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?
