Mold Resistant Strains | Bud Rot & Botrytis in Weed

What is this black and blue bud mold? Help!

For all growers of cannabis, black and blue mold otherwise known as botrytis is a disastrous problem. Thankfully, botrytis can be stopped and killed. Botrytis is actually fungi that feeds on the moist ripe flowers of flowering cannabis plants. Bud mold will quickly assimilate and grow throughout the entire flowering bud plant. This unfortunate circumstance is a reality for many herb cultivators growing plants in wet humid climates, such as the sub-tropics and tropics, as well as the wet and foggy coastlines of the continental United States.

Botrytis bud mold is found in a wide variety of plants, including cannabis. This includes but is not limited to:  cabbages, strawberries, grapes, apples, and oranges. This common mold botrytis is likely growing in your kitchen right now! Botrytis is as common as it’s dreaded cousin:  powdery mildew. Both botrytis bud mold and powdery mildew causes havoc on garden plants, especially on cannabis.

Now there are many varieties of cannabis, and some are more susceptible to bud mold botrytis than others. Generally speaking, spongy-textured buds that absorb moisture tend to be the most susceptible to botrytis bud mold. Dense buds can often wick moisture instead of absorbing it, although too much moisture and water will eventually penetrate. The dense plants have a low oxygen environment anyways, which is perfect for mold growth. On the other hand, spongy-textured bud flowers tend to absorb moisture more, giving the mold disease plenty of the moisture that it needs.

So, what’s the answer?
