@TommyRan The link can't be accessed from Sweden, but I think I know what kind of tub you mean. They sell them at the same place where I got the box and they are considerably cheaper than any other buckets, but it says explicitly that they should not be used for any plants meant for consumption, so I didn't get one. Of course, I don't intend to eat any part of the Adeniums, but I might use the same soil mix for other plants, so I'd rather be safe than sorry. Lining one of those tubs with a food safe plastic sack might work, though. Plus the sack could be sealed for storage to prevent drying out and contamination. That would be an inexpensive option.
@Murky I've split blocks with the band saw before, but my garage is snowed in.
