Question

There is brown discharge from the root. Will it slow the growth of the vegetable, and should I clear the discharge?

Community Answer

If the roots are brown from your hydroponic plants, there is something wrong with the water's mix. Check the pH of the water. You want white roots.

Question

Why are they better than garden grown vegetables?

Community Answer

You can control the nutrients that the plant needs and you don’t have the bacteria and fungus that you often get in the soil. There is also less likely to be a need for pesticides.

Question

Do the nutrient containers leach plastic toxins?

Community Answer

They should not, if you buy them from a proper place. If you're concerned, use a plastic food container to grow on a smaller scale.

Question

Can I use city water with a filter?

Community Answer

Yes, unless your city water is very dirty. If you want you, can buy a pH kit to monitor the pH of your water and adjust it accordingly.

Question

Do I put the seeds in water and leave them to germinate, or do I have to transplant the seedlings into the water?

Community Answer

Transplanting the seedlings is the best idea if you are not using a medium to prop up the roots (like coconut fiber or sand).

Question

Why is a green algae growing in the water? Will it hurt the plant?

Community Answer

Green algae grows from being exposed to the sun. It usually doesn't, and may even help the plant, but could get in the way of water flowing to them. Adding foil around exposed areas would prevent algal growth.
