Are Aerogarden grown plants safe?

[Accidental Sulcata Owner]

So I grow mustard in my aerogarden already. I was wondering if this is safe to share with my new sulcata. You add plant food once every couple weeks...

They also sell a "grow anything" little empty pod that you add your own seeds to, so if this is safe I figured that I could fill up the rest of the pod spaces with seeds from the food list from Tom's threads...

Yes, mustard is safe (and delicious!) Our little sulcata didn't love it, but he did eat it, he has so many choices he can afford to be picky.
I'm sure food from the Aerogarden is safe, but I would check into what kinds of plant food you use. If you could find one that is organic or at least designed for consumable crops it would be safer.
