Humboldt Sticky


Foliar sprays are a quick way to get nutrients to your plants directly through the leaf tissue. We also use foliar sprays to apply insecticides and fungicides. A proper foliar spray should always include a wetting and binding agent to equally distribute and adhere the spray onto the plant’s leaves. Humboldt Sticky is our premium wetting agent formulated using premium ingredients. Humboldt Sticky can help gardeners get the most efficacy out of any foliar applications.

Directions For Foliar Spray:

  • STEP 1: Combine 15-30 milliliters (0.5 – 1 fl oz) of Humboldt Sticky for each gallon of NON-CHLORINATED water. Shake solution vigorously.
  • STEP 2: Add nutrients and additives to the solution. Be sure to always add your bloom fertilizers or boosters into the mixture last. Shake vigorously once again.
  • STEP 3: Spray solution evenly on garden when the sun is setting, or when lights are turning off; or alternatively when sun is coming up, or just before lights are turned on. Stomata open up under light and slowly close during the night. Humboldt Nutrients suggests spraying when the sun is setting, this way you can alleviate evaporation of Foliar spray and the danger of foliar burns. Always maintain a clean foliar spray bottle and a freshly mixed solution (NO sediment). Be cautious of your lights! Water and hot bulbs Do Not Get Along With Each Other.
Most foliar sprays are used throughout the vegetative stage and up through the third week of bloom.
