My grow bag is fully colonized, but it looks contaminated. What should I do? 

If you notice that your grow bag is fully colonized but appears to be contaminated, it's essential to take immediate action to prevent any further spread of contamination. While contamination can occur during the colonization process, it can also develop due to poor growing conditions or other factors.


To determine if the blue substance on your grow bag is contamination, you should isolate the bag from your other grow bags and carefully inspect it. If you see any fuzzy growth, discoloration, or an unpleasant odor, then it's likely contaminated. In such cases, it's best to discard the bag to prevent the contamination from spreading to other bags.


However, if you're unsure whether the blue substance is contamination or not, you can perform a simple test to confirm. Using a sterile q-tip, gently swab the blue substance and try to remove it. If it comes off easily, then it's likely contamination. On the other hand, if the blue substance is firmly attached and does not come off, it's likely bruising, which is a common occurrence during the colonization process.


If you determine that your grow bag is contaminated, it's crucial to take steps to prevent any further spread of contamination. Make sure to clean and sanitize any equipment or surfaces that came in contact with the contaminated bag. Additionally, it's essential to take preventive measures, such as maintaining proper humidity and temperature levels, to minimize the risk of contamination in future grow bags.


In conclusion, it's vital to keep a close eye on your grow bags and take immediate action if you suspect contamination. By identifying and addressing contamination early, you can minimize the risk of contamination spread and ensure a successful growing experience.
