Killer idea as usual MC One! Area 51 has the potential to be a very potent strain from the sound of things. Maybe G-13 will bring some of it's crazy bud traits to vortex... I'm thinking super dense baseball thickness nugs of vortex.
Long story short I could not cull any additional plants because they are covered in glands even on their cotyledon leaves.
Looks like all 11 are keepers at seedling stage
It is very VERY
rare to have true stalked trichrome glands on sprouts/seedlings... especially of the cotyledon or first set. I've heard people going on about their "gooey" seedlings numerous times & have even been asked to confirm it in person twice... never confirmed. They are ALWAYS cystolith hairs.
Many plants have them. Cannabis creates cystolith hairs (particularly thick on sprouts/seeldings) for a number of reasons including:
Herbivore deterrent --- makes chewing unpleasant/rough; can cause irritation of eyes/glands/skin through abrasion and/or allergic reaction (many people report puffy eyes and itchy skin after handling cannabis, which is likely due these cystolith hairs).
Insect deterrent --- inhibits insect mobility (rough terrain); excretes anti-insect compounds to repel/sicken certain insects.
Disease protection --- Hydrophobic nature of hairs helps shed water off plant (like duck feathers) to prevent wet pockets, creates barrier between plant tissues (stem, leaf) & pathogen (spore, bacteria).
Other stuff... I'm sure.
You can see why a sprout/seedling would want a lot of those. Interesting points about cystolith hairs and their frequency in various cannabis gene pools:
--Many breeders have seemingly bred ALL cystolith hairs off their plants in bloom to make room for real THC containing trichromes. In my experience these strains have usually have very high THC, but limit resistance to insects, mildew, and rot.
--Outdoor strains tend to have a lot more cystolith hairs than indoor strains, and indeed, even when comparing the same cutting in and outdoors the outside one will have higher counts.
--Some strains which look "frosty" but don't get you very stoned (commercial strains) have very high counts of cystolith hairs. The extra hairs grow everywhere stalked THC containing trichromes do, so they make the buds look more potent than they are.
Cystolith hairs can be distinguished from trichromes under a handheld microscope (30x or better should do). Trichromes are usually thicker & have a mushroom type ball head on the end. Cystolith hairs on the contrary come to a point and are thickest at the base. Tricromes with their heads knocked off may look like cystolith hairs but are still usually thicker, and lack the uniform tapering of the pointy very "hair"-like cystoliths.
Hope that's been informative.
