Can I grow more than one plant at a time?

I am starting up a small crop and when I began (I am a newb) I purchased those pre-transplanting plugs and planted 2-3 seeds per plug. But now right before transplanting I have 2-3 plants per plug! Should I remove each one until each plug has only one plant or can I just let them all grow so close, but be sure to cut the males before they pollinate?

You should only put one plant/seed per pot/plug.

mogie, don't you think that bagseed should be the exception? I mean, I've got so many of them that I'd plant 6 per peat pot and then kill the weaker ones 4 days after sprouting.

Even if I had a lot of them I wouldn't kill the weaker ones. Each is a potential plant in its own right. Given what it needs it will become a beautiful girl. Why waste anything?

So theoretically could I let all them grow (those with more than one seed) until I can tell the sex then cut the males? Too better my chances?

no, not at all. you need to execute a few so you've got one per peat pot. or you could risk all of their health and cut them apart, separate roots, and transplant them(not what I recomend).

me and mogie just differ a bit on how to start seeds like this.

Ah Ok, thanks.
