Have these brassicas grown enough for me to plant them in their final growing positions on the plot, or shall I give it a little longer?

Personally I would wait as they look rather small, but then the pic on my iPad is tiny so I may need to go to spec savers too.

I'd say not yet, they need a little more growth on the top before they go into the soil. I like to see mine about twice that size.

As they are in individual peat pots, they can be planted out as there will be no root disturbance.

They will need protection from slugs, and netting if you have a pigeon problem.

I'd leave them a bit longer, as well 

[DD.]

I'd also leave them longer and reduce them to one per pot.

I'd also leave them longer and reduce them to one per pot.

Is it feasible to divide them into individual pots (they are in peat pots at the moment), or should I just prick out the weakest ones? Trouble is in some pots both seedlings are about the same vigor and it seems a shame to kill one of them.
