As long as it works, and makes life easier, anything goes, IMHO! ;D I'm just glad my posting has inspired people to have a go and perhaps introduce new ideas along the way. I like this "Fantasy Allotments" lark, far easier and cleaner than the real thing! ;)
Svea, I'm just growing for two as well, though I'm planning to give away any surplus to my friends, neighbours and Rellies. If I happen to get stuff in return, thats up to them, though there could be some booze coming my way as a result!;) I've got a tall freezer and 2 fridge freezer to fall back on, if necessary, so if all goes well may not need to buy any more veg. Just have to wait and see. ;D
