treedawg got my mind working on how to do what we do using only one hand, and how we can make some addition to the OG FAQ for growing with special needs.
here are some links i found today:
http://www.carryongardening.org.uk/gardening-when-you-use-one-hand.aspx
http://www.amputee-coalition.org/resources/adaptive-gardening/
https://www.accesstr.com/Lend-A-Hand-Universal-Assist-Devise-p/lah66.htm
there are more links within them each, too.
