Great answer Zandor!
I noticed the FAQ has been expanded. Nice work. I had a quick look and didn't see anything about hermaphrodites. I think it would be worth adding this information. I have a picture of a hermie if you think it would be worth adding also. You forgot to mention that rockwool isn't the best for propagation of cuttings.
