As the cannabis industry continues to evolve, new strains are being bred with higher and higher THC levels. In 2023, some of the highest THC strains available will likely include:

• Godfather OG: This strain is a cross between OG Kush and Alpha OG, known for its high THC levels of up to 34% and sedative effects.

It's worth noting that these THC levels are based on lab testing and may vary depending on growing conditions and genetics. When it comes to growing these strains, it's important to provide the plants with the proper growing conditions, such as the right amount of light, nutrients, and temperature. It's also important to make sure that the plants have enough space to grow, as these strains can get quite tall.

It's also important to note that the yield and potency may vary depending on the growing conditions and the genetics of the plant. A great way to ensure a high yield is to choose high-quality genetics, and it's a good idea to purchase seeds from reputable seed banks.

Overall, the highest THC strains of 2023 will likely be known for their high THC levels and powerful effects. These strains can offer a balance of indica and sativa effects, but with a stronger punch. They are great for experienced cannabis users who are looking for a strong and potent high.
