Grandio Greenhouse Trellis Kits

Grandio Greenhouse Trellis Kit

The Grandio Greenhouse Trellis Kit gives climbing plants — tomatoes, cucumbers, beans, peas, and other vining crops — the vertical support they need to grow taller, healthier, and more productively inside your Grandio greenhouse. At $59, it's a complete kit that transforms unused vertical space into a thriving growing area while improving airflow and making harvesting easier.

What's Included in the Trellis Kit?

• 6 heavy-duty trellising holders
• 6 spools of strong trellising string
• Large assortment of connectors and fasteners — for quick, secure plant attachment

What Plants Can You Trellis in a Grandio Greenhouse?

The kit is designed for any climbing or vining crop, including:

• Tomatoes (indeterminate varieties especially benefit from vertical support)
• Cucumbers
• Beans and peas
• Squash and melons (with additional support for heavy fruit)
• Peppers and other tall plants that benefit from staking
• Flowering vines and climbing ornamentals

Why Use a Trellis in a Greenhouse?

Vertical growing in a greenhouse delivers several key benefits over ground-level growing:

• More plants in less space — vertical growth frees up bench and floor space for additional crops
• Better airflow — plants off the ground have improved air circulation, reducing the risk of fungal disease and mold
• Easier harvesting — fruit and vegetables at eye level are faster and easier to pick
• Healthier plants — upright growth reduces contact with soil and standing water, lowering disease pressure
• More light exposure — vertical canopies intercept more light than sprawling ground-level plants

Is This Trellis Kit Compatible with All Grandio Greenhouses?

The Grandio Trellis Kit is designed for use inside Grandio greenhouses. The trellising holders are built to work with the Grandio greenhouse frame system. If you have questions about compatibility with your specific Grandio model, contact the Grandio team before ordering.

How Is the Trellis Kit Installed?

The kit is designed for easy DIY installation. The holders attach to the greenhouse frame, and the trellising string runs between them to create vertical support lines for your plants. Connectors and fasteners are included for securing plants to the string as they grow. No specialized tools are required.
