We did not find the directions when we opened the box and removed the wand. After installing batteries we could not get it to work. Once we found the directions everything was simple. Great piece of equipment and if you plan on growing mushrooms or just keeping your living area free of harmful bacteria you won't be sorry. Great product! Great price!

This is what you need to have peace of mind in these new times. This works as it should I'm going to making Spore syringe off of print with it today that way I don't have to have a flow Hood. This thing works that's where they use them in hospitals it's the same wavelength that they use in hospitals here in the states

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
