It's hard to tell from your photo, but in this situation I would show a client black "wood" blinds ("wood" because real wood in a bathroom can warp from the moisture.) A 2" slat would be great - particularly if you have the room to inside mount them. :)

georgi02 "follow some simple guidelines, the ones that people frequently aren't told when buying wall gardens and you end up finding out the hard way" Plant walls are fashionable and seem ideal for small spaces but it would be good if the stores that sell the bits and pieces told people it's not just a trendy decor item, it needs some gardening expertise. mutcherson, is there any space between that deck and the fence? IMO the most successful low-maintenance gardening is the right choice of plant growing in the ground. As soon as you start messing around with unusual plants, unusual containers, unusual locations, you start having additional challenges. But I reckon if you want it's worth having another try with a wall using georgi02 's instructions. Succulents are easy to grow from cuttings and forgiving of lack of water. When you take cuttings of succulents you are supposed to put them aside for a while before potting them and I have found pieces I forgot I cut weeks earlier and managed to grow them. I have had some problems with succulents but that was because of frost so you you won't have that challenge.

I agree with Country House Girl, go with panel glides if you need them. I am currently shopping around online for mine to cover a similar door opening but only 6m wide. I hope to get a light filtering style to keep it soft - as opposed to block out. And will be tinting the windows for just that bit extra privacy and also sun fading protection. However if I didn't have neighbours I would just leave them bare

Hate vertical blinds too! So much so put curtains on my sliding doors. On my casement windows have holland or cellular blinds as easy to pull up to open window I suggest block out blinds which can perhaps be made big enough to cover all or at least half windows so gives you flexibility re light control if separate controls without having too many separate blinds
