Challenges of growing strains outdoors in a hot, humid climate

If you live in a hot climate, many strains may not be able to cope with the sweltering summer conditions. Cannabis generally flourishes at temperatures well under 30ºC, thriving in around the mid to early 20s. Too hot and your plant can undergo what’s known as heat stress. This general condition can cause a whole range of stultifying mishaps, from root rot to dead leaves. If a plant undergoes some form of heat stress, it won’t be able to grow sufficiently. The earliest stages may see super-slow seedling growth or leaves that grow withered and pale from the beginning. Getting your plant just past the seedling stage can be difficult in these dangerously hot conditions. Things to look out for include spotted leaves and burnt exteriors that brown or wilt, and foxtail buds during the flowering stage with extra pistil coverage (that are white rather than colorful).

Just as heat can be devastating for plants, humidity is dangerous too. The primary issue with increased air moisture is the promotion of mold, mildew, and pests. Many strains require low room humidity percentages, particularly during the flowering phase, to promote healthy and potent bud production. Too much moisture and you risk damaging your plant at its most crucial stage! What’s more, as your plant takes in more water from the environment, it draws in less from the nutrient-rich soil. The transpiration process slows down, leading to a wide variety of damaging issues. Plants will wilt, stunt, and suffer if they are not designed to withstand these high humidity levels.

Luckily, there are plenty of strains that have adapted to higher temperatures and humid environments. Most of these are Sativa-dominant strains, but there are a whole host of hybrids that are perfect too. Sativa strains originated in East Asia and have a strong tradition of cultivation across South East Asia and Central and South America. As such, they are naturally resilient to tropical and subtropical conditions. It’s in their DNA. There are even specific tropical Sativa varieties that flourished across Central Africa and Latin America. Indicas, by contrast, originate in mountainous Central Asia and require dry conditions to flourish. So, if you live in a hot and humid climate and are in search of the perfect outdoor strain, here are the top 10 options.
