I have a newer smaller system that I have kept for cycling (to have the nitrification bacteria population established). It looks like the system is doing well now.
I have bottle gourd (churakka), long beans (payar) and amara payar (not sure of the English name – hyacinth beans / gour beans?) planted in it – just one plant each. Bottle gourd plant has a couple of small bottle gourds on it already. Will post how well it does.
