It won't affect the stem at all if you don't go past the cotyledons. I usually let my seedlings grow about that big before the first transplant, and almost always end up topping off with more soil to support the stem and keep the plants short.

No sweat, it's not too late. :thumbsup:
Mr. Clandestine Reviewed by Mr. Clandestine on . Too late to bury up to the cotyledons? Hi cancom! It's been a while since I've posted. I have gotten on with things quietly on my own until now and I could use a little help. I got busy/lazy and my plants have stretched a little and when I re-potted them I didn't put in quite enough soil. I wanted to simply place more soil on top, perhaps nearer to the cotyledons. However, the stems are hardening and they are green, green = chlorophyll and I don't want to rot the stem. I'd prefer not to have all this "wasted space" of stem below Rating: 5
