How they Work

Plants grow in a mesh pot filled with clay pebbles. Roots grow out of the mesh pot, straight into an oxygen rich nutrient solution.

This gives them a constant, unlimited supply of nutrients, and plenty of oxygen. You can expect explosive root growth & jaw dropping yieldsIt’s incredible.

There’s no worry of underwatering or overwatering either – plants use what they need.

• Explosive root growth
• Faster nutrient uptake
• Mind blowing yields
• No underwatering or overwatering

Plants started in rockwool cubes, root riots or jiffys can be transplanted into an Oxy-Pot. Make sure that they are root bound before transplanting.

Feeding your plants

Avoid using any nutrients that are organic -active systems and biological ingredients don’t mix well. We recommend using SHOGUN Samurai’s hydroponic nutrients, which are mineral based.  

You need to completely change your solution roughly every 2 – 3 weeks, topping up in between changes.

Plants under lights tent to absorb more water than nutrients. To keep your nutrient strength from rising, top up the pot with half strength nutrient solution between changes. Take an EC reading and add more nutrients if you need to. Don’t forget to monitor and tweak your pH.


Leave the pump on 24/7 – never let plant roots dry.

Q & A

Questions and Answers (1)

Hi I'm new to the oxypot 4 , how do I clean/maintain it with out removing the 4 plants especially when they are large ? Should I be looking to add a drain off point to the tank so I can clean / flush whilst the plants remain in the tank ? What would you use to clean the tank , thanks for your time , I await your reply Gary mabbat
The easiest way to change the solution the IWS Oxypot 4 is to use a pump to drain the tank. You can easily access the tank via the access port on the top of the system. We would recommend using a solution of Oxyplus to steralise the system between crops.
