Just a suggestion for anyone new to the clone game, whether trading or buying.... Do yourself a favor and buy a usb scope. I paid like $30 for mine off Amazon and it's saved my ass multiple times, and just did so again. Fist thing I do when new genetics come in is scope them. I learned my lesson the hard way.
Russets are a simple fix if you ID them right away. Without a scope, they can easily get past a month long quarantine without showing any symptoms. Once they're in your garden, dealing with them becomes much more difficult. By the time your plant starts showing the characteristic curled/twisted leaves, you are already completely infested. At that point, they can be a nightmare.
So, like I said.... Do yourself a HUGE favor and get a scope. The nasties are out there. Be safe folks!
