Nicotiana growth conditions

We grow our plants in growth chambers at 16 h days, 28 C day temp, 23 C 
night. Many of the tobacco varieties used today are day neutral, meaning
daylength won't affect flowering. We grow them hydroponically with our
Gibeaut's solution (see http://www.ag.unr.edu/cramer/hydroponic.html)
