OK, a little confused on the hairs conversation, but if your talking about that plant in the picture then.......

I read in one of the grow books (not sure if it was the bible or one of my others) that trichomes do form on your plants throughout growth, but are not THC. There are different types that are present. I found this tad bit of info. for ya. Hope it helps! :thumbsup:

Bulbous trichs maybe?

Trichome - Trichomes and cannabis

Trichomes evolved on cannabis to prevent herbivory/parasitism by small insects. In the wild, insects landing on a cannabis leaf become adhered to the trichomes causing death or lost time (see sundew) and in addition will absorb the cannabanoids and, so intoxicated, experience increased rates of predation and loss of will to escape. However, the intercession of man in the natural selection process has rapidly accelerated the favoring of genotypes that produce copious amounts of THC laden trichomes. In addition, THC has very high UV-B absorption properties, thus cannabis evolution may have favored the evolution of genotypes that produced these THC laden capitate-stalked trichomes as a built in 'sun-screen' for protection against UV-B light rays. The dried trichomes of cannabis used for smoking purposes is called kief.
Trichome - Types




  • Bulbous: The bulbous type is the smallest (15 to 30 micrometre). From one to four cells make up the "foot" and "stalk," and one to four cells make up the "head" of the gland. Head cells secrete a resin - presumably cannabinoids, and related compounds which accumulate between the head cells and the cuticle. When the gland matures, a nipple-like protrusion may form on the membrane from the pressure of the accumulating resin. The bulbous glands are found scattered about the surfaces of the above-ground plant parts.


  • Capitate-Sessile: The second type of gland is much larger and is more numerous than the bulbous glands. They are called capitate, which means having a globular-shaped head. On immature plants, the heads lie flush, appearing not to have a stalk and are called capitate sessile. They actually have a stalk that is one cell high, although it may not be visible beneath the globular head. The head is composed of usually eight, but up to 16 cells, that form a convex rosette. These cells secrete cannabinoids, and related compounds which accumulate between the rosette and its outer membrane. This gives it a spherical shape. The gland measures from 25 to 100 micrometres across.


  • Capitate-Stalked: Cannabinoids are most abundant in the capitate-stalked gland which consists of a tier of secretory disc cells subtending a large non-cellular secretory cavity. During flowering the capitate glands that appear on the newly formed plant parts take on a third form. Some of the glands are raised to a height of 150 to 500 micrometres when their stalks elongate. These capitate-stalked glands appear during flowering and form their densest cover on the female flower bracts. They are also highly concentrated on the small leaves that accompany the flowers. The male flowers have stalked glands on the sepals, but they are smaller and less concentrated than on the female bracts. Male flowers form a row of very large capitate glands along the opposite sides of anthers.

Trichome - Active ingredients


  • THC: delta-9-tetrahydrocannabinol and delta-8-tetrahydrocannabinol - THC mimics the action of anandamide, a neurotransmitter produced naturally in the body, which binds with the cannabinoid receptors in the brain to produce the â??highâ?? associated with marijuana. THC possesses high UV-B (280-315 nm) absorption properties.


  • THCV: tetrahydrocannabivarin - prevalent in certain South African and Southeast Asian strains of cannabis. It is said to produce a â??clearer highâ?? and seems to possess many of the therapeutic properties of THC.


  • CBD: cannabidiol - previously believed to be psychoactive, or to contribute to the high by interacting with other cannabinoids, conversely the most recent research indicates that CBD has negligible effect on the high, it is however a strong anti-inflammatory, and may take the edge off some THC effects, such as anxiety. CBD as a non-psychoactive cannabinoid appears to be helpful for many medical conditions. CBD biosynthesizes into cannabinol (CBN) & tetrahydrocannabinol (THC).


  • CBN: cannabinol - a degradation product of THC, produces a depressant effect, â??fuzzyâ?? forehead.


  • CBC: cannabichromene - non-psychoactive , a precursor to THC.


  • CBG: cannabigerol - non-psychoactive, hemp strains often possess elevated levels of CBG while possessing only trace amounts of THC.
Italiano715 Reviewed by Italiano715 on . Trichs on seedling??? Whats up guys... got a few questions for the vets. Im on my third indoor grow and popped some dank bagseed beans from many years ago. I just got home for lunch and went to check on them... One had some weird looking leaves from the start so I was looking closer and noticed some white on the leaves. I grabbed my 420 scope type microscope and checked it out to see if it was mold or pests. To my amazement they are some trichs on the leaves! I dont know if this is normal but I sure havent Rating: 5
