cucumbers

I have started growing cucumber plants from seed, how big should they be before I put them into growbags?
This is my first year growing things, as I have just got myself a greenhouse, and loving every minute of it.
Thanks

 

With the current weather, I wouldn't put them in an unheated greenhouse. When they have a couple of proper leaves (not the ones they start with) then pot them up into small pots. I put mine into growbags when they are 6 - 10 inches tall.

Good Luck
