Outdoor shelving v. Shadehouse..Maria's conundrum.

[peeweelovesbooks]

So,

As you can see from the pictures I posted in the Florida growing group, I have no more room for plants.

So, I have reached the critical point where all of you at sometime or another have found yourselves: WTH do I do? DO I stop buying orchids???( INSERT Halloween horror music) NAY!!!

I need more room. I can either save up (HAHAHAHAHAHAHA) for a shadehouse or, buy more shelving.

So, I have been looking around and found these shelves:

STRUCTURAL PLASTICS Dura-Shelf All-Plastic Shelving with Adjustable Shelves

The reason I like these is that
1) they are adjustable
2) they are plastic hence avoiding the problems of rust, fungus,
3) they have vented shelves
4) the cost isn't outrageous
5) they can fit on the slab and I can dismantle them and take them with me should I move.

Why am I hesitating? Well, I'm not sure that the plants are going to be sufficiently protected. So, I thought that I could wrap shadecloth around the back and sides of the shelf. I'm not sure it would work though. So, this is the reason I'm coming for your expert opinion.

Do you all think that idea would work? The structural plastics line also has tiered shelving (which I'm also planning to buy) that is not protected for such sun loving plants such as schomburgkias, that require full sun.

So, I'd love to hear your opinion and advice before I purchase anything.

Thanks peeps!!!
