Ive been creating my own x breeds for 8 years and i only used fluros to do it,my advice would be to give the seeded plants just as much care,light and attention as you would a plant thats about to give you some bud lol.
I have now invested in a decent hps lighting kit and i have a thread where i am using one of my own breeds that i have finally stabilized(i think)to make some new seeds using a mainly indica triploid male and female,i also have a mainly sativa male and female if you want to have a look at that i will be including pics all the way to the end.
I will only be fertilizing one branch on each female as this will give me plenty of seeds to start my new batch which i will then select the best from and begin to crossbreed these with hashberry.
I may also use the sativa male to fert the indica female and vice versa also only one branch each so theres still some good smoke for me,all depends on how big they look as i can always store the pollen for later use as i only have a small setup.
Hope this is of help or interest to you
