Well, as stated, I was going to take images at harvest time. Well, it's harvest time, but the lettuce is a long way off from being ready.
Lack of nutrients in the water? No. Lettuce needs less than 40ppm, and the water regularly tested at 80ppm. So, not sure what it is.
Out of all the seeds we germinated at the beginning of this venture, only the basil has been coming along. Looking pretty good too, if I may add.
We had three broccoli plants that germinated. All but one, however, have died. (The one circled in red, in the image below. The rest of the small plants on the first raft are basil.)
Except the first raft, and the last two rafts, all others contain the lettuce Chan was given. I still wonder about that. Maybe I need to try to start my own lettuce.
But, as stated, the basil is coming along nicely. If they end up growing well, we may see if anyone wants a few. Definitely way more than we will need, for sure.
AFTERTHOUGHT: Until recently, we only had 10 fish in the tank. So, maybe, now that we have a full stock of fish to produce more nutrients, well - maybe that will help the plants grow better? I don't know. The fish side of this, I had a basic grasp of, due to having raised fish when I was a teen. The plant side, however, well, I never had a green thumb like my dear ol' departed pappy did.
