ILGM Genetics
ILGM Genetics is the in-house seed line for I Love Growing Marijuana, founded by Dutch grower Robert Bergman in 2012. The team works with European breeders to produce feminized and autoflowering versions of legacy strains, with a focus on germination guarantees and beginner-friendly phenotypes that finish on schedule. The catalogue is split between licensed versions of well-known strains and a small number of in-house releases such as Gold Leaf, which is sold exclusively through the ILGM channel and its affiliate network. Quality control runs against Bergman's published grow guide, meaning seeds released under the ILGM label are stress-tested against the same instructions a first-time grower would follow. The brand also operates a free grower's forum that doubles as a feedback channel for catalogue improvements.
