What about watering? I assume they do not drain? Do you just have to be more careful not to over water?

I use to use those bags before i went to hydro. They have drain holes built in. I preferred actual pots but the bags were so cheap and readily available they were hard to beat under the circumstances at the time. However once i had the time and started hitting up local nurseries for cheap used pots, i found they were willing to make me super deals on them.
