Tips for feeding Tomato plants?

[MarkPelican]

Do you have any experience of potatoes in them?

Not in MFBs, I've grown them in potato bags in the past without much success and eventually decided that its cheaper to buy potatoes from the supermarket., can't tell the difference in taste and we got quite a lot of blight on the allotment so storage was a problem.

Harvested a couple of the MFB potato pots today. First time growing them in smaller pots. Got just about 1kg of Charlottes from each pot. Pretty happy with that.
