Nutrient Soil Blocks for Vegetable Planting and Seedling Cultivation – 100x20mm 120g

These nutrient soil blocks offer a convenient, mess-free solution for sowing seeds, planting seedlings, and cultivating healthy vegetables. Each compressed disc expands when watered, providing a consistent growing medium with a high water absorption rate of 500% and a pH range of 5.2–5.5 that suits many plant types. Available in multiple particle size specifications, including the 100x20mm size weighing approximately 120g ± 5g, these blocks are packaged loose for easy handling. Ideal for home gardeners and professional growers alike, they eliminate the need for separate potting soil and reduce transplant shock.

Features and Construction

Each nutrient soil block is designed to simplify the process of starting seeds and growing plants. The medium is pre-compressed and expands to its full size upon hydration, offering a stable structure for root development.

Material and Build

Made from nutrient soil, the blocks provide a balanced mix of organic matter and essential nutrients. The pH value of 5.2 to 5.5 creates a slightly acidic environment that supports a wide range of vegetables and ornamental plants. The material is loose in packaging but compresses into a firm block that holds its shape.

Size and Practical Fit

The blocks come in several particle size specifications to suit different seedling stages and plant types. The 100x20mm option weighs 120g ± 5g and offers a larger volume for more developed root systems. Other available sizes include 30x10mm (8g ± 1g), 35x10mm (10g ± 2g), 40x15mm (18g ± 2g), 45x15mm (20g ± 2g), 50x15mm (25g ± 2g), 60x20mm (48g ± 2g), and 70x20mm (60g ± 2g).

Uses and Placement

These nutrient soil blocks are designed for use in sowing, transplanting, and seedling cultivation. They can be placed in seed trays, pots, or directly in garden beds.

Event or Professional Use

Garden centres, nurseries, and horticultural professionals can use these blocks for uniform seed starting and transplanting. The consistent size and weight make them easy to handle in bulk, and the high water absorption helps maintain moisture during germination in controlled environments.

Everyday Home Use

Home gardeners will find these blocks useful for starting vegetable seeds, herbs, and flowers. They reduce the need for multiple bags of potting soil and simplify the process of moving seedlings to larger pots or the ground.
