Shelf on back of greenhouse (outside)

I've done a search but it came up with nothing.

I'm sure I saw someone on here post up pictures of a shelf they made on the back of their greenhouse.

Can someone please point me in the right direction?

Space is a premium and I could do with such a shelf for my ferns.

TIA

 

That's what I did on the inside and was thinking of the same for the outside.
I'll get my thinking cap on.

 

Just been outside and sadly my greenhouse has the bolt strips only on the inside.

 

Hi,

What I have used on the inside is a few of those standard brackets that bolt to the frame slots and then used some upvc window board, its looks neat, clean and of course rot proof.

For the outside with no slots in the frame you could use this type of fitting but just drill some small holes through both parts and use some metal self tapping screws.

Find using some small 50mm L shaped backets fitted to the uprights so they just rest on top of the rim of the pot , preventing the pot from moving or falling over , partic with a heavy trailing plant.

 

On similar lines as @ricky101 if your channel is the same as mine you could use L shape brackets (or get some 3mm aluminium strip and bend yourself to fit) and drill through the glazing frame, bolt to the frame then a hole in the front of the bracket and you could use standard greenhouse brackets.
