Crop King Seeds Information

Since being founded in 2005, the team at Crop King Seeds has been searching the world for the best strains and breeders. They aim to find the highest-yielding cannabis varieties and make them available to their customers. With everything from classic coffee shop strains to modern hybrids you’re sure to find something that suits you no matter how experienced a grower you are.

They work hard to ensure they only provide the highest quality seeds and build excellent relationships with their customers. Every seed is handpicked and tested to be mature and viable. If you have any questions or problems their customer service team can be contacted at any time of day or night.

Cannabis Seed Range

Crop King Seeds stocks over 400 of the world’s most impressive marijuana strains. While this isn’t the biggest selection available, it’s so well curated that you’re likely to find exactly what you’re looking for. With the simple navigation menu and various sorting options, it’s easy to find something that you’ll be keen to grow. However, because of the large number of strains available, it would also be useful to have some filters to narrow down the search.

The main options are autoflowering, CBD, feminized, mix and match, regular, fast version and new marijuana strains. Crop King Seeds currently stocks nearly 300 feminized, 40 regulars, 90 autoflowering and 44 high-CBD varieties.

Some of the popular strains they stock include:

  • Amnesia Haze
  • Jack Herer
  • Northern Lights
  • NYC Diesel
  • Sour Girl
  • Train Wreck
  • Durban Poison
  • Gelato
  • Green Crack
  • Purple Kush
  • Sour Diesel

Each seed page features lots of useful information including hybrid percentage, THC levels, CBD levels and strain-specific grow details.

Crop King Seeds Reviews

Crop King Seeds have thousands of customer reviews on Trustpilot. A large majority are positive and praise germination rate, speed of delivery and customer service. I was particularly impressed by how many mentioned that they were regular customers who’d returned multiple times.

Crop king seeds is #1 in my book! I’ve ordered seeds from many seed banks and I must say that as far as speed of shipment and quality of seeds goes CKS is the best! I can’t believe that my last order from them arrived in less than 5 days, 3 and 1/2 days and I received my beans! This is my 5th grow with CKS beans and the last 4 were awesome! I highly recommend CKS for Quality, Quickness, Customer service and for being able to chat with the king 24/7.

Tobias King believes that they are one of the best Seed Banks available.

This is the third time I grew with them. The first two I had 5/5 germinate, this time I only had 3/5 germinate. When I called they were super awesome and helpful. I’ve had nothing but good experiences with this company and with their product. I would highly recommend CKS. Will be buying again next round.

Ryan Kemmers was also happy even though some of his seeds didn’t germinate.

Ok so after calling I received my seeds in 5 days and they gave me 4 extra seeds…Customer service was great, and they were helpful.

Jamesha Jordan originally gave a one-star review but after contacting them, he was so pleased with their response he changed it to five stars.

Unfortunately, there were also several unhappy customers. 

Don’t waste your money. I planted seeds from several distributors and Crop King had the LOWEST germination rate even through I followed the infographic to a t. Then they give you a run around re their guarantee. You have to discuss your technique in detail over the phone. Why? I followed the instructions that were given via their website, why can’t they continue to communicate via the internet? Their guarantee does not say that a disappointed customer is required to face cross examination over the telephone.

Matthew Weldemann was disappointed with the rate of germination and the store policy of dealing with germination issues on the phone.

Crop King Seeds were quick to respond and explain the policy:

The call is a company policy so we may know as to where what went wrong and whether or not we could do a reshipment. When people get less than 80%, they are making a BIG mistake or they are trying to scam us. We will not be scammed. We watch our germination and genetics on a daily basis.
