About us
The origin of Ripper Seeds dates back to the early 2000s, when our fondness for this plant species became for almost all of us in our daily work. The Grow Shop sector was born and grew in the peninsula and we along with it. During this period we select different types of varieties that we still keep today. Our knowledgeC grew over the years but it was not until the middle of 2011 when we decided to meet and found Ripper Seeds. Since then we strive to make our work a little better every day and to be able to offer our followers high quality 100% feminized seeds.
