I have just erected a 30 by 14 foot polytunnel. I am an experienced general veg gardener but I want to optimise use of the polytunnel. Can anyone suggest a really good book or forum or magazine that is specifically Polytunnel orientated please. Particularly interested in dates for sowing early and sowing late for cropping late  where these differ from greenhouse or open plot practices etc.
Many thanks
