Cultiwool Starter Macroplug V-Slit (1980/Case)

The Cultiwool Starter Macroplug V-Slit (1980/Case) is a professional round stone wool propagation plug designed for seed starting, rooting cuttings, and high-volume plant propagation. Manufactured in the Netherlands, these macroplugs provide a stable root-zone environment with a balanced air-to-water ratio and a consistent fibre structure.

Each plug features a convenient V-Slit opening, making it especially practical for inserting cuttings while helping maintain good contact between the stem and the growing media. Each case contains 1,980 macroplugs, making this bulk format ideal for commercial greenhouses, nurseries, propagation facilities, indoor growing operations, and other high-volume horticultural applications.

What Is the Cultiwool Starter Macroplug V-Slit Used For?

The Cultiwool Starter Macroplug V-Slit is designed for seed germination, cloning, and rooting plant cuttings.

Its round shape and V-Slit design make it especially useful for propagation workflows where growers need to insert delicate cuttings quickly and consistently without forcing the stem into a small pre-drilled hole.

The plug can be used during the early propagation stage before young plants are transplanted into larger stone wool blocks, slabs, containers, or other growing systems.

Key Benefits

• Professional round stone wool propagation plugs.
• 1,980 macroplugs per case for high-volume production.
• Designed for seed starting, cloning, and rooting cuttings.
• The V-slit opening simplifies placing plant cuttings.
• Helps maintain good contact between the cutting stem and growing media.
• Balanced air-to-water ratio for propagation.
• Consistent fibre structure for uniform moisture management.
• Firm plug construction for easier handling.
• Suitable for integration with larger stone wool blocks and slabs.
• Ideal for commercial greenhouses, nurseries, propagation rooms, and indoor cultivation facilities.

What Is the Advantage of the V-Slit Design?

The V-Slit provides an opening along the side of the macroplug that lets you position a cutting inside the growing media with minimal pressure.

This can be especially helpful when working with delicate stems because the grower does not need to force the cutting into a small pinhole. The slit also makes it easier to visually inspect the cutting and the surrounding rooting zone during propagation.

How Does Cultiwool Stone Wool Support Root Development?

Cultiwool stone wool is engineered to provide a controlled balance between moisture retention and aeration.

The fibre structure holds water while maintaining air space around the developing roots. This provides growers with a stable propagation environment where moisture, nutrients, and oxygen can be managed consistently.

The firm structure of the macroplug also helps it maintain its shape throughout the propagation process.

Ideal Applications

The Cultiwool Starter Macroplug V-Slit (1980/Case) is suitable for:

• Seed germination
• Rooting cuttings
• Cloning
• Commercial propagation
• Greenhouse production

How Do You Use Cultiwool Starter Macroplugs?

Prepare the macroplugs according to your propagation program and place them in a suitable tray or propagation system.

For cuttings, gently open the V-Slit and position the stem inside the plug so it maintains contact with the stone wool. For seeds, place the seed according to the desired propagation method.

Maintain suitable moisture, nutrient concentration, temperature, humidity, and environmental conditions throughout the rooting period.

Once the plant has established a sufficient root system, the macroplug can be transplanted into a larger growing block, slab, container, or other production system.

Can Cultiwool Macroplugs Be Used for Cuttings?

Yes. The V-Slit design is particularly well suited for plant cuttings and clones.

The side opening allows growers to position the cutting with less pressure on the stem while maintaining contact with the moist stone wool substrate.

Can Cultiwool Macroplugs Be Used for Seeds?

Yes. In addition to cuttings and clones, the macroplugs can also be used for seed germination and young plant propagation.

Their uniform structure helps growers maintain consistent propagation conditions across larger batches of plants.

Can the Macroplug Be Transplanted Into a Larger Stone Wool Block?

Yes. Once a healthy root system has developed, the Cultiwool Starter Macroplug can be transferred into a compatible larger stone wool block or another growing system.

This makes the macroplug suitable as the first stage in a multi-stage stone wool production system.

Who Is the Cultiwool Starter Macroplug V-Slit Best For?

The Cultiwool Starter Macroplug V-Slit is particularly well suited to growers who need a consistent propagation substrate for larger quantities of plants.

The 1,980-plug case is ideal for commercial greenhouses, nurseries, propagation facilities, indoor cultivation operations, and professional horticultural producers that regularly root cuttings, germinate seeds, or produce young plants at scale.
