Hydroponic Growth Module

2 reviews
The Hydroponic Growth Module has been a staple of the Urban Plant Growers range for years, being used in both the EcoKitchen and the Family Farm smart gardens. The module is a water reservoir with a 7L capacity, and HDPE construction. The design prevents light from reaching the nutrient-rich water - limiting the growth of algae in the basin, and leading to healthier and faster growing plants.
*Note the growth module is meant to be used with an EcoKitchen or Family Farm. Using the growth module without one of these products will require a light source and an aeration pump.


  • 7 Litre water reservoir
  • 12x net cups
  • 12x Rockwool cubes


  1. Connect basin lid to the base
  2. Insert net cups into slots in basin lid.
  3. Soak rockwool in water for 5 minutes.
  4. Cut rockwool with scissors
  5. Place rockwool cubes in net cups
  6. Add 2-5 seeds per cube - ensure all seeds are wet as this will activate the seeds
  7. After the seeds have sprouted and have formed their first few leaves, add 1 scoop of nutrients to the water and mix thoroughly to ensure it all dissolves.
  8. Add 1 scoop of nutrients per litre added from that point forward.


  • To reduce algae growth on rockwool, try to limit contact between rockwool and water.
  • High temperature water may cause stress in plant roots.

    Urban Plant Growers NZ Hydroponic Growth Module Review

    I’m in sustainable home living heaven

    I’ve bought a few items from Urban now and the latest, my special lights has been fabulous. I’m eager to have my seeds sprout and start growing. I’m also planning ahead foe winter to grow more veggies and rely less on store bought items. So exciting. Very pleased with the ordering and delivery process plus the customer service has been outstanding when I’ve had questions. Thanks Urban.
