I see a lot if people saying they use it for nocing which when doing jars so did I and it was amazing. I must say I love this thing because I noticed a small cluster of green growing on a quarter sized spot of uncolonized sub. 30 seconds on the green mold twice and it saved my bulk sub. 35 bucks in the end saved my 8lb cake!
I believe it worked correctly. I'm not too sure how I can test to make sure it works, but I have had great colonization with no contamination sited so far. The instructions given with the grow kit were very helpful.
thought I'd make the investment to insure a good grow, My hunch was right when i was able to kill mold starting in one of my injection spots through the glass!! Awesome! Saved that Jar
It operates perfectly and used in conjunction with other sterilization methods I still have no contamination problems.
I really like the UV light. It feels like a quality product and anything that can help success rate is worth the money. I’m happy with my UV light purchase.
