Overview

Halatool 1.2-inch Rockwool Cubes are a ready-to-use growing medium designed for hydroponics, seed starting, and plant propagation. This value pack includes 2 sheets totaling 72 cubes, crafted to support gentle handling, consistent moisture delivery, and reliable early-stage growth.

What’s Included

  • 2 sheets of 1.2-inch rockwool cubes
  • Total of 72 starter plugs for batch propagation

Natural Material and Texture

Made from high-quality basalt rock and processed to yield a soft, even texture. The medium offers strong water absorption and notable air permeability, helping roots access moisture while staying oxygen-rich for healthy initial development.

How to Use

  • Cut the rockwool into the needed sizes with a sharp knife.
  • Briefly soak the cubes (about 10 seconds) in a nutrient solution to adjust EC and pH.
  • Keep moisture balanced and provide appropriate light and temperature for germination.
  • Transplant when robust roots approach 0.5 to 1 inch, into nets pots, soil, or hydroponic setups.

Tip: The optimum pH for many seeds is around 5.5; adjust EC and pH to match your seed requirements as you proceed.

Transplant and Care

Rockwool grow cubes hold moisture well and offer easy planting holes, making transplanting straightforward. They maintain root systems during transfer and can stay in place as you move seedlings into larger containers or different systems.

Ideal For

Perfect for hobbyists and commercial growers who favor a soil-free start for seedling kits, cuttings, and clones. Compatible with hydroponic systems, rooting stations, and cloning setups, these plugs simplify early-stage cultivation.

Benefits at a Glance

  • Value and convenience with a 72-piece pack in a 2-sheet design
  • Natural basalt-based material with soft texture and strong moisture handling
  • Good air flow to roots supports healthy establishment
  • Easy to prepare and transplant without disintegration
  • Versatile for hydroponics, seed starting, rooting, cloning, and propagation
