Hi GanjaRebel , always difficult to form any valid opinion as to a males worth , but this one has the look.
Flower placement and density would be good for a girl , no stem clusters to cause mould , long fan stems help airflow , deep odour and a showering of capitate trichomes , all would be positive traits if passed on.
Thanks Greyybeard , these are proveing wonderfull material to work with and have found some real keepers here.
All the MBS and female outcrosses seem to need a little more Mg than usual for their type , a dose or two of epsom salts avoids premature inter vein yellowing , calmag or similar would achieve the same result , yield is not effected and it makes for some nice late colours.
There are at least five identifiable leaf traits in the line , the single blade here seems unique to males so far , and would allow early sexing if true.
That male had been in an unheated greenhouse and had been airfrosted at least three times , in a litre pot it survived to produce pollen but shows nitrogen and magnesium defficiencies from low temps and poor light.
The girls indoors are a healthy green , and benefit from a shot of Mg.
