Beetroot in paper pots

I have started some beetroot seeds in paper pots indoors (about 12 in total). I understand that each seed is actually a collection of seeds.

Each pot now has between 3-4 seedlings at 2" tall. Do these need to be thinnned or not? I seem to remember reading somewhere that they are ok left and will eventually push each other apart as the root develops. But they look so over-crowded!

Many thanks in advance

ps. did a quick search for previous posts in this but couldn't find exact question answered

Ah - ok - that's interesting. Thanks.

Hang on though - the whole point of me using the paper pots was to avoid root disturbance! I did a separate batch earlier in the year that were in plastic pots and I transplanted into the ground. I wanted to do the opposite with these and compare them so I know what works best next year.

Ok - so it's a matter of choice in that case! Maybe I'll try a bit of both this year and then see what works best!

We tend to use beetroot mainly for making soup so maybe I'd prefer the larger crop?!

I get you no probs. Hadn't thought of things that way, so thanks, it does make sense.
