I currently have 7 seedlings growing (only 2 weeks old). I decided it was a good idea to reuse empty 60s of rum as pots. I sterilized them and planted my seeds. After doing a little more reading on growing it seems as if this may not have been a great idea. Should I try to find some larger pots or will the 60s be large enough that they don't cause serious problems with the plants. I may end up planting them outside anyway but since the weather's been kinda cold recently I can't do it yet.
