well first, I don't use soil I use coco. only use soil in 3 pots as a control group.forget the ro water if your growing in soil. Just let your tap water sit out for 24 hours before using this will bring the ph down and the chlorine will evaporate. Tap water has beneficial minerals in it. RO water takes these out. RO water will work but why pay more for something not as good as your tap at home?
second and more important - while the tap water might have some beneficial minerals, I don't know what they are - and so they are counterproductive for me, if I need to water seedlings, or want to flush my medium.
I live in an area of very hard water, ppm is about 600, that is very high. it may not prove detrimental to some plants, but for an inexperienced grower such as myself this can be critical don't you think?
