Get to know your bulk cannabis seed breeder!

I’m known as MrSoul, I am the founder of Brothers Grimm Seeds and the original breeder of the well-known and celebrated Cinderella 99. My education and experience as a nuclear engineer trained me to approach breeding very scientifically. Brothers Grimm is uniquely qualified to produce pure female cannabis seeds without intersex issues.

My clients have grown tens of thousands, even hundreds of thousands of my bulk seeds. They all report consistently female plants with excellent yield and desirable cannabinoid and terpene profiles.

My history in the bulk cannabis seed business dates back to 1987, when I worked for Super Sativa Seed Club of Amsterdam, Netherlands. That experience launched my career in cannabis, allowing me to learn the seed business, as well as experiment with breeding over 40 different varieties of cannabis.

I’m extremely passionate about breeding and supplying the most stable and highest quality female seeds in bulk quantities to suit commercial cannabis growers. As I always say, “Genetics are the most important thing, everything else is just environment.”

There are many huge benefits for commercial growers when they start their crops from female seeds as opposed to growing clones. Seeds can be started on the exact day of your choosing, whereas clones are already growing when you get them. Seedlings are also more vigorous as compared to clones, producing more yield and fewer weak plants.

Bulk seeds are the best option for commercial cannabis farms, greenhouses and indoor grows, and Brothers Grimm Seeds has the most reliable and uniform genetics they could hope for. Farms growing hundreds of thousands of plants have gotten 100% female plants every time with our designer genetics. You won’t be disappointed either!
