Our New Line of Clones from Tissue Culture

Lablets – we can no longer contain them!

Lablets Grown in DHN's Test Garden
These Fire OG Lablets grown in DHN’s test garden show shorter internodal distance and greater branching.

After over a year of research and development, a state-of-the-art laboratory build-out and dedicated work by our team of scientists, Dark Heart Nursery is proud to introduce Lablets. This new line of clones is propagated using tissue culture technology. The release of Lablets means you’ll be seeing more Dark Heart clones at a dispensary near you – just in time for spring! 

Lablets are produced using a new type of stock plants which are created in our tissue culture laboratory. These new stock plants, which we call “producers,” grow much differently than traditionally produced clones. By taking cuttings from producers, we are able to create clones that develop similarly to those growers are used to, but with added vigor. What we are hearing from our beta-test partners, and seeing in our in-house trials, is that the clones have the health and vigor more characteristic of very juvenile plants; such as seedlings. From our in-house Fire OG trial, we’re seeing that Lablets produce more branching with tighter internodal distances. Ironically, we’ve received some anecdotal feedback that the opposite may be true in some Indica varietals, where growers are actually seeing longer branches.

It will be a while before we unlock all the secrets Lablets have to share, but we’re eager to blaze this new trail with you! As you pick up Lablets, we hope you’ll share your photos and comments with us by posting below, reaching out on social media @DHNClones, or through the contact form.

Rest assured, we are not resting on our laurels! Internally, we will be continuing to develop the Lablet line and our tissue culture processes. We will be experimenting with production techniques, and product configurations. We will be running a variety of experiments on “producers” themselves. In the lab, we will be honing our lab techniques, ramping up production, and developing a virii eradication protocol. It’s a great time and place to grow cannabis; we can’t wait to share with you what we find out!

Lablets will be taking their place next to our classic premium and Heartlet clones on a dispensary shelf near you.  Be sure to sign up for the drop alerts of Lablets, Premiums and Heartlets on our website.

Look out for this label on your DHN clone trays at the dispensaries.

What are growers saying about Lablets?

Current growers testing Fire OG & Dream Queen Lablets side-by-side our Premium clones using the same exact growing processes share the following results:Lablets Test Tray

“[Lablets] didn’t miss a beat” (Week 1)

“The [Lablets] have rooted fast about the same rate as the cloned version but a bit more rigorous.” (week 1)

“I’m excited to see the uniform and healthy growth from all the [Lablet] cuts.” (week 2)

“General Plant Health- Excellent!” (Week 4)

“Branching-Tall with nice new growth and vigorous” (Week 4)

“with rapid new growth both sets have roots coming out of the 2 gal pots and healthy and white” (Week 4)

    1. Same as any other clone, they just use a media containing a cocktail of growth hormones for the cuttings to root in vs. dipping and sticking them in rooting hormone. Love the ungloved picture above showing their unprofessionalism…

      1. Actually, tissue culture protocol almost always calls for ungloved hands as it requires high dexterity and the hands are continuously sanitized anyway.

        And the process is quite different than just rooting in hormone. The plants must be completely sterilized of all endogenous contaminants. During culture, they’re actually not typically rooted. Instead the tissue grows without any roots, requiring a complex blend of sugars, minerals, hormones, and gelling agents. After several weeks the process causes the rejuvenation of the tissue. This results in the increased vigor and branching we typically see from TC.

        1. I’m starting my cultures soon, do you have any videos about your process on how large your node cuttings are when you culture, or your reculture process when you go to harden off to rockwool. Also are you going straight into a rooting media or a standard multiplication media. hope to see a response. I have ga7 Vessels but vented because the protocol I’m following warn about needing venting.

          1. Nah but I am very interested as I am into genetics and this would be a very logical way to keep samples

  1. I got some GG4 babies from RCP, I think they might have been sitting for a few days. The roots were a little brown. %50 look ok but still slightly unhealthy roots. %30 didn’t root and turned yellow( looks like a mg or sulfur deficiency) %20 rooted nice but then started showing the same signs. After intensive treatment in a very good environment they wouldn’t come back. Would you suggest scrapping them all or keep the %50 that look kinda ok. Advice? I’m thinking it might be a root disease.
