I used cheap potting soil and added some perlite to it. I'm not sure, but I don't think there is going to be a flower
that we are going to get to see...I can see inside the bud which is opening and all I see is a very small round thing...a wonder egg forming???? Maybe the flower
is so small that it opened inside the green part of the bud and now it is making it fruit/seed
pod (egg). I was thinking that even though I have not fertilized mine and they are under lights for 10-12 hours daily, that some of you that have smaller plants
might need to fertilize yours or use something like miracle grow soil...also it seems that once the roots start growing
they take off fast, so if in doubt go ahead and transplant, to be on the safe side.
