Adding ferts in the dark
As I was adding my daily regimen of ferts this morning at 6:30am I began to wonder if there are any opinions/facts out there regarding adding ferts a good 6 hours before the lights go on?
I add my daily KNO3, KH2PO4 and Flourish (Iron and Complete) at 6:30am but my lights don't come on until 12:00pm. Additionally my aquarium is in the wall so it doesn't get much light until the fixtures turn on. So if my plants aren't photosynthesizing until 6 hours after the ferts are added am I losing some of the effectiveness of the ferts? In particular I'm wondering about the iron and other micros. The macros I figure are fine.
I'm new to dosing iron so I know very little about how long it stays available to plants once in the aquarium.
BTW, enjoyed the article/interview with Tom.
