I grow Long White, started in the propagator early March, grown on in the conservatory - I ate the first fruit, admittedly not very long yet, a fortnight ago. This regime gets me early cukes, but they are not the most flavourful, so this year I did some Telegraph the same. The most advanced has a fruit about 9 inches long ....I'm hoping that will be more cucumbery than the white-skinned ones. The packet on those claims no need to peel, but I find it too chewy.
