A lot depends on spectrum. If you use a cool white compact fluorescent or blue leaning florescent bulbs. Anything more blue will keep them shorter. I do mine under a 3k and they stretch pretty well even when I managed to light burn 3 of them. Look at the front 2 on the left and far right front I cooked 3 of em and they stunted for over a week.keep the light closer next time, after they sprout up and the leaves begin opening
and yeah you can bury them when transplanting i just prefer just not to have this problem cause im not sloppy and its easy to avoid it.
