We’ve written quite a bit about how mold and bud rot can infest your cannabis plants, but we thought it might be helpful to provide a list of some mold-resistant strains! Good genetics help protect weed plants from bud rot and other molds.
No more marijuana mold or bud rot!
List of Mold-Resistant Cannabis Strains
Strains for Indoors
Although nothing can fix bad growing practices, some strains are more resilient towards mold than others. If you’re growing in a smaller space, or if you live in a part of the world that gets very humid, it can’t hurt to get a more mold-resistant strain!
Here are some strains that are mold-resistant and suitable for being grown indoors:
- Purple Ghost Candy – This plant grew bigger than expected, but it was able to stay close to the super powerful LED grow light without any issues, so its bigness only increased the yields. This strain never seems to suffer from bud rot or mold, despite the big yields, even when it attacks other plants right next to it. The buds are also extremely potent. Highly recommended as a mold-resistant cannabis strain.
- Moby Dick – Easy to grow, mold-resistant, and potent. Smells a bit like peppermint but has also been described as having an old-school skunky flavor similar to popular sativa buds from the early 90s. Great yields, too!
- Sweet Tooth -This strain is a personal favorite. It has a sweet flavor/taste that is reminiscent of chocolate, and the effects are powerful. As a bonus, it is mold-resistant from its Hawaiian roots
- Glookies strain is resistant to mold and poor environmental conditions. This one survived excessive heat and high humidity to produce great yields with strong bud effects.

Strains For Outdoors
Although definitely not foolproof, it can’t hurt to get a more mold-resistant strain if you live in a humid environment, or if you’re an outdoor grower who gets cool wet conditions early in the fall!
Here are some strains that are mold-resistant and suitable for being grown outdoors:
- Blue Venom – A G13 Labs strain that is resistant to mold and produces beautiful bud quality.
- Holland’s Hope – Designed specifically for outdoor growing (and not really suited to indoors), this strain is ready to harvest in late September or early October in the northern hemisphere. This strain has been bred for bud appearance, potency, yields, and overall weather resistance. Plants get 3-7 feet tall on average and produce a “knock-down” and “euphoric stone” effect that’s been honed for over three decades, with unique effects that are difficult to find with indoor strains. The buds are very mold-resistant and tend to get very fat. Buds often take on purple hues as they approach harvest.
- Frisian Dew – A popular strain because about half of the plants grow buds that turn an incredible, vibrant purple (the other half of plants grow green buds but still beautiful and the effects are just as good). This strain tends to grow the most purple buds if plants in the flowering stage are exposed to very sunny weather with many hours of direct sunlight each day. Another way to help increase the overall amount of purple is to ensure plants get cool temperatures at night. Essentially, a big fluctuation in temperature between day and night enhances purpling. This strain is very well suited to outdoor growing, even in northern climates, and is especially resistant to mold.
The plant in the middle with the dark purple buds is Frisian Dew.
