You can look up the Jim Beam test, I think it’s called. It won’t give you numbers but it can give you an indication of a lot of CBD or a little.
Those are cool looking plants. They look strong. All CBD stuff I’ve grown have done very well outside. Probably easier to grow than an hybrid thc strain.
I have a strain from a friend in Switzerland thats called CBD Kush and it uses Ringo’s Swiss Gold. I forget the other parent. I’m going to grow that again soon. Best vibes on the summer growing! peace
