This popped through my letter box on Saturday. I'd completely forgotten I'd entered the competition on the RHS' Grow Your Own Veg website. I'm not happy about the (just about recyclable) plastic packaging though. It contains a 'patented granulate' which soaks up water. The seeds are meant to be at the top, though whether they've stayed that way whilst being conveyed through our postal system remains to be seen - I'll keep you posted (!).
According to the growing instructions, the container should be filled right to the top with water which should be replenished each time the granulate starts getting lighter. It also says helpfully that the Lollo Rosso lettuce is edible and goes with all meals.
