Can anyone "hand on heart' say:

I was new on the plot this new and a newbie when it comes to greenhouses.
I delayed some plants as I was going on holiday and would not be able to water each day, happened to mention it to my neighbours on the plot and they have very kindly watered plants when I was away! What a great place an allotment is! Really must try and rig up some drip system from guttering next year though!

we have two large greenhouses used throughout the summer season we usually put  plants that are not to frost hardy in the greenhouses and cover with fleece over the winter period

never thought about using the tunnel but have decided to put spring greens and cauliflowers and broad beans to overwinter in pots to plant out in the spring he says confidently

regarding  the greenhouse cleaning  i must admit to be lethargic as far as that goes but your rite a good clean with Jay's and sulphur candle that we must do as you say in January good sound advise 

Yes can honestly say ours is in use.  During the winter its spring cabbage, kohl rabi, lettuce, pak choi, spinach, chard, parsley, coriander and caulies which head up in March.  Also grow komatsuma and red russian kale and overwinter spring onions.  During the summer its sweetcorn, courgettes, aubergines, celery, celeriac, kohl rabi, pak choi, spinach, peppers, butternut squash, early and late calabrese, strawberries,lettuce, parsley, coriander, dill,  early beetroot and early new potatoes (usually dig the first on May day) and carrots.  I should say its a big one.  Twin span 56ft by 45ft divided into four bed rotation.

We're also retired so hubby spends all day either in the veggie garden or tunnel, depending on the weather.  Using a tunnel in winter is worth its weight in gold, especially with veg prices rising all the time.
