Know before you buy
It acts as a binding agent that helps your nutrient solution spread evenly across the leaf surface and stick there. This prevents the liquid from beading up or rolling off, ensuring the plant absorbs the nutrients directly through the foliage.
Yes, Humboldt Sticky is formulated to be safe for use on vegetables, flowers, and a wide variety of other plants. Its natural biochemical process is gentle on plant tissue while maximizing nutrient uptake.
No, it is a sticking and wetting agent, not a standalone fertilizer. You should use it as an additive to your existing foliar spray regimen to help those nutrients adhere better to your plants.
By ensuring more efficient nutrient delivery directly to the plant, Humboldt Sticky helps support healthier growth. This improved uptake can lead to more aromatic crops with richer flavor profiles compared to sprays that simply run off the leaves.
No, this product is a liquid concentrate designed to be mixed into your spray solution. It is specifically engineered to create a microscopic bond between the spray and the leaf, rather than dissolving into the water like a traditional fertilizer.
