Hello,
for a few months I have been interested in aquaponics. I started an impromptu system with my aquarium, but my goal is to begin commercial cultivation. I read a lot of things from the forum, I watched a lot of videos, but I still have questions. I am currently calculating the size of the system I will need, the necessary funds and how long I can get back the investment. One of the main questions at the moment is: How long do lettuce grow (for example) under optimum conditions? How difficult is it to achieve these optimal conditions?
