Kiwi plants

I recently bought 2 kiwi plants hoping to train them along wires at the back of the plot - I thought the back of the greenhouse would provide a sunny sheltered location but now the new shed is up, I'm worried that area is too shady...

I've potted them in big containers and will keep them by the compost heap until the autumn, while I decide what to do with them. 

One is an Issai kiwi (grape size fruit) and the other a sweet red kiwi. It's exciting! Hope I'll manage to find the perfect spot for them...
