How do you breed two auto's to make a hybrid or seed stock?
Same way you breed regular strains.
Grow all the autoflowers you have and choose the very best female and best male.
Your offspring will be more stable then the parents if its the same auto strain being crossed to make seed stock.
The variations between offspring will only get less over time and stablize out into a solid strain every time you grow it.
To create a auto hybrid just take a auto,
for example Lowryder Diesel and cross it with a different auto..
Lets say..Easy Ryder(lowryderx Ak-47)
now choose a male from one and a female from the other..
store male pollen after breeding the first time..
now grow offpring and choose your fav female hybrid, one thats high in tric production, smell, yield etc, and backcross it with the stored male fathers pollen..
repeat the proccess 4-6 times and you now have a very stable or close to stable autoflower hybrid.
just keep that original fathers pollen and your backcrosses become a snap
