HumboldtsSecret Sprays Editorial Review
Humboldt’s Secret Flower Shield is a non-organic multi-purpose insecticide suitable for most plants, including cannabis. The product can treat and protect against common pests and mold, and reviewers commend it for promoting healthy and strong foliage. Some users say it has effectively eliminated russet mites and 90% of scale insects. However, others note it failed to kill aphids, spider mites and fungus gnats. It is recommended to avoid spraying the soil and to wait for the product to evaporate before exposing the plants to light. The size-to-price ratio is unfavourable, considering the small bottle can only treat one gallon. Some users say it worked well beyond the two-month shelf-life, while others say they experienced a sticky residue on their buds and an unpleasant taste.
