Keith,

The stuff you do with rainwater is exactly correct with RO water.

Pay particular to the pH and buffering.

Hi All !
I am concidering a Ro unit ,i have looked at the First Rays info
etc
..I know you can buy ready made fertilizer designed for use with pure
water,but don`t think this type of feed is available in the UK .

I add fertilizer ,and added Mg & Cal to my rain water so would this
suit RO
or is this not enough .
Any input appreciatted.
Regards Keith
