Polytunnel in shade

Evening all,

My parents-in-law have just erected a polytunnel that is 25 foot long, but it only gets mottled sunshine throughout the day, and will be in shade for about 5-7 hours a day.

Are they likely to be able to grow anything. I have said no, but they are convinced they know best.

Leafy greens will probably be OK, but then you really don't need a polytunnel to grow them.

I'd agree with Totty that most of the stuff you would look to grow undercover - tomatoes, peppers, aubergines and the like - will get leggy and drawn through lack of sun.

Why did they site the polytunnel where they have wizzyfax?  Is it the only option or do they have a sunnier spot available? Might be worth moving it if they can or can they prune back whatever is shading the tunnel

Unfortunately, it's the only place it could be situated.

I told them not to bother, but they wouldnt listen.

I'm just worried everything will ge too leggy, but hey ho, it's not my problem I guess.
