I've just planted them all horizontally, the more pics I looked at and more info I read the more sure I am. I've just got into bed now 11pm here. Ill try and get a picture tomorrow. It looks very different now it's planted differently I may have to give it a week or so to sort it's self out. I'm not sure how well it will grow without extra C02 but I'm going to keep my fingers crossed. Thanks for your help, I'll let you know how it goes.
