Halatool 1 Inch Rockwool Cubes Starter Plugs for Hydroponics - 200 Pcs (4 Sheets)

Halatool 1 Inch Rockwool Cubes for Seed Starting and Cloning

Introduce seedlings and cuttings to a reliable starter medium designed for hydroponics and soilless cultivation. This Halatool pack features 4 sheets totaling 200 rockwool cubes. The material comes from basalt rock, processed to a soft, uniform texture that traps moisture while allowing air to reach developing roots.

Expect consistent germination and healthy root growth thanks to strong water absorption and good air permeability. When used correctly, these plugs help seeds or cuttings form robust roots before transplanting into net pots, soil, or hydroponic systems.

Key advantages you can rely on

• Value package includes 4 sheets for a total of 200 cubes, ideal for larger projects or frequent starts.
• High quality material with soft texture, balanced water absorption, and ample aeration to support growing roots.
• Simple prep: cut to desired size, then soak briefly in a nutrient solution to adjust EC and pH (target about 5.5).
• Easy transplanting: cubes hold moisture and maintain integrity, enabling smooth transfer to various containers once roots appear.
• Wide applicability: suitable for hydroponics, rooting, plant propagation, cloning, and other soilless cultivation setups.

Practical usage tips: maintain consistent moisture, light, and temperature for germination. When the root system penetrates the cube by about 0.5 to 1 inch, transplant into a suitable container and continue to monitor EC and pH as your plants grow. This starter plug is designed for both home gardeners and commercial growers seeking a straightforward propagation medium.
