Need Help

Hi guys
I've decided that its time to upscale my potato growing as i haven't got the ground space i've opted for a different approach. Trying to find some juice syrup barrels so if anybody knows of a good supplier or any ideas where to try. Only need 2 as i'm growing 4 varieties next season. Going to cut them in half drill several holes in the bottom and start to fill with compost. Did toy witht he idea of having 4 of them, then remembered that i've got the purchase a lot of compost bit expensive that one.

Terry
PS any help is gladly received.
