Ok. Thanks man! If they are as big as half an inch diameter, that would be great. Even you pour too much water, it should dry out on the top soil in few hours. The run off water should come out steadily. Not just dripping out. I would give half an ounce of water around the plant and wait for 12 hours to check for her response. You can use a shot of glass for measurement. Hope this help!I'll have to take them when I get home from work but the drainage holes are basically approx. 5 small circular holes on the bottom.
