How long do I have to cull the males down to be sure only the one I choose will be the daddy?
FG007 - things are looking good my man, keep it up.
From my experience and what I have seen, males grow quicker so do not be too worried to see the two biggest were males.. Watch carefully and when you start seeing the pollen sacs form I would cull one. I also would recommend trimming the one you want to be daddy down so you only have a small section that has pollen created.. One missed sac that opens prematurely is enough to cover all the plants you have out there..
Just pulling seeds out of my own first cross - 2fast 2 vast x mixed dragon pack.
