The Highest THC Seeds
An in-depth review of the 15 highest THC seeds available. Discover a world filled with bone-crushing indicas and psychedelic sativas and find high THC seeds for sale.
When you want weed that will knock you off your feet, there’s no better choice than high THC seeds.
Cultivators worldwide prioritize high THC seeds because most cannabis enthusiasts seek the most potent strains available. Whether for medical or recreational purposes, the concentration of THC is paramount.
Many medical marijuana patients seek weed that contains upwards of 30% THC to nip discomfort in the bud. Alternatively, recreational marijuana enthusiasts seek cannabis that exceeds the 35% THC mark to explore the mind’s boundaries. Regardless of your reason, choosing a strain with high THC is almost always an excellent choice.
High THC seeds, however, are not easy to come by. The vast majority of the highest THC strains are not for sale because they are closely guarded. Due to their rarity, high THC strains typically form the backbone of a cannabis seed company’s catalog.
Furthermore, the highest THC strains are kept as an ace-in-the-hole during cannabis competitions, such as High Times or Spannabis. Overall, you’ll be hard-pressed to coerce a breeder to give up a legendary cutting of a high THC strain.
Luckily for you, a handful of coveted high THC seeds are available — if you know where to look. Read along to discover the criterion to select the highest THC seeds for your needs.
How to Choose The Highest THC Seeds
As a cultivator, you must search for a cannabis strain that ticks all the boxes — not just THC potential. What use is a high THC strain if it tastes terrible, or worse, yields a handful of grams?
Overall, the point is to find the highest THC strains that’ll put you down-for-the-count while being enjoyable to grow and experience.
Now, let’s take a look at the different aspects that you must consider before you buy high THC seeds.
If you want high THC seeds, this is the first aspect that you need to look at.
Sure, 25% THC is potent, but why not find seeds that contain 35% THC? Once again, it’s all about you. Therefore, only you can decide if a 20-30% THC strain is right for your needs.
Are you searching for an indica, sativa, or hybrid?
The type of cannabis strain makes a massive difference, so you must choose accordingly. The last thing you want is to grow a psychedelic sativa only to realize you suffer from anxiety.
Overall, you must look at the effects of a high THC strain and determine if it produces results that you will enjoy.
The grow difficulty of a strain is a vital aspect to consider.
If the high THC seeds that you purchase are challenging to grow, your overall experience will suffer — let alone the final yield. In other words, you must choose high THC seeds that match your skill level.
Terpenes make the world-go-round.
Nobody enjoys bland weed that doesn’t smell or taste like anything. Therefore, you must choose high THC seeds that contain a unique terpene profile.
Uniqueness and Personal Preference
Whether it’s for bragging rights or because it’s a personal choice — there’s nothing like growing high THC seeds that no one else has.
You must understand what you want in a cannabis seed with high THC potential.
Value for Money and Effort
Ultimately, you must decide if the high THC seeds in your shopping cart are worth your money, time, and effort.
