I took 25 seeds and sprouted them all seeds off the same mom. put 10 seeds in 24/0 light sced and 10 under 18/6 light sced, all same nutrients conditions lights,etc only difference is light sced..after vegging them for 3 weeks, i put them all into 12/12..the 10 that had 24/0 light sced got 5 males and 4 females and 1 herm..the plants that had the 18/6 light sced i ended up w/ 7 females and 3 males..is that proof that light sced and the right conditions provide a better female to male ratio? or is it just plain luck of the draw seeds? ive done this test 2 times now, both times i had more females out the 18/ 6 light sced..last run i got 6 females and 4 males under 24/0 and 8 females and 2 males under 18/6..All in 4x4 rock wool flood n drain table w maxi grow by gen hydroponics, and 200 watt cfl light w 6400k, room temp 72 degrees w a ph of 5.6-6.0. then flowered under a 400 watt hps w maxi bloom same ph, same room temps, etc...Now, does this prove seeds determine their sex by enviroment or has it just been plain luck that 2 times i ended up w/ more females under 18/6????any body have anything to add or has anybody else done his test??
