Kaliseeds states his KAli-Humulus wich you linked have up to 17 percent Thc, and the effect can be described as benefitial and soothing when smoked.
As i understand it ,this and the other Plants he sells seem not to be Hops outcrosses (opposed to what some believe , but his Descriptions are bit confusing, and still not shure if actually did it)
But what is confusing : further down on his Kaly-Humulus decription he ads a History, wich tells he managed to outcross Canna to Hops in 1998…
