        1. I’ve seen a few places offering feminized Harlequin seeds, are these going to be essentially re-breeding from the other 4 strains, and any hints on how to obtain clones?

        3. Just got harlequin seeds from you folks.
          If it is a clone only strain, what is the true nature of the seeds I purchased ?

        4. Ang, Yes. Harlequin is a clone only strain. The originator of the strain passed away in 2014 and his buddy is cloning the Mother for all.

        5. Is it true that Harlequin is a clone-only strain, meaning that in order to cultivate it, and you’d need to obtain clippings from a mature plant? I’ve purchased seeds from a distributor, and now I’m wondering…

        6. By the way, thank you for the Widow pack, our Black widow is growing like a champ. If you were to expand your collection I would love not just HarleyQuinn but Sour Tsunami as well. I fell in love with Harley-tsu and it works wonders for insomnia and body pain.

        7. Steve,

          Yes and yes…The 8-9 weeks is an approximate timeline. Not meant to be to the day. Harvest by trichomes. Hope this helps. 🙂

        8. Hi
          When you say 8-9 weeks to flower with indoor growing do you mean from the first signs of white hairs or from when you switch to 12/12 lighting?

        9. I have a 15 plant med grow in WA. One of my girls is a Harley-cross. She (along with the others) is a heavy feeder 8 weeks into veg. We have another 12 weeks before before the natural light flip. With about 20 weeks of veg, i should have a pretty good framework for flowers. Most of my outdoor ladies in the past have provided 1.5-2.5 pounds of dry meds a piece. I’ll try to get you an update at the end of the season.

        10. I am.growing a strain of Harliquin i crossed with TUT, it buds look more like Harley, its aroma is sweet pungent, almost enchanting. I use a special.formula throughout the grow, my own mix. I surpised.at how how lovely it smells, i thought i was to close to it, so invited about 5 people to take a smell, the grow smell reviews are great.

          I dropped about 2 seeds and 2 grow in the pot from last year harvest. I find that my cross, I am calling HGQuin, loves outdoor, natural light, grows 2 to 5 times in size if grown outdoor in a super large pot with.room for it roots. The roots tend to require more room than other strain I have grown. Germination was intetesting the seed membrane grows around the first set of leaves until.all four leaves pop at once. The seed membrane draws back to one leaf falling off after a week.

        11. I would LOVE it if you started carrying Harlequin seeds! I’m a medical patient who recently discovered the strain at my local dispensary … and I would LOVE to add it to my own garden. I have PTSD, suffer from a ruptured disc in my back, and have constant migraines … plus, I’ve been unable to take more than 85% of the prescription drugs they’ve tried to give me, thanks to horrible side effect ….. and I’ve gotten more/better results from a Harlequin “1:1” strain (with roughly equal THC and CBD, both in the 10% range) than I’ve gotten from any strain EVER!!!! PLEASE!! I WANT SEEDS!!! 🙂

        12. We might J. Robert’s currently working on expanding our collection, we’ll just have to wait and see 🙂

        14. Been growing H. for about a year. Indoor and out. Indoor is better. Use the outdoor for coconut oil. 5 different H’s going now for cloning. Can send pictures. Thanks for your post.
