Oasis Horticubes Aeromax Multi Seed Top Groove | 1in - 162ct

Fine-Cell Substrate for Uniform Moisture Under Overhead or Subirrigation, 162ct

Overhead watering and subirrigation move water through a propagation substrate in different ways, and a substrate built for only one method can leave the other running unevenly. Oasis Horticubes Aeromax Multi Seed Top Groove uses a modified cell structure and a fine-cell design engineered to hold moisture uniformly regardless of which irrigation method is used.

This 1-inch, 162ct sheet uses a top groove format sized for multi-seed sowing, with density and drainage properties tuned to that fine-cell design.

Key Features & Benefits

• Modified Cell Structure — engineered chemistry supports faster, stronger root growth than a standard substrate.
• Fine-Cell Design — provides uniform moisture whether watered from overhead or by subirrigation.
• Top Groove Format — sized for multi-seed sowing across the sheet.
• 1-Inch, 162ct Sheet — sized for standard 1020 propagation trays.

Who Should Use This Substrate

This substrate fits professional hydroponic growers sowing seed at scale who need consistent moisture across the sheet regardless of whether their operation waters from overhead or through subirrigation.

About Smithers-Oasis

Smithers-Oasis, founded in 1954, develops its Horticubes Aeromax line through its Oasis Grower Solutions division, which runs an R&D facility in Kent, Ohio with more than 55 years of experience across 19-plus countries. The Aeromax substrate chemistry is engineered specifically for professional hydroponic propagation rather than general nursery use.

Frequently Asked Questions

What does the modified cell structure do?

It changes the substrate's internal chemistry and structure to support faster, stronger root growth than a standard propagation substrate. The fine-cell design that comes with it is also what gives the sheet its uniform moisture behavior.

How do I water this substrate?

It's built to perform under either overhead irrigation or subirrigation, so growers don't need to change their existing watering method to use it. Keep the sheet consistently moist through germination and early root development regardless of method.

What does the top groove format mean?

The top groove is a molded channel pattern across the sheet that's sized for sowing multiple seeds per sheet in an organized layout. It's built for multi-seed propagation rather than single, widely-spaced sowing.

How does this differ from OASIS HORTICUBES Aeromax 2.0?

This Multi Seed Top Groove format uses a modified cell structure focused on uniform moisture across overhead and subirrigation setups. Aeromax 2.0 is a separate substrate line engineered more specifically around airflow and oxygen delivery to the root zone.
