I've worked out a method of turning a female into a male without any treatment such as colloidal silver etc. I've tested this on 3 strains (Critical Kush, an indica I've grown for ages, and a random local sativa) with 100% success. I simply place the chosen plant in an airtight container (such as a large garbage bin) in dark hours. I start doing this three days before I switch back to 12/12, and continue into the flower cycle until a good amount of male sacks have shown. It is even more effective if I spray the branches coming from the very lowest nodes with a heavy dose of colloidal silver (50ppm) three times during light hours. The bottom branches will more than likely suffer or die but all growth above will shoot balls like crazy.
But note, colloidal silver is not neccesary unless you want to collect a good amount of pollen to create R1 seed. I've been selfing my girls, so im after male and female traits on the same plant to create S1 seed, so I've discontinued colloidal silver use altogether.
I hope this helps other growers to get the desired results with very little effort, and little to no use of any toxins.
I wonder if the seed banks use this technique...
