Know before you buy
Insect frass is the natural byproduct of insects, specifically black soldier fly larvae in this case. It is rich in chitin, which helps strengthen plant cell walls and encourages the plant's natural defense systems against pests and diseases.
Yes, this fertilizer is safe and effective for houseplants. Because it is organic and odorless, it is a great choice for indoor environments where you want to avoid synthetic chemicals.
To use as a foliar spray, steep the granular frass in water to create a tea, then strain the solids out before putting the liquid into your sprayer. This allows the nutrients to be absorbed directly through the leaves.
Yes, this fertilizer is considered vegan because it is a byproduct of insect farming that does not involve the slaughter or exploitation of animals. It is a plant-based nutrient source that aligns with vegan gardening practices.
The recommended application rate for containers is 1 cup per 1.0 cubic foot of soil. Simply mix the granules thoroughly into your potting medium before planting to ensure even nutrient distribution.
While the granules themselves are not water-soluble, you can incorporate them into hydroponic programs by brewing a compost tea with the frass and using the strained liquid in your reservoir. Be sure to monitor your system closely, as organic teas can sometimes cause clogging in fine emitters.
