General update
Woke up this morning to find the black-eyed peas grown at least 10cm in length since last night, and it's now almost touching the grow lights.. I don't know what's going on, but fish waste is like steroids to those plants :)
I finally found rosemary yesterday.. I was hoping for seeds, but I found a plant and will probably transplant it in a couple of days, as I have some business trips to take care of. Please note that this a prototype aquaponics system, so we'll conduct experiments until we build a production one.
