Hey y'all! Here's an update for Day 17 of flower. We're just got the trellising in a couple of days ago and are getting the lanky ones laid out. All in all I'm pleased with the way the aquaponic side is keeping up. At Day 10 we added the Aquaponic Elements into the fish tank to increase the trace minerals (Ca, Mg, Fe, K) that are in short supply in fish waste. So the water turns a deep red for about a week with an increase in dpta chelated iron but the fish don't mind it and it does help increase flowering density so you live with some red water for a week or two. This room is not optimized yet. The CO2 lines are in but it wasn't until just yesterday that we think we got the interlock figured out on the Sentinel controller so we can shut down the fans when the CO2 is running. Since we're averaging ~600 uMol/m-2 s-1 PPFD over the canopy if the controller is working like it should we'd like to maintain CO2 levels of 800-900 PPM. Of note the Aquaponic side showed pistils a few days before the hydro side but the hydro side has caught up and so far the flowers an the hydro side are running a tad bigger than on the aquaponic side.
