Leaf feeding, Environment, Media & Nutrition
Key takeaways:
- Foliar feeding delivers nutrients quickly through plant leaves.
- Common in cannabis cultivation to address nutrient deficiencies.
- Used as a supplement to soil or hydroponic feeding methods.
- Can improve plant health and increase yields.
What it is / How it shows up:
Foliar feed is a nutrient application method often mentioned in cannabis cultivation guides, forums, or product descriptions. This technique involves spraying a nutrient solution directly onto the leaves of cannabis plants. By doing this, plants can absorb nutrients more rapidly than through soil or growing media, making it a popular choice for addressing nutrient deficiencies. It is typically used alongside traditional soil or hydroponic feeding to provide a nutrient boost and is particularly favoured when quick action is needed.
How it’s measured or identified:
- Through observation of plant response post-application.
- Measurement of nutrient solution concentration.
- Checking pH levels of the solution.
Use in context:
- "I used a foliar feed to quickly address the nitrogen deficiency in my plants."
- "Foliar feeding is especially useful during the vegetative stage."
- "Ensure the foliar spray is applied in the morning or evening to prevent leaf burn."
Safety & compliance in Canada:
- Ensure foliar feed solutions are approved for use in Canada.
- Follow recommended application rates to avoid plant damage.
