For aphids, I prefer cedar oil. Earth Juice makes a product called GoNatz that works very well that contains cedar oil. Also, lining your growbox with a couple strips of cedar wood helps quite a bit with pest control as well. The other great way to get rid of your aphids naturally is like PGS420 said, get some ladybugs, could be difficult this time of year though.

JeffersonStateGrower Reviewed by JeffersonStateGrower on . Need help with Aphids I am on week 4 of veg and I just got a mad rush of aphids that I cant kill. Im still very new to growing and I have only been sparying "Safe" bug spary every two days, with no luck killing them. I have been pulling all my plants out every two days to clean the room top to bottom. My room is a 8 foot by 6 foot room with 2 1000w lights. Fresh air intake with air filter, a 6" exhust fan going to the outside and one door to the room. What else can I try doing? Rating: 5
