You are from the USA? If it's the case there is some labs who could make an analysis of your plants, I have no idea of the cost for the cannabinoid content but it's certainly your best option to know what you're looking for. I have not seen any grower posting lab result of this cross on this forum.
How fiable are the home test for CBD content, just rerun more tests to confirm the first result.
Today is a good day. One of the Dread Bread I have been vegging for months in random places, turned out to be male. I took a few clones when I saw the preflowers, but then I got a suspicious a few days ago. Today I confirmed balls. I chopped off everything, but the main stalk. I also defoliated most of the plant. I will use the pollen to hit every single female I have, since my tent has a blue dream close to chop and will soon be free for a breeding run. This plant is strong, easy to grow, vigorous, looked very afghan early on with huge fan leaves the size of my hand. I defoliated them because they stunk like fuel and not discreet. I also have a female Dread Bread going and will update. At the moment, she's tiny and looks like a different pheno.
