Self- watering pots are an innovative and truly unique growing system. They allow ordinary people to grow their plants with ease in the comfort of their own home. We've wrapped it all up in an easy to get started combo kit to help you hit the floor running!


Self-watering pots are a mess-free hydroponic growing pot that uses up to 90% less water than conventional soil pots. This means that you spend far less time watering your plants every time they dry up, freeing you up to leave your plants unattended for significant periods of time. 

By growing hydroponically you have the ability to use Hydroponic nutrients to provide the perfect blend of macro and micronutrients for plant growth. The pots can be used in conjunction with our EasyGro and BreezyGro lights to form a complete growing system that can be done completely indoors.

This product comes with Smart Soil and Expanded Clay, which is perfect for germinating seeds, and growing flowers, herbs, vegetables, and succulents. 


The 4 piece self watering pot combo kit comes with:

  • 3x 13cm square pots (3x water level indicator, 3x inner and 3x outer pots included)
  • 1x 23cm round self watering pot or 1x 40x18cm trough self-watering pot (1x water level indicator, 1x inner and 1x outer pots included)
  • 200mL Hydroponic nutrients for indoor plants
  • 1x 5L Smart Soil
  • 1x 5L Expanded Clay
  • Instructions

*grown plants not included


The Self-watering pots have an internal and external pot. The internal pot holds the smart soil, while the external pot allows for water storage without flooding your plants.

Growing in Smart Soil:

  1. Fill your Self-watering pots with smart soil.
  2. Add water until the water level indicator is 1cm from its maximum position.
  3. Add seeds and bury them as per seed specifications. Sprinkle water over the top to activate the seeds.
  4. Place pot in an appropriate place (under an EasyGro/BreezyGro light, or in the sun).
  5. Refill water when the indicator gets low. Add 5-10ml of nutrients per 1L of water. Don't overfill water.

Growing in Expanded Clay:

  1. Add a thin layer of expanded clay to the bottom of your pot.
  2. Place plant roots over the expanded clay, and add expanded clay around the plant to hold it in place.
  3. Mix 5-10mL of nutrients with 1L of water and add the solution to the pot until the water level indicator is 1cm from its maximum position.
  4. Place pot in an appropriate place (under an EasyGro/BreezyGro light, or in the sun).
  5. Refill water when the indicator shows low water levels. Add 1 scoop of nutrients per 1L of water. Don't overfill water.
Growth Mediums Smart Soil Expanded Clay
Typical uses

Smart soil can be used for germinating and growing plants from seed, or transplanting propagated plants.

Expanded clay does not hold any water, so if you plant seeds on it they won't grow. Expanded clay is awesome for growing plants that already have an existing root system - making it a great medium for propagations and transplants.

    Urban Plant Growers 4 Piece Self Watering Pot Combo Kit Review

    Self watering pots

    Easy to set up and fit nicely on my kitchen bench without looking out of place

    Hydro pot combo

    Urban plant growers products never disappoint. Quality pots and helpful service

    Good stuff

    The maxipot combo is a nice easy way to start growing plants. I think the smart soil is vermiculite mostly, it has interesting qualities as a soil replacement. My Spinach seeds germinated well on the first try and in a couple of months hope to have something nice to eat.


    Great product

    So happy with these pots. Easy to use, attractive and fantastic quality. Support Australian companies like these guys who are easy to deal with, passionate and informative.


    Good unit

    I love this product
