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 & staggering yieldsIt’s incredible.

You don’t need to worry about underwatering or overwatering – plants use what they need - no more, no less.

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

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 (2)

How many litres of air per minute does the air pump that is included provide? also how often would the 70 litre tank need replacing with fresh nutes?
The air pump that is supplied with the IWS Oxy-Pot XL provides 4 litres of air per minute. We would advise replacing the nutrient solution with a fresh batch every week, if you need to top up the solution between changes, it's best to use 1/4 strength nutrient solution.
