I'm still fairly inexperienced and am now facing a new problem that i did not plan on seeing. I have followed sanitary precautions in preparing my terrarium and now am having problems with mold growing on the perlite. In my last attempt the mold grew from the perlite on to my cakes and i had to through many of them away before they fruited. Now I am seeing moldy perlite again, i have been trying to kill the mold by carefully pouring peroxide over the area but it seems to be doing no good. Any suggestions???...........
