OMG Mr. Sin, those are frosty!!

What strain is it and how long have they been in flower?

Do you have a magnifying glass? A hobby store or Radio Shack, has them. You will need one to determine what stage your trichomes are, for your harvest. With nugs like those, you won't want to leave it at a friends. But, that is better than the visitor on his way.

I don't know if there is something that will 'speed' them up. Must be a few tricks, the expert "Master Growers" know? pr
