Alchimiaweb and Underground Seeds Collective present here the Coljam aka "Colija", a pure Sativa cannabis strain developed by crossing Colombian and Jamaican genetics. Highly psychedelic, strong and a true high yielder.

This F1 cross between the Colombian Gold strain and the Jamaican Lambsbread grows tall and fir-shaped, developing long internodal distances. It is extremely vigorous, growing really tall even during the flowering period.

It is ripe in 14-16 weeks of bloom, yielding up to 600gr/m2, offsetting the long flowering stage.

The aroma is complex and intense, ranging from fruity notes reminiscent of lychee to spicy and Haze hints, depending on phenotypes.

The effect is highly psychedelic, electric and very intense. It is followed by a strong physical relaxation feeling, very pleasant and balanced.

Coljam aka "Colija" from Underground Seeds features:

  • Genetics: Colombian Gold x Jamaican Lambsbread
  • Type: Regular seeds
  • 100% Sativa
  • Flowering: 14-16 weeks
  • Yield: up to 600gr/m2
