I bought a simple continuous drip system, with 4 4" containers for
plants, in what looks like a home-depot plastic bin.

1. how do i support a large tomatoe plant with this? Its not like i
can stick a stake into the ground here.

2. i added nutrient. How often do i have to add more? Is there some
nutrient meter?

I want to grow big plants -- tomatoes, green peppers! Did I buy the
wrong newbie unit to start with ?

THanks
