Allotments 4 All

OK, I've got a greenhouse + a friend who's out the country all summer + has said I can use her's too.

To plant in them I'm growing toms, chillis, sweet pepper, cuecumbers, aubergines + watermelons.

If I keep one humid + the other slightly drier (watermelons don't like as much humidity as other melons) will it be OK to put the cues in with the watermelons?

Or is there a better combination?

We grow toms, peppers, cus, melons, aubs, chillies in the same 'house.

From memory, cus like it humid and toms like it dry - I don't know about the others.
