Ok. So, I want a hydro system where I can use a tupperware container, grow 8 plants at a time I have the BC 3 part system of nutrients. I also have some super thrive.

I plan on getting a 10 in deep tupperware container that is 3 feet long approximately.
Hydrotron media,
rockwool seed starters,
a 2 port air pump I already have one airpump I've been using in an unsuccessful attempt in the aerogarden.
3 12 or 14 in (the largest that will fit) in the container airstones,
and
getting 3 inch pots.

What am I missing? Is the container deep enough? Will the roots get tangled? Should I get a water pump too?

Do I need any other nutes besides the 3 part BC system? Their feeding schedule online says you need like 12 things, do you really? Or is the three part system enough?

I want to make a system that will work the first time. My aerogarden experiment has left me with 8 seeds, so if this doesn't produce, I have to reorder seeds and have nothing to show for my last order.

I plan on getting as many pieces and parts as I can from lowes, the rest from a hydro store that is a bit of a drive from here but isn't too far away. Please, be nice in your criticism but tell me every little place I could do better so I can make the best system possible. Please please help me out on this one. I want to start building soon. My birthday gift certificate from lowes should be in the mail tomorrow.
