MARIJUANA FLOWERING

 

N35Lat

 

This study uses artificial light to replicate the daylength during summer and fall in Afghanistan when marijuana goes from vegetative to flowering plant and on to seed set, if pollinated, or parthenocarpia if not. Although the study uses 4000K metal halide HID light or 6500K fluorescent and 2845K incandescent light during the vegetative and flowering photoperiods, UVB photons will have to be added to the light stream of the photoperiod after the floral bract ovum has been fertilized or has become parthenocarpic in order for there to be fully realized THC in the exuded resin sphere of the capitate-stalked glandular trichome.

 

MARIJUANA VEGETATIVE PHOTOPERIOD

 

4000K or 6500K light

 

ON: 5am OFF: 11pm

 

06:00 hours darkness

 

30 Seeds are planted so they germinate early in June. When the seedlings reach five nodes in growth, 21 are transplanted to one-gallon pots and the vegetative photoperiod continued until November 1st. On that date, the photoperiods begin to be adjusted weekly. From July 5 (14:30 hours) to September 12 (12:30 hours) the daylength at S35Lat is shorter by an average of two minutes each day or about 15 minutes a week.

 

When the plants show their sex, isolate the males from the females to prevent premature pollination.

March 12th is the latest to bring pollen shedding male plants to outdoor hetrozygous female plants to begin pollination if fertilized ovum is the route chosen to trigger the capitate-stalked glandular trichome into growth before the autumnal equinox. But because the

 

effect of the simulated photoperiods is not seen for a week, December 30 will more closely approximate the floral bract development of March 12. Integrate the sexes. Shake the male plants occasionally to release pollen and then blow or fan it toward the nearby females. Marijuana is a wind-pollenated plant so it will be necessary to simulate some kind of breeze to get the plants thoroughly pollenated. Pollination of hetrozygous marijuana always brings in an earlier crop than will hetrozygous marijuana parthenocarpy. But if parthenocarpy is the route chosen, then the male plants are turned into hemp as soon as they show their sex. If the UVB photon is present in the light stream, approximately five to six weeks are required for the majority of the exuded resin spheres to contain fully realized THC once the capitatestalked glandular has been triggered into growth. This is why the author recommends, after pollination or onset of parthenocarpia, the plants be moved outdoors each day from 9am to 3pm into a structure whose covering will hide the marijuana but let the UVB photons in sunlight through to energize the phytochemical process to make fully realized THC. The manipulation of the photoperiod to have the capitate-stalked glandular trichome make its appearance when the level of UVB is intense enough to cause a naked caucasoid to become sunburned in the northern latitudes above the Tropic of Cancer is the way to go for the medical marijuana patient who wants more than a placebo effect from the harvest. Sunburn is a key indicator that there are enough UVB photons in the sunlight to make fully realized THC. If the outdoor scene is out of the question, then specialized incandescent

 

bulbs that can project 25 to 50 μW/cm2 of UVB for a distance of up to 12 inches can be used instead with good results. The infrared wavelengths from this bulb make it difficult to get any closer than eight inches or so to the foral bract cluster without burning; if the bulb is moved further away than 12 inches, the inverse square law comes into play and the UVB μW/cm2 is so small as to be useless for the purpose of fueling the phytochemical reaction to make fully realized THC.

Marijuana pollinated December 26th may have a majority of seeds ripe in some of the floral bract clusters. Clip the most likely candidate and check it out, leaving plenty of wood with the floral bract clusters to slow the drying. After removing the basal leaves and cutting the tips off of the remaining leaves, place the trimmed marijuana in a paper bag (grocery type). Leave the top of the bag open. Place the bag on the front seat of a car with its windows rolled up. Face the car South so the sun comes through the front windshield. When the marijuana is dry, check the number of ripe seeds; then smoke the dried floral bract cluster, without the seeds, in a water pipe with a clean bowl and screen to see if harvesting should begin. The reason a clean bowl and screen is recommended is because igniting the gunk left behind from previous smokes will trigger a tremendous cough reflex, and this will definitely interfere with the uptake of THC. Metal bowls and screens can be cleaned rather easily of this gunk by holding them with a pair of pliers

 

and putting them in the gas flame of one of the burners on the kitchen stove. The residue gunk burns with a bright yellow flame. Once the flame and smoke are gone, the bowl can be cooled off with cold water at the sink and the inside of the bowl wiped dry with a paper towel which will also get the soot out.

The majority of seeds in the pollinated marijuana should be ripe by

 

now and the harvest complete. Parthenocarpic plants not ready to

 

harvest yet but are showing "grease" on the enlarged floral bract and concomitant leaves.

The parthenocarpic hetrozygous marijuana is ready to harvest beginning September 1st.

Marijuana Flowering

[bufo marinus]

Hmmm interesting Uncle Authur, seems like a bit of rooting around. I'd like to sample the buds from this type of wavelength exposure and see if it's all he claims. Good post

[Uncle Arthur]

This is the light set up they are talking about minus UV lamps

[everest]

sounds alright for me , i'm always a bit late putting me lights on

 

ev

[loylty gets u nothing]

so there is a place for incandescent bulbs in growing..

interesting read..thanks for sharing..

listen wats australias coordinates??

latituden longitude etc??

bil

[mull]

That is very interesting Uncle.

Still trying to wrap me head around those light hoods tho. The smaller one has 28 by 100W light bulbs, on either side of 4, 1000W Mh's? Thats some killer heat to extract.

 

Also, any idea if clear lazerlight filters out uvb?

 

Keep up the study mate

 

 

Bill - aussie is big mate, but we sit roughly including tassie from 42 - 10 deg lat / and 110 - 154 deg long

Tropic of capricorn just below 23 lat.

[Uncle Arthur]

listen wats australias coordinates??

latituden longitude etc??

bil

 

Coordinates for various places in Australia

 

Melbourne S 37 degrees 46 min latitude

 

Albury/Wodonga S 36 degrees 4 minutes Latitude

 

Sydney S 33 degrees 52 minutes Latitude

 

Nimbin S 28 degrees 35 minutes

 

Brisbane S 27 degrees 38 minutes

 

Cairns S 16 degrees 54 minutes

 

Darwin S 12 degrees 42 minutes

 

Alice Springs S 23 degrees 44 minutes

 

Perth S 31 degrees 57 minutes

 

Adelaide S 34 degrees 55 minutes

 

Hobart S 42 degrees 46 minutes

 

Canbera S 35 degrees 16 minutes

 

I have only given coordinates in degrees Latitude as that is what is relevant to us. If more detail is required let me know. Also if anyone wants a place I haven't included I can give you acuracy to your front door. (If you are silly enough to give me your address).

thanks man

wat about the gold coast say tambourine mountain

and the lower areas..southport sufers paradise??

and wats the 38min and min readings mean??

i never payed attention to that stuff in school..

bil

[Uncle Arthur]

Southport S 27 degrees 58 minutes

 

Going shopping more later

 

cheers

[loylty gets u nothing]

woow

man tyhat was quick

thanks very much

hopefully now i will be ablt to plan out a proper outdoor grow

apreciated royally and much mojo to u
