russian Olive tree just may save someone a lot of frustrations.
