You can find plant food at any gardening store, home improvement store, or even walmart.

Turtle, you should stop encouraging people to purchase supplies on ebay. Ebay cooperates with government (definately U.S., not sure about others) and gives out all the information on who buys what, and even who searches for what. If you buy all your grow supplies on ebay, the gov. could EASILY track you down.

I won't even use a credit card to buy my stuff at a store, because the credit card companies track what you buy. You should always pay in cash to avoid leaving a trace.

Call me paranoid, but I'm just trying to keep everyone safe!

Happy growing,
joe.
