Tall seedlings

Nice job, they will be fine. If you are concerned, you could always top your pots up with more soil so that it buries a portion of the stems, thus providing a bit more support. Over time your plant will send out roots from the buried portion of stem. Try not to have your fan blowing directly on your seedlings at this age/size, far better to have the fan blowing against a wall at 45-60 upward degree angle, so that the air goes around in a circle - off one wall, off the roof, off the opposite wall then back down to your babies. This will create good air CIRCulation without buffeting your fragile seedlings. You could just leave them too, either way they will grow normally. Hope this helps.... Organoman.
