The radish's I picked are the white icicle kind so maybe an inch to 2 inches, I think. I'll have to double check the packet. Kat, I'm not sure how you would do this 'greenhouse' effect with the top of the jug, could you explain further? Weedwhacker, I can certainly keep a photo log of the process, it's all new to me too. Thanks for the idea and your interest.
