Yes mate once they're up, keep them in the bay window as much light as possible, bring them back about a foot from the grass at night. To get them to germinate I put them on a tray on top of the radiator first ones took about five days.
Forgot to say once frosts have gone ill use just six of them in the green house. brother in law and mates have the rest, they have all put there orders in Lol.
