I've been using batterywater for my seedlings and plants, but I have been recommended to try to collect rainwater. If I'm going to Do that, I have to do it through my downpipes. No problem so far, but it hit me, do the water collect minerals and such when flowing through the down pipes made of metal? If that is the case my dead friends will die.
Anyone that knows or have tried ?
A bit off topic I know, but I have some water I don't know if I can use.
* My iPad "fixed" the subject for me from rainwater to raindance which is kinda wierd, but I did t notice until I had posted it.
