Can anyone tell me how much is recommended per litre or 10 litres of water?

Rightly or wrongly, I use 120 grams of powder in 22 gallons ~ 100 litres in the motorhiome and flush the pipes twice with 2 full tanks of fresh water. The teaspoon measure is ambiguous... heaped, not heaped and everything ion between.!!

Will this clean water in a water Rowing machine?

This product is meant to clean drinking water systems. I can't think that you would drink the water from a rowing machine, so I'd imagine some diluted domestic bleach will work out considerably cheaper. I've use it to clean a drinking water supply pipe in a trailer tent, which develops black mould during winter storage. It comes out completely clean following the directions on the pack. So, I guess it would work for you, but would be an expensive option.

I have to carry all water over the road to my motorhome, if not used for drinking, can I use without flushing through?

i always flush out. you could do this on site on arrival

If I put it in a rainwater but is it ok to put on plants later?

I am not a chemist but as I said before I think these tablets contain sodium hypo chlorate which sounds a bit close to sodium chlorate (weed killer) ! I am it sure quite why you would want to sterilise a water butt in this way. Why not just drain it and give it a good scrub or use a fishpond cleaner.
