Beetroot after 12 weeks

So here are the Alto F1 Beetroots after 12 weeks. I picked another few of the plants, and even though above the soil they looked promising, there was very little below the soil.

I've today planted a new variety of beetroot, being Cylindra Beetroot.  Like the Alto F1 variety, the Cylindra should produce long cylindrical roots, but hopefully the roots will turn out to be bigger than the F1.  I'll be keeping track of the progress.
