Have you tried searching for CELSS, which stands for Controlled
Ecological Life-Support Systems?

There may not be popular accounts for most CELSS research. You may have
to rely on research literature, especially abstracts.

To find some recent abstracts, search PubMed for: CELSS plant or ISS

PubMed: http://www.ncbi.nlm.nih.gov/

There are many problems, such as finding an optimal growing medium,
optimal light level and light source, optimal air flow needed for
pollination and gas exchange, dealing with accumulation of ethylene in
a closed system, overcoming lack of oxygen diffusion in tissues under
microgravity, etc. An overiding problem is if the Earthbound research
on CELSS will even be applicable to CELSS in actual space conditions.

You might wish to email the authors of studies you find interesting and
ask for reprints.
