Potato and carrots.

So I planted my
potatoes and carrots in their plastic containers on 15th March and nothing is showing any signs of growing yet. 
How long should I expect to wait. Many thanks.

    Do you mean the plastic boxes besides the veg beds? If you do they are unsuitable for potatoes as the light will get to the tubers making them green and poisonous. Also it's still a little cold outside, my potatoes are still chitting in the conservatory not going out till the weekend. It is still early to see any growth outside.

    I’ve seen loads of people growing them in plasric
    containers outside?

    The problem isn't that they're plastic, it's that they're transparent (I grow mine in halves of old water butts and it works fine).

    Surely the tubers would have to be in direct sunlight?

    No.  Complete darkness is what they need or they go green.  The foliage needs sunlight to photosynthesise but there should be no light on the tubers.

    Then they should be OK altho I don't see much room for earthing up so make sure you keep an eye out further down the line and pour compost or soil over any exposed potatoes.

    Probably about another 14 inches for earthing up. Hopefully that’s enough.

    Yes.
