seedlings

Think they will be leggy and a little weak..pop them somewhere cooler...not cold and see...you can always pop a couple more seeds in...I had leggy plants last year but got toms off them

When you come to planting out time put them in deep enough so the surrounding soil comes up the stem nearly to the first leaves,the stem will grow small  roots making better plants of them and take away some of that leggy look.

Did I not say that in the previous post?

Yes, you did! But I disagree I would bury them up to the seed leaves, not just part of the stem.

I am a little timid burying Cucumbers and their cousins up to the seed leaves, when pricking out, although I think even for those varieties, which hate having their stems wet, it does not harm, but everything else I can think of I would have no hesitation pricking-out right up to the seed leaves.

And with Tomatoes, and most probably Brassicas too, I would not hesitate to plant them even deeper if the circumstances needed it.

But, for the avoidance of doubt, it is important NOT to deep-plant things unless you know its OK for that type of plant. Its the most common cause of death for hedging plants and trees when they are planted deeper than the "soil line" that they were planted to before being planted-out
