I think you mentioned elsewhere you are growing Thermidrome? That is a softneck, so they are mature sooner than hardnecks anyway. Also they are great keepers, which means you will have garlic for a long time (maybe a year?) if you cure them properly.
That being said, there's nothing to stop you from eating some immature garlic if you have more than you're going to need for a year besides your seed stock for replanting.
Fresh uncured garlic is very juicy and not as strong tasting as a properly cured bulb. But it is totally good to eat all the same, if you won't miss the fully grown one.
Incidentally I am growing some Thermidrome from bulbils which Svalli sent to me.
The plants are very vigorous and I think they will do well here too.
