questions about floating raft culture

I'm thinking about growing leafy vegetables in a floating raft system--basically a kiddy pool filled with solution and a styrofoam raft. But I have some questions before I get started and I was wondering if you all could help me with them.

I've read that this system works well for lettuce and some herbs without an aerator so long as the net pots (or styrofoam cups with holes cut in them) are set in the raft so that they only just barely touch the water's surface--no more than 1/8 or 1/4 inch should be submerged.

My questions are:

Would the lettuce grow better with an aerator anyway?

Have any of you grown other leafy vegetables like collards, kale, and chard in a raft system and how did they do for you?

Would scallions or green onions grow well in a raft system?

Would herbs like parsley, cilantro grow well with this system?

Thank you!

Bill
