… for the bacteria and for the fish to arrive.
I’ve also ordered a new 250 liter grow bed so that we are closer to a 1:1 ratio between water and grow beds. This addition was mostly because I was unsure if we had enough filtering material to clean up the water. It’s true that at the beginning, I shouldn’t worry about that but since adding a new grow bed when you’re seeing trouble doesn’t seem like a good approach. And this way, we have more gravel space to plant more things, closer to areas with more sunlight.
At the moment, our grow beds are in a semi-shaded area, with not much direct sunlight and between that and the fact that we don’t yet have fish in the system, the growth rate we are seeing is pretty poor.
Over the next few days, I will post a few more pictures to my Flickr group on the current state of the system and the strange marks that appeared on the leaves of our lettuces. Maybe someone will be able to help us diagnose what’s happening and give us hints on how to solve it.
