Week 1: Tower Garden plant growth

My seedlings seem to have adjusted well after 1 week in the Tower Garden and I can now officially call them "plants".  I haven't noticed any signs of transplant shock and there is noticeable growth daily.  I've checked the pH every other day (lowered it twice- trying to keep at 6.0) and set the pump timer for 15 minutes on and 15 minutes off.  The water level has barely dropped and I try and rotate the Tower and Base 1/4 turn each direction daily to equalize the amount of direct sun.  I suspect this will not be necessary once the plants grow a bit more.  Below is a photo I took yesterday...quite impressive isn't it?
