- Yes, I would.

- I thought I'd posted a reply to the net, but I must have just sent
- private email - sorry.
-
- I agree with you about 'sacrificing' water for mineral uptake - we tend
- to dwell on water use efficiency as if water is *allways* in short
- supply. One thing people tend to forget about is winter drought though
- (when the available water is frozen).
-
- It isn't in short supply here, today, in Scotland ;-)
