Visited my mother this afternoon (of course). Turns out she decided to plant the baby greens kit I brokered for her on an Aerogarden Outlet deal (new bulbs + mesclun + baby greens kits, $32 shipped). That was April 25th.
Now 2 weeks later, they're all growing fine, and she says she eats a clump of them every day and loves them. (Yeah, she's not big on reading kit instructions.
But then, both of my baby greens pods simply died.)
She has her Aerogarden Classic (Christmas present from my sister and me, Dec'07) in a southwest-facing sunny window bay, and has the lights set to go off at 8 am, so they get about 24 hours light. She tends to let the reservoir get very low (maybe until a warning light comes on) before adding plain old tapwater. And they thrive for her.
We live in the same town, ~2 miles apart. When it leaves the reservoir, it's the same water... Though mine seems better lately, after a water main broke this winter upstream from me - twice.
LOL, stonecold! Sad but true, too often, huh? A lot of my plants would probably benefit from being picked at less. 
Twenty four hours light... Your mum knows how to grow!
This actually works quite well with salad greens - they are not effected by this extreme lighting, they grow better, but, will not last as long...
Yap, happen way too often to my garden back home in Singapore.
Hope I have better luck here... :p

The power of neglect? :p
