Researchers Find Unknown Chemical in Drinking Water

[Orange's Greenhouse]

If there’s not much in it between distilled and ro why are so many growers using ro? Not seen any using distilled.
The distilled seems cheaper and less plastic, is it the electric running cost or capacity that puts people off?

Distilling is much more expensive to run. It's also much slower and you waste more water for cooling.

Been trying to work it out, roughly 10p per litre electric plus cost of machine with average 2 year life expectancy is about £3.50 a day for 5 litres or £4 per day for 10 litres which is maximum capacity after allowing for cooling and cleaning.

Getting the ro filter, much cheaper than distilled. Not so much the electric cost as the replacement of the whole machine every two years vs hopefully just the filter every now a then with ro.

Hang on, that can’t be right.
Not sure how I got that so wrong, it’s about 35p per day machine replacement cost and then 10p per litre so probably 85p per day for 5 litre’s. I’m back to being undecided. Still much cheaper for ro I guess.
