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!

Buying cannabis seeds in bulk
Cannabis seed buyers tend to be split into three main groups. Many just buy their cannabis seeds as they are required for each grow. Others, perhaps the majority of growers, tend to buy a few extra seeds in order to maintain a healthy collection of spare seeds, just in case. But a minority of cannabis growers buy their cannabis seeds in bulk, hundreds and sometimes thousands of cannabis seeds at a time.
Bulk cannabis seed orders are often placed by large, licensed cannabis producers. Large cannabis seed resellers often buy cannabis seeds in bulk from several different suppliers/brands, these are sold online or via bricks-and-mortar seed shops/head shops.
The Covid 19 pandemic increased the number of bulk cannabis seed purchases. Without doubt that was partly to offset concerns about future seed supply disruptions. But what are the other reasons to buy weed seeds in bulk, what are the benefits and risks? Can you save much cash by buying cannabis seeds in bulk?
It’s important to note that bulk cannabis seed sales are not intended or required for the self-sufficient home grower. Such growers tend to need just a packet or two of seeds each year. But the increasing numbers of legal, licensed cannabis producers has created a new market for bulk cannabis seeds. Some of these growers will import several hundred (or more) cannabis seeds of each strain for large scale commercial production.

The quantity of cannabis seeds in bulk
The small-scale self-sufficient grower may only grow 4-5 plants a couple of times a year. To such growers, buying 25-50 cannabis seeds at a time may feel like a bulk buy. Especially if they are used to buying packs of 5 seeds at a time.
But to commercial growers harvesting thousands of plants, buying bulk cannabis seeds in quantities of hundreds or thousands may be necessary on a routine basis. Many such growers use thousands of seeds each year for plant production, pheno hunting, research etc. To most industry professionals, bulk bought cannabis seeds infers thousands of seeds.
The good news is that some of the best seed banks are geared up towards offering bulk sales in varying purchase quantities. Buying bulk cannabis seeds will mean discounted prices. But not all bulk cannabis seed sellers offer the same quality. One of the biggest risks with bulk seed purchases is avoiding the low-quality seed vendors and low performance genetics.
Indoor vs outdoor bulk cannabis seeds
Bulk cannabis seed buyers are split into two main categories – indoor and and outdoor growers. In countries with warm outdoor regions such as USA, Australia etc many large commercial growers prefer to grow outdoors or in greenhouses. This allows significant cost savings with less reliance on indoor lighting and expensive indoor grow rooms.
Many such outdoor growers carefully select their bulk cannabis seed purchases to ensure compatibility with their local climate. Companies such as Dutch Passion are happy to meet such growers and discuss their specific outdoor genetics in detail. Factors such as the length of the grow season, local temperatures/humidity through the season etc all have an impact on the final seed selection. Some outdoor growers prefer to grow photoperiod feminised cannabis seeds. Many prefer the speed and convenience of autoflower seeds.
Indoor growers often have greater control of their grow environment than outdoor growers, able to dial in all parameters from lighting levels, temperatures, humidity and even pest control. With a wider choice of cannabis seeds and strains available, the indoor grower has some great options even if the cost of growing may be higher than outdoor/greenhouse growing.
Buying bulk cannabis seeds for indoor growing
Indoor growers can produce the best quality and cannabinoid levels assuming they have full control over their environment and have bought the best technology, e.g. LED grow lights, and invested in experienced staff. Most indoor growers aim for the highest THC levels alongside heavy yields. A sizeable minority of indoor growers also grow cannabis seeds rich in CBD and other special cannabinoids such as THCV, CBDV, CBG etc. These are proving of increased interest to medical marijuana users and pharmaceutical companies.
|Dutch Passion special cannabinoid cannabis seed collection|
With full control of the indoor environment, just about all cannabis genetics can be grown indoors from fast, compact indica strains to stretchy longer blooming sativa seeds. These days, feminised seeds and autoflower seeds are equally popular with indoor growers and account for the majority of bulk cannabis seed purchases. Regular cannabis seeds tend to be a niche market for old school growers. But it’s worth adding that some licensed legal growers do make bulk regular seed purchases for some of their own breeding experiments.
If you are buying bulk cannabis seeds for indoor (or outdoor) growing then Dutch Passion are unusual in that they can supply seeds with Dutch Government-approved Phytosanitary Certificates to guarantee that the seeds are free of pests and disease. Phytosanitary certificates are often mandatory when bulk buying cannabis seeds for legal grows, Dutch Passion have supplied such certificates to indoor (and outdoor) growers all around the world.
Buying bulk cannabis seeds for outdoor growing
Outdoor growers enjoy using the sun as their primary light source, saving large amounts of cash over indoor growers who have to buy and power their indoor lights. If you grow in a good/stable outdoor climate then the cost savings may justify the occasional risks associated with adverse outdoor weather.
Often, but not always, outdoor growers will use poly tunnels or large commercial greenhouses to protect their plants from the worst of the weather. The strain will be selected to ensure that it is robust enough to cope with the local climate at that latitude as well as being able to ripen before the cooler late-season weather arrives.
Feminised seeds tend to deliver the heaviest harvests, but autoflower seeds can allow multiple successive harvests in the same grow season. Often growers will have hundreds or even thousands of plants. This requires bulk cannabis seed purchases of thousands of seeds at a time.
With so many plants, the cannabis genetics are vitally important. Buy the wrong outdoor bulk cannabis seeds and your plants may be completely incompatible with the climate. Outdoor growers need genetics that have been selectively bred over many generations to be weather resistant, dependable and able to tolerate sub-optimised conditions.
If you are bulk buying outdoor cannabis seeds it helps to deal with companies that can boast several years experience supplying to licensed outdoor growers.
The price of cannabis seeds in bulk
The main advantage of bulk buying cannabis seeds is the price saving. This will vary depending on purchase size. The cost of 10 premium quality feminised cannabis seeds is typically in the range of €/£/$100, or around €/£/$10 per seed. However, if you buy cannabis seeds in bulk (thousands of seeds) you may be paying a lot less, below half those prices and maybe much lower.
The cost savings come since the seed supplier is creating just a single shipment of several thousand seeds rather than hundreds of smaller orders. Administration/packaging costs are a fraction of those when fulfilling a bulk cannabis seed order.
However, it’s worth adding that the actual cost savings will vary from supplier to supplier. Some here-today gone-tomorrow seed companies specialise in supplying low-cost, low-quality bulk cannabis seeds. These are popular with lower quality seed resellers who buy them, re-label as their own creation and try to sell at high prices.
Other companies specialise in pioneering high quality cannabis genetics, these cannabis seed suppliers tend to be the ones that survive into the long term.
Bulk buying cannabis seeds? Know the risks….
The old phrase, ‘buyer beware’ is just as important when buying bulk cannabis seeds as it is in with any other purchase. Judgement can be clouded by cheap prices, if something sounds too cheap to be true then perhaps you are correct to be cautious.
Remember that the best growers in the world cannot produce high THC harvests from low quality cannabis seeds. Low quality cannabis seeds permanently damage reputations.
There have even been confirmed cases of people selling ultra-low THC hemp seeds (very cheap to buy and may look similar to cannabis seeds) and selling them as cannabis seeds. Imagine spending thousands of Euros/Pounds or Dollars on completely useless bulk cannabis seeds which are actually hemp!
Always remember that the premium quality cannabis seed producers rely heavily on genetic consistency and the best will use systematic laboratory cannabinoid/terpene testing at each stage of the seed production process to ensure that standards are correctly maintained. The top seed suppliers also rely heavily on their reputation, they simply can’t afford to sell low quality genetics.
The quality of cannabis seeds in bulk
It’s crucial to understand the wide discrepancies in standards between an established quality cannabis seed supplier vs a low-end supplier that buys the cheapest wholesale seeds available, re-brands them and sells them on at inflated prices with a fancy new strain name and description.
Cannabis seeds really are not a commodity, quality between the best and worst suppliers has always varied tremendously. Even high-priced cannabis seeds are not necessarily a guarantee of quality. The main guide for any potential seed buyer is the reputation of the seed company and the accuracy of their product descriptions.
Has your seed supplier stood the test of time over a few decades? Have they collected plenty of cannabis cups along the way and established a good reputation?
Those that bulk buy thousands of cannabis seeds prefer to buy them from the same companies which have established the best reputations with self-sufficient home growers. Even a small home grower senses an element of risk when buying unknown cannabis seeds from an unproven supplier. Large, licensed cannabis producers simply can’t afford to take such risks when their business depends on the quality of the genetics they grow.

