Rainbows XXL Auto

Rainbows XXL Auto, a product of five years of development and four generations of crossbreeding, brings the advantageous qualities of the BSF Seeds champion Rainbows Fem into an autoflowering variant. This strain stands out for its ease of cultivation, structural stability, and impressive production levels.

It exhibits a stout structure with a prominent central cola and uniformly tall lateral branches, paired with beneficial internodal spacing. This spacing is optimal for light training techniques such as Low Stress Training (LST), encouraging the growth of hefty, dense buds. For growers, this means Rainbows XXL Auto is not only productive but also adaptable to various cultivation practices, although support for its branches becomes necessary as it matures due to the weighty buds it develops.

When cultivated indoors under ideal conditions, it boasts a remarkable yield that can reach up to 500g/m2. The strain’s effects are predominantly Indica, offering a mix of sedation and euphoria which makes it an excellent choice for daytime relaxation or stress relief. Its noteworthy THC concentration, between 22% and 23%, ensures a potent and blissful experience. The flavor profile is sweet, echoing a blend of earthy notes and sweet grapefruit, attributed to its dominant terpenes: beta myrcene and beta caryophyllene.
