Tomatoes and salads in a blowaway

My son has just moved house and has a spot against a wall facing west, wide enough for 2 or three growbags , where he wants to have a go at growing tomatoes. With 2 small children he doesn't want a greenhouse and fancies a couple of blowaways side by side, one for tomatoes, one for salad leaves. Can anyone recommend one which isn't too flimsy?and tall enough? Thanks!

 

Rather than blow away get a small lean to greenhouse with toughened safety glass.

Blow aways certainly live up to their name

From personal experience, the tomatoes didn't grow a well as the ones (same varieties) planted outside. The leaves yellowed up and the toms were somewhat bland. Then the blow away blew away in the Autumn. Thankfully

Also, the toms needed far more watering and despite the door being left open during the day, it seemed the beneficial insects were wary of entering.
