First time grow, advice please

[PhatJay]

Should I trim off the fan leaves for that last week or leave them on?

I don't think there is a definitive answer for that question, the cannabis growing community seems to be split into two on this subject. I know that probably is not the answer you wanted, but If I gave you my opinion, the next post will be someone who thinks the opposite and is just as likely to be right.

After cutting how long do they need to be in dark to dry?

It willl depend on temperature and humidity, it generally takes 3-10 days. My 1st crop took around 10 days (winter) my second crop took around 4 days (summer).

And how long until fully cure?

I'm still experimenting with this, so far my weed has got better with age.
