Yes. Shelving is designed to fit the width and frame style of each Riga series (‘S’, Standard, Black, or XL). Always choose shelves that match your exact greenhouse model for proper fit and support.

Upper shelves typically hang from the frame or roof area and are ideal for lighter plants, seedlings, or supplies. Lower shelves sit closer to the ground or mid-level and can support heavier trays and larger plants.

Many Riga shelves use polycarbonate inserts instead of solid surfaces. This allows more light to reach plants on lower levels and reduces heavy shading inside the greenhouse.

Yes. Most shelving systems can be added after the main structure is built. Following the model-specific instructions ensures secure attachment to the aluminum frame.

Weight capacity varies by shelf type and model. Upper hanging shelves are generally intended for lighter loads, while lower shelves can support more weight. Avoid overloading and distribute items evenly.

Not necessarily. Many growers start with one level and add more later. Using both maximizes vertical space and creates a more productive, organized growing environment.
