alright. I have heard that generally if its a bag seed its nmost likely not an autoflower. could anyone elborate on why that is?
If it's bag seed, it means that you (or someone) bought that weed, and pretty much no one grows autos for selling. Auto's are mainly for people who live in climates that normal strains can't handle (Auto's come from northern Russian Ruderalis stock, and grow in temps cold enough to kill most non-autos) or who are growing in areas where affecting a 12/12 light cycle with no leaks isn't possible, since auto's will flower even under 24 hour light (Because they naturally grow in climates where the sun never goes down during parts of the year). Combine those traits with the generally reduced yield (Can't grow 10 foot monsters from most autos), and generally reduced potency (As Ruderalis has much lower levels of THC, although it is worth noting that Autos are generally higher in CBD if you're lookin for more medicinal and less stony), and you have a plant that doesn't really pay off to grow for sale. Autos are (Mostly) personal plants. Hence, most weed you buy (And thus most bagseeds) are from non-autos.
Anyone wanna give me some imput on weather they think I should try putting the larger one in a 12/12 to see if it starts to flower as a male or female
My advice would be don't. They will start showing their sex before too long, and if you put them into 12/12 and then flip back to veg you will stall your growth a bit. I would just keep an eye around the 5th to 7th nodes, they will show preflowers early (Might even already be there if you know what to look for).
