Who This Is For

  • Cultivators moving from starter plugs who need a final substrate that supports vigorous late-stage root development.
  • Commercial operations facing uneven nutrient distribution across long benches due to poor media homogeneity.

What We Found

  • The vertical fiber orientation prevents the bottom of the slab from becoming waterlogged while the top stays dry.
  • The 3-inch slab height provides enough depth for substantial root expansion without excessive vertical space needs.

What Users Say

  • Commercial growers report that the uniform water distribution helps them maintain a more precise irrigation schedule.
  • Greenhouse managers say the standardized slab size allows them to maximize bench space without overcrowding crops.

FAQs

What are Cultiwool Mini Slabs used for?+

They are designed as a final-stage growing medium for hydroponic cultivation. They provide the ideal substrate volume for mature plants after they have been started in smaller plugs or cubes, like the Cultiwool 1.5" Cubes.

How do I prepare the slabs before use?+

Before use, you should fully saturate the slabs with a pH-adjusted nutrient solution. Typically, a pH between 5.5 and 6.0 is recommended. Allow them to drain completely before transplanting your crop.

What is the benefit of vertical fiber orientation?+

The vertical fiber structure promotes optimal water and nutrient distribution throughout the entire slab. This encourages roots to grow downwards, creating a stronger, healthier root system and preventing dry spots.

Can I use these slabs with any hydroponic system?+

Yes, these mini slabs are versatile and compatible with various hydroponic systems, including drip irrigation, ebb and flow, and deep water culture (DWC) setups. They are a staple product in the Cultiwool lineup for their adaptability.

What size growing block should I use before transplanting to this slab?+

These slabs are compatible with a range of starter media. For a seamless transition, we recommend using blocks like the Cultiwool 4" x 4" x 4" Growing Blocks, which fit perfectly onto the slab surface.

Are the slabs sterile?+

Yes, each slab is fully sealed in its own wrapping to maintain sterility and protect it from contaminants and algae growth until you are ready to use it.
