PIONEERS IN PROPAGATION MEDIA

OASIS AeroSubstrates provide precision hydroponic growers with real-world solutions specific to their crops, climates and growing systems.

Aerosubstrates: Differentiating AeroMax™ and AeroSelect™

OASIS® AeroSubstrates are engineered foam substrates designed for precision hydroponic farming in controlled environments. The product family includes two main substrate types:

  • OASIS® AeroMax™
  • OASIS® AeroSelect™

Both are input-responsive, food-safe, and optimized for specific climates, crops, and water requirements.

Key Differences

AeroMax™ Substrates

  • Introduced: 2021
  • Climate Suitability: Temperate, higher-latitude climates
  • Temperature Range: Mild to moderate
  • Water Demand: Lower
  • Crop Suitability: All leafy greens and microgreens except spinach
  • Physical Properties:
    • Total Porosity: 95–99%
    • Air Porosity: 10–15%
    • Water Holding Capacity: 80–85%
    • pH: 5.0–5.8
    • EC: 0.2–0.4 mS/cm
    • Bulk Density: 12–16 kg/m³
    • Initial Moisture Content: 0%
  • Special Features: High air-filled porosity and drainage, rapid nutrient refreshment, helps prevent algae growth.

AeroSelect™ Substrates

  • Introduced: Early 2024
  • Climate Suitability: Lower-latitude, tropical climates
  • Temperature Range: Warmer
  • Water Demand: Higher
  • Crop Suitability: All leafy greens and microgreens including spinach
  • Physical Properties:
    • Total Porosity: 90–95%
    • Air Porosity: 5–10%
    • Water Holding Capacity: 85–90%
    • pH: 5.0–5.8
    • EC: 0.2–0.4 mS/cm
    • Bulk Density: 12–16 kg/m³
    • Initial Moisture Content: 0%
  • Special Features: Developed for higher water-holding capacity in response to grower requests.

Additional Notes

  • Both substrates are available in multiple configurations, including pre-dibbled and undibbled sheets, and automation-ready singulated plug trays.

RhizoPlug

OASIS® RhizoPlug™ Tray: Propagating Innovation

OASIS® RhizoPlug™ Tray is a next-generation, automation-ready propagation media engineered for fast, profuse rooting and vigorous transplant growth. Developed for precision propagation of vegetative cuttings, its singulated foam substrate and pre-dibbled plugs ensure easy, damage-free insertion and optimal contact for all stem sizes.

Growers benefit from up to 20% faster rooting, extraction, and transplanting compared to traditional media, along with rapid hydration, reduced disease risk, and consistent air-to-water ratios for uniform, high-quality young plants. Clean, inert, and pest- and pathogen-free, RhizoPlug™ is available pre-loaded in 72, 105, and 128 count trays, making it ideal for floriculture crops, culinary herbs, tropicals, industrial hemp, and even fragile-stemmed varieties—offering flexibility, efficiency, and a cleaner propagation environment.

AeroSelect Microgreen Sheet

High-value microgreens are prized by chefs, gourmets, and health-focused consumers for their intense flavor and nutrient density. These young greens are easy to grow indoors or in vertical farms, offering rapid turnover and minimal inputs. Popular varieties include pea, radish, broccoli, mustard, and sunflower.

With Oasis Grower Solutions’ climate-optimized hydroponic substrates, your microgreens benefit from rapid germination, clean cultivation, and easy harvest. Our low carbon footprint substrates and yield-enhancing fertilizers support your success from seeding to sale.

Oasis® AeroSelect™ PlugSheet for Microgreens

  • Engineered foam substrate for hydroponic microgreens.
  • Maximizes air porosity, drainage, and discourages algae.
  • Arrives clean, food-safe, and pathogen-free.
  • Promotes uniform germination and rapid root growth.
  • Stable air-to-water ratio for healthy plants.
  • Suitable for overhead or sub-irrigation.
  • Easy, clean harvesting—manual or automated.
  • Works with a wide range of microgreens (mustard, kale, radish, arugula, broccoli, chard, alfalfa, amaranth, basil).
