AK47 attempt at making feminised seeds

Freshly rooted clone throwing straight to flower and spraying daily with 30ppm colloidal silver to make feminized pollen. Minimal light Nd very experimental Have covered with a dome to keep any chance of pollen spreading when she flowers, decided minimal light is too detrimental so hoping the cover keeps my other girls safe from pollination , I'll remove from area entirely when spraying or removing dome at all. 6/8 This unfortunately didn't work. The dome on top was to blame i think. It died. Will be trying again in a 2x2 in
