i also try to give it some sunshine thru the window when i can,few hrs)
direct open window for some true sunrays,when its not to cold,few hours here and there) takes vigilance on my part,but its not like its all i do
too cold now for any direct sun but window light is warm to the hand i let the get few hours of it
its gonna be on 18/6 for few weeks before i sex it
it could be a male and if so ,care less i want the pollen for cross breeding

if its female i hope to at best get a oz from it,and somecutting its it vegg stage to keep the strain alive
peace
