I have started growing some Big whoopers http://www.parkseed.com from
seed. I got their biodome and everything is going pretty good. The
plants are getting about 2" tall the problem is that they are falling
over, they seem really weak in the structure sense but other than that
they seem to look green and have two big leave. I think I am suppose
to repot them at 4 leaves but I could be wrong.

Thanks
Seth
