Thanks to the both of you for the suggestions/information! Will follow up on them as soon as I can.

I agree, oldmac. Stealthily growing a few plants is likely the way to go. Seeds can often be found in the bags, no? Have dabbled in the past with hydroponic greens in the winter. Sounds like a project.

Kudos on your philanthropic work. I can think of no better cause to devote your time to.

Thanks again!
