I am impressed about the idea open source hydroponic agriculture. But I don´t want go to it and than one day realize that I was constantly hurting earth.
Of course in hydroponics we use 90% less water, using LED we produced much less heat etc.etc...but what about nutrients?
1)I mean once you use some nutrient solution you have to change it after some time, right? And what to do with this terrible waste product? In some hydroponic forum I´ve read: „well...just use it to water vegetables in your backyard.
Maybe unless is hydroponic only toy for few people it does´t matter. But in the future? Is soil and ground water going to be full of synthetic nutrient in the future?
2)Is the synthetic made solution (nutrients) only way to feed our plants?
Thanks for answers (discussion),
I really appreciate OpenAG initiative, best regards,
