Yeah, I like a new blade, alcohol wiped every time. Not every cut, but every time I take cuttings. I also have scissors that are dedicated to indoor and if any cross contamination happens....well then I have a new pair for outside tomatoes, peppers and such. Because shit happens. lol I'm waiting for a battle of some sorts since I just brought in my citrus plants for the season. They aren't in my grow area, but in the house. I've had my mom send me non cannabis plants from reputable places and had big issues with taking them in. Learned a lot from that. Thanks mom lol those citrus plants where a mother! Never had scales before that. Those fuckers suck...no pun intended.
