Silent Seeds: carrying on Dinafem with a new name

Silent Seeds is based in Rotterdam in Holland. The people behind it are the same ones who were part of Dinafem for years. They know what they are doing since they have been around since 2005. The team came back in 2021 under the name Silent Seeds. It feels like a continuation, not a restart. They focus on both feminized and autoflowering seeds. Some of the work is done together with Sherbinski, which is why you see a few new strains that feel closer to the American style.
