Hello guys and gals I've got a question for ya. I have an old aero garden that was given to me as a gift. I was hoping to use it this winter for maybe some fresh herbs or tomatoes. The problem I'm faced with is having to buy the official aero-garden plant food. Those pills you drop into the water to feed the plant. I know that there are some other liquid forms of hydro plant food out there. But I was hoping someone out there could tell me there is a simple way to make your own. So does anyone avoid buying store bought plant food for their hydro systems by making their own?
I was thinking maybe a compost tea any ideas would be appreciated.
