Hi all ... this is a question for the experts really
I know that the following is not to be used
Bottled Mineral Water and Tap Water contain far to many chemicalís and mineralís that the plant does not like.
River Water to be avoided due to chemicals and pesticides that may run into the water.
Save to use and by far the best is Rain Water.
Now the other option is RO (Reverse Osmosis)
So how far does one have to filter to 50, 3, 1, 0.1nm
Is there any other methods of obtaining good water for this plants that someone can add that I have not already listed.
Many thanks Noddy
