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.

    good for puppys young dogs, handle is separate, locking carabiners on both ends
    Color: Orange, Size: 30FT
    This is a good sturdy leash but probably wouldn't stand up to a conscientious chewer if your dogo has that bad habit. I like this one because the handle is separate so it can be used both as a tie out lead and as a regular lead. I also like the "locking" carabiners that should not open accidentally. I bought the thirty foot version because my new puppy loves to go outside then refuse to come back in or let me catch him when I need him to come inside (not catching me silly Hooman). When he's bigger I won't be so concerned about him being outside alone but since I'm in a sort of rural area, we have the occasional fox and hawk around when the sun goes down. Not too much to worry about in the way of pests but every puppy parent has an obligation to protect their young'un till they gain some wisdom. I have stairs in the back of the house, the way this is made I can attach it to the banister easily so I don't even need one of those tie stakes that bury in the ground. The price wasn't bad, the hardware looks sturdy and should last awhile. I just also bought the fifteen foot version, same quality as the thirty foot product I like that the handle is separate so it can be used as a tie down or a leash easily. My only big wish would perhaps be some more color choices, the orange is nice for visibility a yellow would be nice and then maybe some other colors like red/purple would be good as well. The thickness of the rope means that it doesn't "easily" get tangled into a giant knot. I leave the back door open and puppers can go in and out as he likes but he also sometimes runs around in the living room and thus far haven't had any large tangles to unwrap. He did manage to get the leash caught around a piece of tree branch that was on the ground (and complained loudly) but that was only because the branch was too heavy for him to drag the lead off of by himself. These leads are worth the money, I will likely buy a couple more to keep in the vehicle and other locations besides home.

    My Go-To Leash for Outdoor Fun and Training with My Lab Puppy
    Color: Orange, Size: 15FT
    The Joytale Long Leash, specifically the 15-foot model, is an exceptional product that has seamlessly integrated into the daily activities of our black lab puppy. Purchasing this leash has proven to be a decision that greatly benefits both our family and our energetic puppy, especially during our adventures in the backyard and while hiking. The vibrant orange color of the leash stands out, which is not just visually appealing but also significantly enhances safety by ensuring the leash remains highly visible. This feature is particularly useful in varied terrains and during low-light conditions, providing peace of mind that our puppy is always within sight and safe. The leash's design, featuring a removable padded handle, has been a game-changer for comfort. The padding ensures that our hands are protected from any strain or discomfort, even during those longer hikes or when our puppy gets a bit too excited and pulls. This thoughtful inclusion has made our outdoor adventures much more enjoyable, allowing us to focus on the fun and bonding with our puppy rather than any potential discomfort. Equally impressive is the double hook mechanism that the Joytale Long Leash boasts. This feature has instilled a great sense of security in us, knowing that the leash is securely attached to our puppy’s collar or harness. It's especially reassuring during hikes in more challenging terrains where a secure leash attachment is crucial for our puppy's safety. The 15-foot length of the leash has been perfect for our needs. It provides ample space for our black lab puppy to explore and play, whether we're in the backyard or adventuring through hiking trails. This length strikes a perfect balance, offering enough freedom for him to explore while still under our control, facilitating a safe and enjoyable environment for him to learn and grow. Durability is another aspect where the Joytale Long Leash shines. It has stood up to the rigorous daily activities of our puppy, showing no signs of wear and tear. This durability is not only a testament to the quality of the materials used but also to the thoughtful design that has gone into making this leash a reliable accessory for pet owners.

    Great long leash, would buy again
    Color: Blue, Size: 30FT
    Well-made leash, perfect for recall training and other situations where the dog needs a bit of space to roam without getting into trouble. Seems to be comfortable for the dog, as it is not inhibiting him from running around and playing. I bought the 30 foot length 3/8” diameter version. Light weight, good value for the price. Best feature is the locking carabiner, because my rescue pup “moonlights” as an escape artist. 🤣🤣
