About the frogs? Leave them be. They will be eating the bugs. I have frogs and newts in my greenhouse and as far as i am concerned the more the merrier.

 

Too late to do much this year, but try increasing ventilation next year as blight develops in damp conditions. This summer has been so wet that even outdoor crops have been affected and the higher humidity in tunnels just adds to the problem. It's been very difficult to maintain and regulate optimum growing conditions under cover this year.
I wouldn't worry about frogs I doubt if they'll scoff too much of your produce, though they might reduce the slug and snail population.

 

May I ask why you are growing tatties in your poly tunnel?

I am thinking of getting one and curious how much earier the crop is ready

Sandy, I would advise against growing tomatoes with potatoes. Grow them but keep them seperate, tomatoes in the polytunnel potatoes outside as far away from the toms as possible. I would also suggest you treat the soil with Armillatox or Jeyes Fluid after having blight in the tunnel. David.
