Someone has been trying to grow cannabis in the middle of a field in the upper Swansea Valley.
A total of 54 plants have been discovered on land between Caer-Lan and Abercrave .
They could be seen coming out of the soil surrounded by mesh tree guards, with bamboo sticks to support them.
It is not yet known who planted them in the area.
Dyfed-Powys Police confirmed the plants were growing on private land and that there had been no arrests so far.
A spokeswoman for the force said: "The plants were growing on private land between Caer-Lan and Abercrave.
"There were 54 of them - they were young plants.
