5. Tropicana Cookies Auto

This fantastic strain now in auto version by the Fast Buds team is one of our most potent strains. The extremely sticky flowers with up to 27% THC provides a very potent and long-lasting effect, perfect for hash makers that can ultimately end up with unique concentrates


“This is a nice evening strain for relaxing or if you want to chill with your friends. The effects start in the head but, for me at least, make me want to lie on the couch and chill. I am very impressed with this plant. The vape is flavourful though citrus is not what I typically go for when vaping. The citrus is most noticible at lower temps and it transitions to the creamy or woody flavour at high temps. I was leaning towards grapefruit, citrus and cream, which was not a bad guess given the released name is Tropicana Cookies” -CannabisTrope


Tropicana Cookies Auto is super easy to grow and is suited for all types of growers, her structure is tall and compact, and thanks to its Indica heritage will develop one large main cola and several fat side branches with really bushy foliage.

Make sure you have a carbon filter installed in the first weeks of flowering, the huge amount of trichomes also comes with a super pungent and intense smell, so we recommend having a way to eliminate the smell to avoid attracting unwanted attention and if you're cultivating outdoors you can try to plant aromatic plants to help mask and reduce the smell, which can travel very far with the wind.

6. In Conclusion

If you're looking for the most resinous, potent and highest THC cannabis seeds, here's what we recommend for your next grow cycle. All of these strains can be used for making extremely delicious concentrates like hash, extractions such as shatter or wax, or by keeping it simple and smoking the flowers in a joint, either way, they will leave you soaring through the skies for a long long time. Just remember that THC percentage is not the only thing important when talking about a certain strain’s effect, the terpenes are extremely important.

Just like aromatherapy, the terpenes in the trichomes are not only responsible for the aroma and flavor of a certain strain but also for the type of effect. This means that two strains can have the same THC percentage but have completely different types of high due to the different terpene profiles. Make sure to check each strain’s details in the table below.

We highly recommend that you take the terpenes into consideration the next time you’re shopping for cannabis seeds. As time passes you’ll be able to identify what terpene or terpene combination works better for you and improve your cannabis experience even more. Don’t think that the higher the THC, the better. As you may know, cannabinoids work in combination with terpenes and flavonoids, which are other chemical compounds found in cannabis plants that are not only responsible for flavors, colors and aromas, but also for the type of effect you experience when consuming a specific strain.

This means that the cannabinoid content (CBD, THC, among others) can give you an idea of how strong the effect will be but it’s the terpene profile that will dictate the type of effect you experience, for example, Limonene (the terpene responsible for citrus and most commonly, lemon aromas) will provide a more energizing type of effect while Linalool (the same terpene found in lavender plants) will provide a more relaxing and calming effect. In short, all cannabis will get you high but the terpene profile is what will eventually make a difference between a regular high and an unforgettable high. So feel free to check our catalog for the main aromas you get with each one of these strains and feel free to contact us if you need any help choosing the best terpenes for you.
