After positive results in 2016 in a pepper crop we continue this year with 2 crops of cucumbers.
In the peppers we installed our ‘washed type’ coirbags Double Layer. These we buffered and washed prior the trial started in a closed system.

This year we start crops of cucumber with washed / non-buffered Double Layer growbags straight in a closed system; results to follow end of this year.
For tomato crops we see our customers/grower already using our non-washed coir straight in closed systems successfully, as this example from Belgium:
