DELEAFING / DEFOLIATING SOP
“Deleafing” or defoliating a canopy is the process of selectively pulling leaves for beneficial purposes. It is a process that can be used to promote lower growth and flower size, as well as help the flower to
finish evenly and thoroughly throughout the canopy. If not done correctly, it can affect the yield and health of the plant. It is important to understand that this process is time sensitive and dependent on
factors including plant maturity and health.

ITEMS NEEDED:
GLOVES, TRASH BAGS, 5 GAL BUCKET, WASTE BIN

LIGHT DELEAF
“Light Deleaf” refers to pulling minimal amount of leaf and being selective of the leaves pulled. Expose possible tops within the middle of the canopy with the intent to even out height of canopy and promote
more tops. Light deleaf usually occurs during early flower. Excessive deleafing in early flower may stress or stunt the development of the plant.

  • Exposing potential tops within the canopy.
  • Less than 20% of foliage removed.
  • Usually done earlier in the flower cycle.
  • Do not pull leaves from the highest 3 nodes of the stock.

HEAVY DELEAF
A “heavy deleaf” refers to defoliating the middle of the canopy between the second trellis and first trellis with the intent to expose interior growth to light and air. Large fan leaves in the middle of canopy can be taken, to allow room for newer smaller leaves and developing node sites. You should be able to see light through the bottom of the canopy, but from a side perspective canopy should still appear full
with plenty of foliage throughout.

  • Creating pockets of light that can be seen through the bottom of the canopy.
  • Leaves taken from middle of canopy leaving a layer foliage at the top and bottom of canopy.
  • Less than 50% of foliage removed.

STRIP
A “Strip” refers to the process of taking around 90% of leave content from plants. This process will help develop maturing flower and ensure an even finish through out the height of the canopy. Stripping a plant should be reserved for the final weeks of flower in preparation for harvesting.
