Melons?

Right-O,managed to snag myselt a 8x15 citadel tunnel at a bargain price last year(its not up yet...waiting for the weather).In my haste i bought 4 different melon vars.. 3 from bakers creek,1 from ..er someplace else.Anyways the plan is to use 1 side of the tunnel fer toms,peppers,chillis..the other side for cuc`s and melons.Realistically, this year i`ll be lucky if i can get 1 side of the tunnel dug over and a bed in place for the toms,etc...so will the melons be ok in grow bags, if so how many per bag...was thinking 1-2 per 50L GROW BAG,would also appreciate any advice/tips growing melons in the cold,EFFING WET north west, thanks in advance and your advice good or bad is always appreciated...URBZ

I was doing work on the beds in my PT last year which meant that only one side was dug.  I put my cucs, melons etc in that side and I sat my Toms on the other side in open bottomed buckets which I filled from grow bags, The roots grew down out of the buckets into the soil underneath I got a great harvest from the toms done this way.
