Yea it does seem like a bit but remember that the bubbles from the air stone pop and the moisture gets on the bottom of the basket, that moisture alone is enough to keep a young seedling going, Ive read about a guy who does DWC with no air stone claiming the gap between the water level and basket provides the roots with sufficient oxygen... But yea I'm ok with being wrong 😜
As long as the roots are getting a continuous supply of oxygenated nute juice, it doesn't matter if they are in the juice or being bubbled by it.
Figure you're starting in aeroponics and growing into hydroponics.
It's called the kratky method what I was referring too. There's heaps of different stuff about it on google... I don't think I would recommend it but it's worth a read.
Roughly 2 weeks... I'd be starting it on nutes for sure specially cal-mag and microbes and little bit of nitrogen. Water holds very little nutrition specially compared to soil......
Speaking as a soilless (coco) grower, if you haven't, get your nutes going. Half what you are going to wind up giving them. That is, if you wind up giving full nutes, give half one time.
Your roots might have been disinterested in plain water.
