Blossom Blood is a very unusual product that expands flowers in seed crops. Blossom Blood expands the actual flower creating "space" for protective resin drops to form within the flowers. This process "fluffs" up the yield and allows the drying process to take place faster. It also reduces the risk of moulds/fungi growing within the flower due to excess humidity or damp storage. The most important aspect of the product is that a little is good, less is better. If you use too much you will wish you had not. When growers start using Blossom Blood it is important to use less than the recommended amount.

Use when the flower buds are definitely developing (in the expansion stage) and the grower is sure that the plant is well into the reproductive stage. If it is used too early it will not be as effective and can delay flowering (in some varieties it can create some interesting vegetative growth).
