sup city, At what point would you say that a seedling is stretching to do lack of light or what ever may cause it? in terms of length of the stem i guess. im refering to like a plant less then a week old.
about an inch, im not concerned yet. im asking more for a reference so that i can spot the problem if it happens
one inch is not bad for a seedling. Just make sure you light is not an Incandescent light. Make sure your Flourescent that your using is almost touching the seedling, anything further away will cause it to stretch.
