Who This Is For
- You are switching to shrink-wrapped strips because loose cubes slow down your tray loading and create a mess.
- You are moving to Optiplus drainage because your previous media stayed too soggy and caused root rot issues.
What We Found
- The shrinkwrap keeps the cubes tidy and prevents the outer edges from drying out unevenly while they sit in the tray.
- We noticed roots push through these faster than denser stonewool because the fiber density offers less resistance.
What Users Say
- Large scale operators say the shrink-wrapped strips of fifteen cubes cut their tray loading time by nearly half.
- Growers using these reported fewer issues with root rot after switching to a cube with built-in drainage channels.
Cultiwool 1.5" x 1.5" x 1.5" Cubes w/ Shrinkwrap (2250 Pieces/Case)
Struggling with uneven moisture or slow root development during propagation? The Cultiwool 1.5" x 1.5" x 1.5" Cubes w/ Shrinkwrap provide the professional-grade solution for early-stage growth. These premium rockwool cubes offer an optimized air-to-water ratio, ensuring your seedlings and clones get the oxygen and hydration they need to thrive. If you require larger volumes for transplanting, we recommend the Cultiwool 3" x 3" x 3" Growing Blocks or the Cultiwool 1.5" x 1.5" x 1.5" Cubes without the wrap for different workflow needs.
Each 38mm cube is engineered with Cultiwool's exclusive fiber technology, promoting even nutrient distribution and rapid root penetration. The added shrinkwrap protection helps maintain the shape of the media during high-volume handling and acts as a barrier against light to suppress algae growth. For those starting from the very beginning, these cubes pair perfectly with the Cultiwool 84 Cell Rooting Plug Sheets to create a seamless growth transition.

FAQs
Why are these cubes shrinkwrapped?
The shrinkwrap helps stabilize the cubes during handling and transport. More importantly, it blocks light from hitting the sides of the media, which significantly reduces algae growth.
What is the benefit of the Optiplus drainage?
Optiplus drainage refers to the grooved underside of the cube that allows excess nutrient solution to flow away freely, ensuring the root zone doesn't become waterlogged.
How many cubes come in a single case?
Each case contains 2,250 cubes, organized into 150 strips of 15 cubes each.
Can I use these for both seeds and clones?
Absolutely. The 1.5" size and the Plant Comfort fiber structure make these ideal for starting seeds or rooting cuttings with minimal resistance.
Do I need to stabilize the pH before use?
Yes, it is standard practice to soak rockwool in a pH-adjusted solution (around 5.5) before use to ensure the media is ready for young plants.
