Hi
I bought some teeny tiny melon plants that were suitable for a coldframe a month or so ago, put them in a large tub in a plastic growbag frame . . .and now they are huge.  

  In the last week or so they seem to have grown another foot, there are tendrils everywhere, its ginormous.  

However, I can see a few flowers but no fruit. So - how big do these get, do I need to pollinate it and if so - what am I looking for? Should I pinch it off to stop it growing.  . . 
Blimey, basically what do I do with this monster to get some fruit. I was not expecting it to be so big - very sceptical of getting melons in this country 

Anyone grown one before - or got one going? Help please
