yes technically this should work to make seed. this is how some used to make seed, they would stress the chosen plant, and because of that stress the plant would
flip and change into a male, and produce pollen that was female.
so yes this would work but you have a higher chance of the plants turning hermie, so instread of stressing the plants, instead just spray a whole clone with either silver thisolate, or Col. silver.
you can make these yourself, or you can buy the spray already made. the spray does work, as i have succeeded several times in getting seed, i have been using the silver thisolate for my spray.
its easy to use, spray once 5 days before flipping, the first spray is done and the plant is put into darkness and the returned to the veg cycle, in 5 days you spray again and
put it in to flower, in five days spray again and repeat until you see sacks appear, these are reversed and will make female pollen and later female seed.
so if you ever want to do it i have the recipe for the silver thisolate and it will last you forever. or you can make your own Col. silver spray, real easy to make,
if you were to buy the spray its like 25.00 dollars, if you were to make the silver thisolate it would cost you around 10-12 dollars. if you were to make the Col. silver it would cost you about $10
so either spray does work, easy to use, or you can buy it, it will be a good investment as you can make your own seed and wont have to buy any, that is one reason i started making my own seeds, they are pricey as you know. making auto seeds is a bit harder , hope that helped you
