Plastic empty cooking oil food buckets/drums (Ashburton CR0)

I want to use these for growing vegetables using the Kratky system, please. They need to be food-grade plastic, which means they have the no. 2 in a little triangle embossed on the base. Around 10-30 litres would be very useful, ideally with lids, but I'm open to anything going spare. I'm hoping someone has a few that they thought were a bit too good to go in the recycling. Thanks in advance.
