when do I transplant the seedlings to the hydroponics system

[system]

I am new to hydroponics and have a general question.

When do you transplant the seedlings to the hydroponics system. In general I am talking about the 11 plant system that you have plans for. Also what is used to support the plant?

Thanks.

When they are well rooted wash off the dirt or vermiculite . Place in a half cup of rocks. Fill the rest of the cup with rocks.
