Kath, to grow early in the greenhouse, but not necessarily an early variety ,have you considered Pervaya Lyubov ( First Love) which for the past several years or so has been one of THE most popular varieties from my seed offers as well as from SSE requests?
About 75 days, indet, PL , round pink, and almost everyone speaks of the sweet/tangy taste. Seeds originally from Andrey. But perhaps you've already grow it?
Yes, I know I'm an enabler, so deal with it.
