Aerogarden Root Problem!

I have 2 plants about 6 weeks old. They are now about 16-18 inches tall. The first two weeks the plants were in soil, then I got an aerogarden and moved them there and they are doing well but one of them was not put in the foam starter correctly from the beginning. The stem of the plant goes all the way through the foam piece and out the bottom are the roots, this is causing the plant to occasionally tip over. As opposed to the roots growing through the foam and out the bottom and being a stable plant. Any help on what to do with this plant so it will support weight of the bud?

It looks like this vvv

More sponges? Buy some sterile sponges from the store and slice them, wrap slices around the stem but inside the aerogrow pod?
my 2-3cents

Use plant yoyos - I have them supporting several 4' plants in 2" netpots (not in a Aerogarden). They're about $2 at a grow store.

^ are you talking about those things that hold name tags and security cards and pin them to your shirt or belt?
