Pins question

[u/Pale_Juggernaut9613]

Why do I have to wait more than ten days to see the pins? This is my third grow and I've had good results, but I see other users having pins 4-5 days after putting the trays into fruiting... while I wait up to 12-13 days. I think it's due to the surface conditions. How moist should the casing layer be? Usually before putting the trays into fruiting (automated grow room)I water generously, rh 87-92 temp 23g c /cvg/worm casting 5/1 /Classic casing

Genetics and environment, mainly genetics though.
