Evening all, hope everyone's well  I kindly had some mini white cuke seeds given me, one is now around 2 ins tall and outgrowing the mini w/sill GH, i've heard they can suffer with stem rot, so my question is, how deep should i pot it on or  should i even be doing that yet? Thanks in advance

Hi there!  I am growing the same cuke's.  Its my first go at cucumber growing but this is what I have done so far...I planted 3 seeds in a mini greenhouse 7"pot, thinking that as cukes are temperamental they wouldn't all germinate.  In typical fashion, all three of them sprouted and after taking advice from this site I repotted them separately into 4" pots.  They are all going great guns now.  One is about 10 inches high, the other two are a bit smaller at about 7 inches. 
I repotted the largest one yesterday into a 12" pot, where it can stay for good now.  I planted it on a 'mound' within the pot.  I shall do the same with the other two asap (I ran out of compost yesterday!).  They are still on the window sill at the moment but I am thinking that I will start to put them outside from tomorrow during the day.  I believe that miniature whites grow equally well both in and outdoors so I may try one in the mini greenhouse and two outside in a sheltered spot.  I am too much of a coward to take them to the lottie though - they will be staying at home with me!

Thanks, will pot it on and get it out into the coldframe!! How deep did you pot them on, is it the same as most things, up to the two first true leaves?

maxibo's advice was

I planted it on a 'mound' within the pot.

This is good advice and stops the stem rotting 

planting them deeper exposes the stem to moisture in the compost

Coming to my aid again mos, thank you  "note to self", read replies thoroughly!!

Hee hee!  Sorry I didn't get back to you sooner - I had to go to work. Yes,  I just VERY GENTLY placed the entire pot of compost and cuke (minus pot of course) onto fresh compost in larger pot and then sort of tumpted (is that a word?!) a bit more compost around to fill in any gaps and make it firm. 
I did this on sunday, put them back on kitchen window sill to get over the shock and then took a deep breath and put them in my small plastic greenhouse this morning.  Gawd knows what the neighbours thought if they heard me as I said 'now look, don't go dying on me - you only have to stay in there til tonight'.  I shall bring them back to kitchen window sill tonight.  It's a bit chilly here now but I'm going to be brave and leave them out til teatime. 
I must point out I HAVE NEVER GROWN CUCUMBERS BEFORE! So you may want to take more expert advice.  I've just done what I think best.  Oh, and I sang and talked nicely to them when I was moving them about - that may or may not help!
