They need more sun and will become more and more leggy without it. Use whatever light source you can. You could probably put them outside during the day. They have a hard time growing when the temps are below 50FView attachment 11661 I have some cucumber seedlings I'm needing some assistance with. They sprouted two days after planting in a seed starting mix placed on a heat mat. Once they sprouted, I pulled them off the mat and put them in the window. They get about 5/6 hours of direct sun through a window with a screen. However, some of them are now two inches long. I have to rotate them frequently because they lean towards the window. Are they leggy? Do I need to remove them from direct light. I have some 6500k bulbs. Would it help to put those over the seedlings? If so, at what distance? Some of the leaves are curling slightly under, lengthwise.
