Please cut the rock wool into cubes according to your own needs with a knife before soaking. 2. Please simply soak the rockwool cube briefly (10 sec) in a nutrient solution to adjust its EC value and pH value. Don't squeeze it! 3.

Review: Excellent 1 Inch Rockwool Cubes for Seed Starting and Cloning - I’ve been using the **Halatool 1 Inch Rockwool Cubes (Garden Rock Wool Stonewool Grow Cubes Starter Plugs)** and they have performed really well for both seed starting and plant propagation. These cubes are nicely sized at 1 inch, making them perfect for starting small seeds or rooting cuttings without taking up too much space. The rockwool is consistent in density and holds moisture very well while still providing excellent aeration to the roots. They soak up water quickly and stay evenly moist, which is exactly what young roots need. pH stability has been good after the initial soak and rinse (I always pre-soak them in pH-adjusted water as recommended). What I appreciate most is the quality — the cubes are uniform, don’t crumble easily, and have a clean feel with minimal dust. They fit perfectly in standard seedling trays or net pots and transition smoothly when it’s time to move plants into larger systems like hydroponics, coco, or soil. I’ve had great germination rates with vegetables and herbs, and my clones have rooted quickly and healthily in these Halatool rockwool plugs. If you’re looking for reliable, well-made **1 inch rockwool starter plugs** for gardening, hydroponics, or cloning, these are a solid choice at a good price. They do the job effectively and help give your plants a strong start. Highly recommended! Review: So easy to use! - These cubes are amazing! They fit in my aero garden with a slight push.

I also think the plants will be easy to transplant. I will definitely buy these cube again, ## Features - Value Package Includes: You will get 4 sheets of 1-inch rockwool, a total of 200 pieces of rockwool cubes.
