Indica or Sativa? Which Has Highest THC Seeds?

Both Sativa and Indica plants can blossom heavy with high THC content seeds and flowers. The strains that give you a dense and carrying-out stone-effect are usually Indica. Energetic and creative high-rush is generally brought forth by Sativa strains. Yet, over the past 40 years, there have been so many hybrids that there is no longer pure Indica or pure Sativa on the market. There are only varieties with dominant Indica genes and there are varieties with dominant Sativa genes. At the same time, there are such crossbreeds where both parameters are balanced to be 50/50.

In addition, each buyer will find such a grade that will fully satisfy it in all respects. You can also choose among plants with the fastest flowering cycle or such weed bushes that will be compact enough for home growing.
