Mold Resistant Cannabis Seeds


When it comes to growing cannabis, not everything is straight forward and sometimes things can go wrong! While this is the case, you don’t want your months of hard work to be ruined by a pest infestation or by gathering mold in the final weeks of the grow cycle. This can be minimized by closely controlling the temperature and humidity in the grow space and selecting a cannabis strain resistant to mold. All of the strains listed in this collection have a high resistance to mold and are suitable for growers with humid gardens.

All 3 seeds germinated within 12h! A day after I planted them in pots with coco and soil. Used sunlight during the day and 45W Leds after 7 pm when it was getting dark. They were growing mad during vegetation gaining almost 40% of their green mass each day. After 18 days I put them outside under 10h of direct sunlight. Added banana peels, chicken manure and drainage. They got adjusted within a week and then started shooting up again. But then the temperature dropped to -2C outside which I didn’t expect at all. I thought they’d die but my Hazes all survived! In fact, they kept thriving as if nothing happened! They reached 2.5m in height with lots of side branches. I had to chop them earlier than I expected but I am very satisfied with what I got! 1.She’s a fast grower2. Even her leaves give a strong effect!3. Resistant to low temps and diseases - no plagues at allShe’s a bit slow during flowering but I guess that’s because of bad weather - in warmer climate she’ll do better. Happy growing and harvesting to ya all!!!

Why Buy Mold Resistant Cannabis Seeds?

Mold spores are constantly present in the air around us and it is difficult to purify air to the extent that you don’t have to worry about them. However, the risk of mold growth in your tent can be minimized by ensuring the appropriate:

  • Relative Humidity (RH)
  • Air Circulation.
  • Air Extraction.

Cannabis Seeds With High Mold Resistance

Modern hybrid photoperiod cannabis strains are designed with mold resistance in mind. In addition to having a higher stress tolerance, they can tolerate greater amounts of stress, both in the vegetative and flowering period. This means that on the off chance there is a breakout, you will have enough time to deal with and contain the issue. If you want to avoid worrying about this altogether, opt for one of our mold resistant cannabis seeds! These have a high tolerance to humid conditions and tend to have a high resin production which wards off common pests.
