Pucuk means canopy leaf and in Malaysia, means the top shoots of the plant. The tops of the trees form a canopy. Basically pucuk is top growth or the leaf that is directly exposed to sunlight.
This is pucuk leaf from Banjarmasin. Many consider this to be the best type of leaf to harvest and the strongest due to the energy focused on top and new growth, as well as the direct sunlight effects on metabolism. It gets a complete indoor dry and smooth grind. Very nice strain.
