Well heres my plan. In spring time im going to have a lot of plants outside my room on the balcony. I would like to grow vegetables etc. I plan on using aquarium water to use on the plants. I thought this would be a good idea since aquarium plants use nitrates in the water, why wont gardening plants use nitrates? Would this work as a fertelizer/water or just water.

By the time the plant uses the nitrates for food, the biproduct would be non toxic for humans in the situation you are describing. I use aquarium water to grow awesome tomatoes, spices, lettuce, and other veggies. I also use my pond water for watering my veggie garden a few times/month. It's the best fertilizer you could ask for, and its free!
Happy Gardening!
