@kfigerm OK that is helpful, right now I am using my experimental reuse of the pyramid, she is 8 days old today so the roots won't be coming out the bottom for another week. As it is at the moment the plug is sitting on the wire rack with is about an inch below the rim of the bowl which is about 4in deep. The clay balls are just keeping the light out. The thinking here was that the roots will grow down but I don't think this is good, I was getting preoccupied with being able to lift the rack out but I am now leaning towards your already tested method.
So then how does this sound... I fill the bowl with clay balls about 3 inches deep, then there is a half inch gap to the bottom of the rack. I don't fully understand the bit where you say... A rule of thumb is the runoff should be soaked within 1-2h after watering.
Or I could get rid of the rack and just have the plug sitting on the balls, (racks balls plugs, sounds like a sex shop). If I went this way how deep do you think the plug should be buried.
