CANTO Slatestone Size Comparison

|---|---|---|---|---|
| Length x Width | 11.8" x 11.8" | 11.8" x 11.8" | 15.7" x 15.7" | 15.7" x 15.7" |

Which CANTO Slatestone Should You Choose?
- Low 30: A compact cube-shaped planter for smaller houseplants, patio flowers, and decorative arrangements.
- High 30: Adds height and style to entryways, offices, and narrow spaces without needing additional potting soil.
- Low 40: Offers generous root space for medium-sized foliage plants, flowering arrangements, and patio greenery.
- High 40: Creates a striking architectural display with greater planting capacity, ideal for larger indoor plants and prominent entryway arrangements.
Best Plants for CANTO Slatestone
The square shape and generous planting area make CANTO Slatestone an excellent option for a variety of indoor and outdoor plants. Popular choices include:
- Houseplants: Monstera, Philodendron, Ficus, and Dracaena in appropriately sized varieties.
- Low-Maintenance Foliage: Snake plants and ZZ plants, with watering adjusted to their preference for drier conditions.
- Outdoor Flowers: Geraniums, begonias, petunias, and compact flowering annuals.
- Ornamental Grasses: Compact sedges and other smaller decorative grasses.
- Seasonal Arrangements: Mixed foliage and flowers for patios, entryways, and outdoor living spaces.
Planting Tip: The 30 models have approximately 8 inches of planting depth, while the 40 models provide approximately 10 inches. Select plants based on their root size and mature growth rather than the decorative height of the planter. Group plants with similar light and water needs.
Convenient Removable Planting Liner
The removable planting liner features retractable carrying handles, making it easy to prepare arrangements on a potting table before lowering them into the decorative planter. This is especially convenient with the tall High models, allowing you to plant at a comfortable working height.
Helpful Tip: The matching liner dimensions of Low and High models make it easier to change decorative styles without disturbing established plants, provided the liner size is the same.
How the Self-Watering System Works
- Prepare Your Planter: Add the included LECHUZA-PON drainage substrate and an appropriate growing medium according to the manufacturer's planting instructions.
- Add Your Plant: Position the plant in the removable liner and gently fill around the roots.
- Establish the Roots: Water from above for approximately 2-3 weeks, checking moisture regularly while roots establish.
- Begin Reservoir Watering: After establishment, fill the reservoir halfway initially. If the water level drops over the next few days, follow LECHUZA's instructions for filling to the maximum level.
- Allow a Dry Phase: Monitor the water level indicator and allow an appropriate dry period before refilling, based on your plant's needs.
Outdoor Use: Remove the drainage screw to allow excess rainwater to escape. Watering frequency depends on plant type, sunlight, temperature, and weather.
Complete Your Planter With LECHUZA-PON
Every CANTO Slatestone planter includes LECHUZA-PON for the required drainage layer. If you'd like to use a mineral growing medium throughout the planting area, consider purchasing additional LECHUZA-PON Mineral Potting Mix . Its natural mineral blend supports excellent drainage, healthy root aeration, and balanced moisture retention.
Growing palms or Mediterranean plants? LECHUZA PALMPON is another option formulated specifically for those plants. Standard LECHUZA-PON remains our general-purpose recommendation.
Shop LECHUZA-PON →Additional substrate sold separately. The planter already includes the mineral material needed for its drainage layer. Appropriate conventional potting soil can also be used.
