10 Frequently Asked Questions (FAQs)

1. How do I prep the plugs for use?

Soak the tray of plugs in pH-adjusted water (around pH 5.5–5.8) for 10–15 minutes. Let excess water drain before planting.

2. Can I use these plugs for both seeds and clones?

Yes! They're designed for both applications. The pre-drilled hole makes it easy to insert either a seed or a freshly cut clone.

3. Do I need to add nutrients when soaking the plugs?

Optional for seeds. For clones, you may want to soak them in a mild rooting solution or cloning nutrient mix to give your cuttings a boost.

4. Do these plugs fit standard 98-cell trays?

Yes, they're designed specifically for standard 98-count propagation trays, making them easy to integrate into most grow rooms.

5. Are these plugs reusable?

Generally, no. They are intended for one-time use to ensure sterility and avoid cross-contamination between cycles.

6. Can I use these in soil-based systems?

While designed for hydroponics and soilless media, the plugs can be transplanted into soil once roots are established.

7. What are they made from?

Basalt rock, which is melted and spun into fine fibers, forming the stone wool plug. It’s inert and safe for plants.

8. Do they work with domes or humidity trays?

Yes. For clones or seeds, using a humidity dome is ideal for maintaining high moisture levels during early rooting.

9. How long until I see roots?

With proper conditions, clones typically begin rooting within 5–7 days. Seeds will germinate in 2–4 days.

10. Can I automate watering with these?

Yes. The uniform shape and water-holding capacity make them ideal for automated misting or drip irrigation systems.
