Research & Development at Grandma’s Genetics

Research & Development at Grandma's Genetics

Between the numerous blogs and seed banks in the cannabis field, we have made it our goal to explain and at the same time promote the topic of breeding and R&D from the ground up so that others can benefit from it as well. Knowledge should always be free in the first place and science […]

CRISPR/Cas9 in Cannabis – The Future of Genetic Engineering

What is CRISPR? CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is an innovative biotechnology tool based on a natural safety function in bacteria. It uses a protein called Cas9 and a bound RNA (gRNA) with a 17-20 nucleotide sequence to recognize and cut specific segments of DNA. In biotechnology, CRISPR is used as genetic scissors […]

Hermaphrodites – origins, implications and what the future holds


Hermaphrodite plants are natural and part of cultivating cannabis, even if it is an uncomfortable topic with many. But is their reputation really that bad? It has not been scientifically proven that hermaphroditism is a negative trait in cannabis plants. However, it is important to note that hermaphroditism can also have disadvantages, such as passing […]

What does F1, S1, BX1 & IBL stand for?

Seeds by Grandma's Genetics

“F1”, “IBL”, “BX” and “S1” are terms used in cannabis breeding to describe different generations of cannabis strains. Here are the main differences: F1 F1 stands for “First Hybrid Generation”. It is the first generation resulting from a cross between two different parent plants. Often F1 hybrid plants show distinct traits of the pollinated mother […]

Differences between Regular, Feminized and Automatic Seeds

Seeds by Grandma's Genetics

Regular, feminized and automatic seeds differ in terms of their use and purpose in growing cannabis. Automatic Seeds Automatic or ruderalis genetics in cannabis refers to plants that self-pollinate independently of light cycles and thus flower automatically. This type of cannabis plant is shorter and bushier than regular or feminized plants, making it more suitable […]

THC, CBD, CBG & CBN: The best-known cannabinoids at a glance

The ingredients of the cannabis plant have fascinated us humans for over 5000 years. Even our grandma’s grandma used the power of the cannabis plant to relieve toothache or simply to sleep better at night. Cannabis has also manifested its importance in the shamanistic tradition thousands of years ago. The ingredients of the cannabis plant […]

What does breeding actually mean?

Plant Pollination by Grandma's Genetics

The aim of plant breeding is the genetic modification of plant populations to improve biological and economic properties. It is based on plant selection, seed treatment or crossing with subsequent selection of daughter plants for the next breeding cycle or subsequent propagation as seeds of a new plant variety (seed breeding). Since you have now […]

Genotype vs. Phenotype – What’s the difference?

Genotype vs. Phenotype

Genotype and phenotype are terms used in genetics and refer to the characteristics of plants. Genotype refers to all the genetic information of a plant stored in its chromosomes. This includes both visible traits (e.g. color of flowers or shape of leaves) and invisible traits (e.g. susceptibility to certain diseases). Phenotype refers to the visible […]
