Shelving recommendations for indoor grower

[sheiman]

Apologies if this isn't the right section for this question. I currently grow my orchids indoors (in Brooklyn) on a wooden Ikea Ivar shelf that is basically garbage at this point, so I'd like to get some new shelving.

Any recommendations for affordable shelves that work well for growing orchids? What sort of material is good - metal, plastic, wood, etc? I don't need lights (yet...I just moved to a new apartment, so we'll see).

Thanks in advance for any help!
