I believe it works out to 12%o 15%, which for some is too low, but the high is so blissful, relaxing, and creative that I don't care. Quality comes before quantity in my books. Plus it's great breeding stock. My only negative observation is it had tiny orange brown spots on its leaves when all the other plants were fine. Not sure what deficiency that was about for the Sinai. I tried to figure it out but all the pictures of mineral deficiencies weren't exactly what I saw. It did flower very early though so that was a real positive attribute.Ok I'm a lightweight anymore but not so much back in the day and I liked Moroccan hash back then. Like I said it's not to strong and it's a straight up old school landrace .I was under the impression that Sinai is not all that potent as well and similar to Morrocan, a semi-auto landrace, how is it ?
