I’ve worked out an easy way to refresh nutrients in stand alone DWC systems. It involves using a container within a container. The internal container has holes drilled in it and houses the plant and aeration stone and tubing. When changing nutrients simply add fresh solution to a new clean container. Then lift the internal container out and transfer it to the new container. The benefits of this are:
- Ease of changing nutrients reduces barrier to proper maintenance.
- When changing nutrients, roots are not disturbed.
I’ve been changing nutrients for my year+ old Jamaican Hot Chocolate every two weeks, but the rate of consumption has increased and more solution needs to be added in between weeks.
Here’s a video I made showing the process:
