How Interesting, Is it possible that other factors like gravity play any part... I ask because i have a number of worsleya seedlings in my shower recess, " Yes it is a pain to move them every time i have a shower " They are in the south - west corner of the bathroom.. Its the only place i have been able to keep them safe & after loosing the first batch to drowning while floating, from floor movement breaking the surface tension of the water & the second to rot from contaminated sand, now its perlite only, & 100% success rate.. What i find very interesting is, there is a wall to the east & to the south, with no windows, only a small window to the north covered by a thick bush so almost no light gets in at all & the only sunlight they can get is from the west. But in the mornings, especially on very hot days when the house has been locked up & reaches well over 45* celsius during the day, they have a tendency to be facing east in by morning, but it is always dark in that corner..

It may do little or no harm to induce symmetry in, say, an African Violet for aesthetic reasons, but in general it is best to allow plants to grow to face the light as they please. This maximizes their ability to photosynthesize.
