problem with Flow

[Stan]

I don't understand exactly what you are saying. Are you trying to build something like a aeroponic cloner like this?

If yes you will need rockwool in the small net pot then you would need to put hydroton to top off the net pot. The reason for hydroton is to prevent algae buildup from the lights or if growing outdoors the sun. With spinach and lettuce you can grow them to full size in a very large aeroponic cloner. With peppers you would need 2 totes on top of each other. The bottom would hold the nutrients the top would hold the roots and sprayers. Here's a pic of some pepper plant roots in an aeroponic tote.

And some roots can get really long.

If you are going with the aeroponic setup and you plan on growing lettuce or peppers the full cycle from germination, growth, reproduction, pollination, and seed spreading stages you will need to spread the plants further apart compared to the picture I posted earlier. With lettuce like romaine you could get away with growing in every 2 inch net pot but butterhead or lceberg type lettuce would have to be grown in every other net pot as they are wider. Same goes for pepper plants they need more room so every other net pot you could get away with.
