Ok so I was struggling to get my plants to grow!hadnt grew in 2 weeks and was using distilled water. Now I'm a newbie kinda. Tried a few times but got nowhere. So this is the question what should the ppm be in distilled water??? Reason I ask is I finally bought a ppm meter. Cheap from eBay but hopefully close enough. So decided just to test ppm off my distilled water I was buying at 7 dollars for 4 litres each time!! My ppm was 540! I'm really not sure but is this not high? Also I thought ppm in distilled water is meanta b 000?? I think this is y my seedlings won't grow past 1 bloody inch!! Am I on to something it am I still not there?? Also decided to test some rain water and ppm was 004! I'm thinkin just use this but am I right?? Sent from my iPhone using Grasscity Forum