How to store your bulk cannabis seeds
The type of grower that actually needs to bulk buy cannabis seeds (large, licensed, legal producers) tends to use all the seeds fairly quickly. This contrasts with the typical home grower who only needs a packet of seeds or two each year and will store any unused seeds in their fridge for the following years.
Often home growers will slowly build up a collection of their favourite cannabis seeds and store them in the fridge, where they will remain viable for a decade or maybe longer.
However, it should be noted that cannabis seed viability tends to decrease as seeds get older, especially when left unrefrigerated. If you do struggle to germinate cannabis seeds the following fully proven method should help, even if the seeds are old! It’s the best cannabis seed germination method that Dutch Passion have found over the decades.
|Best way to germinate cannabis seeds – the cotton pad method|
In general a good way to store any cannabis seeds is in the fridge. The low temperatures help maintain seed viability for many years. Cannabis seed companies may also use low temperature freezers for very long-term storage of special genetics.
Seeds can remain viable for decades in a freezer but must be handled with extreme care since the delicate internal seed contents can shatter if roughly handled.
Buying cannabis seeds in bulk
If you’re buying cannabis seeds in bulk, you can’t afford to take any chances. A bad harvest that involves hundreds (or thousands) of plants can be enough to bankrupt a licensed cannabis producer. Dealing with the best suppliers may not get you the cheapest bulk cannabis seeds, but you will get guaranteed genetics that can be relied on to build your business.
