So... I believed that rainwater/distilled/reverse osmosis water was critical to raising these plants. But I guess that isn't completely true.
Sometimes when I go to the market to pick up a jug of distilled water, for some reason it's not available, and all that's left on the shelf is filtered or purified water. I would leave and come back some other day.
Is purified or filtered water OK to use?
(I always wondered why people are taking up the distilled water because there have been a few times where specifically distilled water was all gone.)
