From the parents of Positronics Critical #47 strains, they retain the aroma, taste, production in this version of Express. After a long journey, they decided to cross the mother with their Low Ryder II variety and produce an auto-flowering variety with a clear Critical taste. Its basic property, besides its speed in the vegetative state, is a considerable size with minimal distances between sets of branches, and it also has many side branches, allowing it to produce more flowers with Critical Mass features and develop large and compact buds.

When planting, it is important to plant it in a pot in which it will remain for the duration of growing, or replant it as soon as possible in order not to limit its final size. Its susceptibility to mould development is moderate and does not tolerate large amounts of fertilizer.
