Meet the plant
A plant. Nothing more.
Strip away nine decades of bad press and hemp is, finally, just a plant. It germinates in a week, grows tall and fast, puts down a deep taproot and produces a seed head full of protein, fibre and oil.
The leaves give it away. Five to eleven fingers, the silhouette everyone thinks they know. The seed is the whole point. Same plant we've been pressing since 2017.
