well i have a regular old terrarium, used for germination... plastic with a clear removable top. bottom plastic also. filled with germination mixture. the top has 3 holes, triangular arrangement. wondering if it would work better if i plugged the holes... holes are hardly large enough to get a pen tip in. it seems the terrarium stays pretty humid, judging by the condensation. holes good bad or nuetral? maybe not a very important question, but the little things really help right?
