When growing plants indoors, is mineral water a good supplement?

Question

I know that plants need a certain amount of nutrition from the soil to grow, and that when growing plants indoors, the only nutrition they get is what you give them. I am trying to grow these plants completely organically, with dirt from my backyard, using nothing bought from a store except the vegetables/plants from which I took the seeds. So far I have large sprouts of morning glories and catnip, and small sprouts of tomatoes, green beans, cucumber, and green bell pepper. They seem to be doing very well with a combination of filtered tap water and mineral water, but I want to make sure they don't suddenly die out because they are getting too much or too little of something. The mineral water is bottled still (not carbonated) Italian mineral water. I have southern exposure in the window that they sit in, so sunlight doesn't seem to be a problem. Any tips for growing these through the winter would be greatly appreciated. Thanks!

Answer 1

Filtered water is best. I would not bother with mineral water, you would be better of getting correct supplements for your plants than using mineral water. Speak to your local nursery and they should be able to tell you what you need to add to your soil in the area in which you live. Happy Gardening!

Answer 2

I also have indoor plants. I fill a large bottle with tap water and let it sit for a day or two. But it sounds like you are doing a good job with your plants, so you must be doing the right thing. When you raise your plants in the sunlight it makes them easier to accept it outdoors. Good Luck!

I'd suggest not to waste your money on it and it might be harmful to the plants. Go to any decent store that sells nutrients and purchase a bottle of trace elements with iron..not sure of a brand name but the stuff is so potent that a teaspoon is mixed with a gallon of water...

...I've had my best luck with well water, the chlorine in city H2O is suspect.
