I have just sown some Bok Choy seedlings into an old unused wash basin, I cut a piece of board to fit over the top , used some small net cups and used perlite rather than Leica pellets.I am using the Kratky method with no pumps etc.
The nutrient mixture is PH neutral at 7 and the strength is 1.5 EC.
Bok Choy is one of the few chinese vegetables that really enjoy a neutral PH of 7 most other plants grow within a range of 5.8 to 6.2.

I have added another photo of Bok Choy but in my DWC I planted 3 weeks ago using the same nutrient and ph requirements.

Nice looking. Any reason for using perlite instead of leica? I tried using vermiculite and some dropped out of my netpot. Noticed that it holds water very well but a little messy to handle and cannot be recycled.

It is already 2 weeks and the seeds still not germinated yet. How long does it take to germinate?

You are correct Grace it is very messy but holds the moisture very well, the Leica balls are good for well watered plants , but I used tiny net pots and they would get hot if I used Leica and would burn the tiny seedlings.
This is about the only time I use perlite except for lettuce in the same pots and setup.

My seeds germinated in about 4 days, I find if you keep the soil or foam too wet the seeds will rot, as mentioned in an earlier forum I start my seedlings in soil to establish a strong and long root growth, which enables the seedling to be planted lower in the net pot. This was another reason I planted the Bok Choy in small net pots using perlite as the plants were tiny and small root length so I used perlite to keep the roots moist, if the roots had been longer I would have used leica balls.

My baby bak choy usually germinates in about 3 to 7 days. There are rare occassions when I thought my seeds failed to germinate and they spring a surprise on me after 1 month when I am not looking. Relax...wait.... and try again. Good luck.

I guess the seeds needs some privacy to undress! Die from shyness?

Luckily I am not guilty of homicide. The culprit is I bought an unreliable brand of seeds BEST!!
