I have 4 mineral buckets for planting next year crops.
2 of the buckets are already made Wicking Containers check out ( Leon gardens ) and need to be reset for next year.
The other two are ready for what ever you want to do.
Now the red on had a hole and all it needs a 3/4 PVC plug you can see in the pictures.
2 that are wicking containers that have the PVC pipe are $ 20 each
the other 2 are 15 each
