Both are D-shaped moss poles, which is the best system when it comes to moisture retention and long-term support for climbing plants.

However, while the classic moss poles closes the D-shape on the back and offers multiple locking positions, allowing for depth adjustment, the front-opening moss pole closes at the front with a single locking position and is only available in a crystal-clear version.

The classic moss pole is ideal if you want a permanent support for your plant, especially if you plan to stack multiple extensions over time and take it easy on maintainance. It's a great option for beginners or those who prefer a more passive plant care routine.

The front-opening moss pole is better suited for plant parents who like to take cuttings, rearrange setups, or eventually size up to a larger moss pole. It allows for easier access and plant removal.

In short: the classic is better for stable, long-term use, while the front-opening is great for flexibility and active plant care.

Both are perfect solutions to help your climbing plants thrive.
