Prismarine Shards are items added in 14w25a that can be obtained by defeating the Guardian mob. They can be crafted into Prismarine variants such as Prismarine Brick and Dark Prismarine.
After veg they will usually flower for anywhere for 8 to 9 weeks. The breeder recommends growing Jack Berry F2 in a SCRoG type grow, where the yield can reach above average, at best. This is a strain that spends most of its energy developing trichomes, rather than bud mass. Don't expect huge yields with this one. In most cases, it simply isn't possible.
If the two traits are unlinked and the F1-plants are self-fertilized, in the F2 generation plants we expect the 9:3:3:1 ratio of offspring: 9/16 tall plants with spherical seeds. 3/16 tall plants with dented seeds.3/16 short plants with spherical seeds. 1/16 short plants with dented seeds.n a dihybrid cross between plants with tall stems and spherical seeds (both dominant) and plants with short stems and dented seeds, all of the F1-hybrid plants would have both dominant characteristics. The dihybrid cross is SSTT x sstt.
