i have been feeding my plants with regular distilled water for about 3 weeks know and just ran out yesterday.Its a bitch because just 1 gallon of water is just for one feeding for my 4 plants and its also a pain always going to the store.The other day it it was raining all day long so i decided to put a jug outside to fill it up with water and see if it will benifit my plants.The next morning i tested the water with my ppm pen and in amazement it was 0ppm so im guessing thats good but dont know for certain.Is this water the next best thing instead of distilled and has anyone had any problems with rainwater?

dude, rainwater is the best water you can use for plants....thinkabout it...all plants are living outside and is fed by what? anyway, if you dont want to keep buying distilled water just fill up a large bin with water and let it sit for 2-3 days. ohyea rain water is pure..distilled water is just filter and still has shit in it.

thanks bro

so does that mean the ph balance of rain water is a perfect 6.5 or do i still have to adjust it to were i want it.

with rainwater is depends where you live as it dissolves stuff in it in its way down to earth.
