If there is one variety responsible for the CBD movement, it's the Cannatonic strain. This unique hybrid cross (50% Indica and 50% Sativa) with lineage of the G13 Haze-male and the female MK Ultra is originally bred by the breeder Resin seeds. Specifically to create a strain with a high CBD content (12-19%) and a very low THC content (up to 6%).

Thanks to its great effects, the strain has become very popular in a relatively short time and is even called the mother of the CBD. For CBD enthusiasts, a real must.

The Cannatonic strain

The Cannatonic seeds are suitable for both indoor, outdoor and greenhouse environments. Especially with an indoor cultivation, the plant will develop in a healthy way and provide some serious yields. Although the strain isn’t extremely difficult to maintain, some experience is recommended. The plant is more susceptible to fungus. Therefore a controlled environment is preferred. In this way the plant can be exposed to the right temperatures and air flows.

Flowering time and plant height

The size of the strain is pretty limited. However, the plant develops beautiful aromatic icy green buds with a dense structure, beautiful trichomes, extreme amounts of Cannabidiol, little leaves and delicious lemon scents during flowering. The flowering time is about 9 to 10 weeks after which the plant reaches a maximum height of one meter and is ready to be harvested.

Strain yield

The Cannatonic feminized seeds produce plants with interesting yields that won’t disappoint. Although many types of outdoor species produce more weed than indoors, this doesn't apply to the Cannatonic strain. With this strain it’s exactly the other way around. The maximum harvest indoors is between 400 - 500 grams per m2, while outdoor and harvested at the beginning of October yields will be between 250 - 400 grams per m2 on average.

Cannatonic weed: taste and aroma

The smell of this weed is just amazing. Although the scents show woody (pine) and earthy notes, the Cannatonic weed with its soft citrus flavor is surprisingly sweet.

Smoke report: the weed effects

Cannatonic is an incredible strain with unique lab results and a great terpene profile. The test results show that the ratio of THC / CBD is 1: 1 to 1: 2. As you can expect from such a CBD rich species, Cannatonic weed offers a long-lasting relaxed and euphoric experience. In particular, inexperienced smokers will experience a slightly brightening "head-high", but the effect is mainly focused on the physical parts of the body. This physical buzz is quickly noticeable and creates a strong calming feeling. Due to the very low THC content you don’t have to be afraid to become anxious or paranoia.

Was happily surprised when I received my order, no problems at all. Great shipping techniques.....haven’t used them yet, still a little cool at night. Next week I will start. Loved the service and all the great information you and your friends had to give. I have recommended your site and services to several of my friends. Thanks again

Agnes (verified customer) 2019-11-08

I thought the THC would be negligible, but still I got a bit high of this strain. For most people it probably isn't a problem, but I really don't like getting high. I only take the CBD for medical purposes... Frank recommended me to take Charlottes Web next time if don't wanna any THC.

PinkFlorina (verified customer) 2019-08-23

Just want to say thinks for your service, secure shipment method and great support team.

AAJ Stith (verified customer) 2019-05-08

I remember that i had a great chat with Frank who recommended me the Cannatonic. Had grown ACDC and Harlequin before so i can tell you...this strain certainly matches the quality of strains like Harlequin and ACDC.

Erin Lane (verified customer) 2019-03-28

Although i have germinating my seeds directly in the soil for years with great success, this time was a bit different. Out of 5 only 2 came up so i was a bit disappointed at first. Yet, after reporting my issue via the customer care section Frank send me 5 new extra seeds and a link to their blog about how to germinate the seeds properly. With these methods (soaking in water first for 24 hours) and then applying the paper towel method all my 5 seeds sprouted. The 3 star rating is because of the delay due to the none-germinating seeds. Yet, i would like to give a 5 star rating for your customer care. It just amazing to have found a company who indeed care about their customers, so thank you thank you thank you!

I'm a Vet and in chronic pain but this purchased helped me a lot. Cannatonic is pretty easy to grow. Good yields but especially the effect is very good! The very low THC level is almost not noticeable ( i don't like to be high) while the CBD ensures that my entire body relaxes and is painless. Gonna buy some more soon guys.

Francis (verified customer) 2019-02-21

What a great strain. The seeds where an excellent choice while the plant doesn't grow that large so they where very suitable for my indoor grow. Ive been growing some great healthy plants and really, the weed is amazing. Besides the service at Weedseedsexpress is topnotch! High recommendable!

James S. Hernandez (verified customer) 2019-01-10

Although breeding a quality CBD strain is generally more difficult, I am a big fan of high CBD strains. My favorites are ACDC, Charlotte's Web and this Cannatonic. All these strains ensure a wonderfully relaxed effect, which is especially pleasant during the day and in the evening before I go to sleep.

Kuntz (verified customer) 2018-12-25

Good seeds and with the paper towel method i manged to germinate 18 out of 20 seeds, so I think that's a pretty good score.

L. Garcia (verified customer) 2018-12-10

Although these are good CBD seeds and I can recommend these seeds to anyone who wants to grow a CBD strain, my preference goes to the ACDC. Especially because AC DC possesses more Sativa properties.

Buckley (verified customer) 2018-11-07

This was the first time I bought CBD seeds and bred a CBD strain, but I think I will never grow anything else anymore. What a beauty of a plant! It is a relatively small plant but certainly one of the nicest I have grown so far. Love to the great support team for WSE. It was a real pleasure buying your seeds.

J. Younger (verified customer) 2018-09-02

High quality seeds and inexpensive prices. Moreover, the service here is very good. Because a seed did not germinate, I received an extra seed in my last order. Very attentive of customer service. See you guys soon!

Joshua H. (verified customer) 2018-08-05

Although paying through the website was a bit cumbersome, I received the seeds in good order. Moreover, the communication was good and the employees are helpful. However, I have experienced problems with the germination of the seeds, but perhaps that is because I do this for the first time.

R. Dugan (verified customer) 2018-07-14

As a medicinal user I had been looking for a strain for a while to use during the day, but because the range at the dispensary is limited, I decided to buy these seeds and grow my own plant. That may have been the best decision ever. The plant develops in a very natural way. Moreover, my weed is now 100% sure organic, the effect is amazing to my body en the taste is lovely citruslike.

Jamison (verified customer) 2018-06-08

If you are looking for a high quality CBD strain, I can recommend these seeds. It's by far the best CBD strain I have bred and smoked. The effect is so amazing. After a few hits I felt the pain in my body and the worries disappear from my head.
