While lower in THC compared to most cannabis strains Cannatonic will still give cause a gentle high, particularly in people with a lower tolerance.

Appearance and Aroma

Cannatonic has dense clusters of pale green brown buds covered in yellow and orange pistils and tiny sugar leaves, with the buds themselves look like of popcorn or granola pieces.

    Don't let the high CBD fool you. This strain still gives you a nice high. I use it for stress, Depression, and Autism. A nice relaxing mellow feeling. Makes me feel calm and happy. Not harsh at all and gives you a good yield. Had a few mite problems at the end of my grow but not as bad as others.

  • "Calms me right down"

    Review by

    I had been dealing with anti-depressants for years and while cannabis had been recommended, I didn't really want to get high. Finally, after barely fighting off a bad panic attack, tried Cannatonic and realized I've been high all these years! So much more effective than taking pills, and I was super calm but not spacey or giggly. I love this strain. I only wish I had tried it sooner.

  • "Great Strain"

    Review by

    This is a great strain. Great for SOG in my opinion, which I wish I had known. To my surprise, they all finished within 56 days (some were done by day 50). The odor is similar to a kush variety and it puts out really dense flowers. The only issue that I was concerned with was that they couldn't handle nutrients too well, so you should tread carefully with your feeding regimen. Overall, an excellent strain that's definitely in my top 8 list. MSNL rarely disappoints and I was more than happy with this strain. Will definitely get again and keep now.

  • "Awesome strain"
