A pair of Robins has graced us with a nest. They chose the top of the electrical panel box, likely because it constantly throws off a bit of low heat, good choice really. So far, she has been extremely tolerant of our activity in the area as this is right next to the back door.
I managed to get up there when momma was off getting dinner and snap a picture of the inside of the nest.
The aquaponics system is humming along. The original plants have doubled in size in Grow Bed3 (GB3)

The spinach and kale are lagging behind in GB2. Of the 20 or so seeds of each we planted, only a handful have sprouted.
The lettuce mix seeds we broadcast have been sprouting like crazy.

- Temp: 71F
- pH: 7.2
- Ammonia: 0.5 ppm (24 hrs after addition of ammonia)
- Nitrite: 3.5 ppm
- Nitrate: 80 ppm
I've been adding 40-60 ml of ammonia (to get to ~4ppm) every day (the fish will do this when we get them) and the bacteria are starting to change it from ammonia to nitrites and nitrates. The ammonia is going down to zero every day, but the nitrites are still at 3.5 ppm. I interpret this to mean that the Nitrosomonas bacteria are doing a great job converting ammonia to nitrite, but the Nitrospira bacteria are lagging a bit behind converting the nitrite to nitrate.
When ammonia and nitrites (both of which are toxic to fish) are at or near zero we can stop artificially adding ammonia and begin adding live fish which will produce their own ammonia and the bacteria cycle should just keep cooking along. I expect this to occur in the next week or so.
Since the kale and spinach seeds germinated so poorly, I moved them to the edge of the GB and planted several more plants from Home Depot in GB2 and a couple of zucchini in GB1. I am hoping to harvest the lettuce mix before the zucchini squash take over the whole space.
All the seedlings, either sprouted in a GB or starters transplanted from Home Depot have been amazingly tolerant of getting moved around in the media. Just to get the ones from Home Depot into the system, they had to undergo a rather traumatic "de-soiling", in which the roots were vigorously shaken and then rinsed several times in water to remove the potting soil.
Just for curiosity, I have separated all the leeks, which were in one large bunch like grass, into individual stalks over a few days time all except for 1 or 2 have lived and seem to be thriving. I also moved several of the tiny lettuce sprouts and all have survived (so far).
