tomatoes with pic

do i need to do anything with these now or are they ok growing on in what they are in for now.
im not putting them in final pots yets as not built the greenhouse yet!
but can do if they NEED to be in bigger pots now.
i can just see the tip of roots at the bottom of some pots now.
varieties are gold digger, money maker and red alert
many thanks

i dont anticipate the greenhouse being build for another few weeks yet.
these toms are in the house and will be untill they go in unheated greenhouse prob in june- just had hail storm 10 mins ago!
i was going to put them in bigger pots with no bottoms and sit the pots inside a growbag or just put them in bigger still pots like the bigger poundshop ones.not sure yet. but not in the ground.
