copyright 2003 George Grass rev. 2004 2005 2007 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 capi…

from http://h1.ripway.com/opticspdf2/summary.html MARIJUANA OPTICS SUMMARY What It All Means Of the three glandular trichomes produced by drug-type marijuana, only the capitate-stalked glandular trichome in the presence of the UVB photon has the phytochemical capacity to produce the amount of THC associated with euphoria and hallucinations. The capitate-stalked glandular trichome is triggered into growth on the floral bract and concomitant leaves either by fertilized ovum or by photoperiodically-induced parthenocarpia. A female plant grown from a seed that was the result of an ovum fertilized by pollen from a male plant (Sativa or Indica or Thai or Me…

copyright 2002 Joe Knuc rev. 2004 MARIJUANA OPTICS An elaboration on the phytochemical process that makes THC The resin exuded by the glandular trichome forms a sphere that encases the head cells. When the resin spheres are separated from the dried plant material by electrostatic attraction and placed on a microscope slide illuminated with a 100W incandescent bulb, they appear very dark when observed through a 300X microscope. Since orange, red, and infrared are the component wavelengths of incandescent light, and since the absorption of light makes an object dark or opaque to the frequency of the incoming wave, one can conclude that these wavelengths are probably…

Anyone ever actually used anything like this before? http://www.accenthydroponics.com/prod_info...0soak_info1.htm It "binds high nitrogen to Ethylene Acid (feminine) which stimulates the seeds to encourage a tendency for the plant to become female". Sounds like it has a two-prong effect ... "Stimulates the seeds to encourage a tendency for the plant to become female. This results in more flowering sites and overall greater flower development". I've also heard of people leaving their seeds in an airtight container with banana peel before germinating them to achieve the same effect. The only other thing similar that i know of is Sensa Soak which is pretty much the same…

Ive recently got into bonsai plants, i reckon theyre cute as kittens and i've started training them with the aluminium wire that was supplied. Up until now i've just used strings to tie down my mullies like i guess most LST'ers do, but im considering trying some wire on one tonight. Does anyone do this/done it before?? I can't really think of any disadvantages when compared with string tie-downs, but the advantages that i can think of: - complete 360-degree control vs strings where youve only really got vertical control - no need to tie down to anything like screws in the pot - should be able to get better light distribution to more parts of the plant - you can make …

This is my 1st attempt at a hydro setup and would like your opinions. I have a number of 5 gl buckets. That's 18 plus liters. the bucket is 300 mm across the top and 350 mm tall. Basic bucket right? They are white and I plan to paint them with black krylon paint supposedly this stuff is designed to adhere to plastics. whether it is anough to keep light out is still unknown. I want to set these buckets in line with a large single drain manifold leading to a central nutrient sump and a pump feeding a supply manifold that will tee off at each bucket. Both the drain and feed manifolds will be rigid pvc the short sections of both the drains and feed lines between…

Was chatting to hydro shop dude the other day not about how to make profit, but the easiest way to grow. In the course of the conversation he told me a story of a guy who came in, one of the few he knows of that have 'actually made it' using hydro. This guy only bought 4 inch cubes and Optimum nutes, Flower only. Seems he had a shed with a large concrete slab beside the shed, out of town. Shed was set up to veg only, but flower nutes were used the whole life cycle from clone to flower Clones were taken continually and put into the 4inch cubes The cubes sat in trays on trolleys and were wheeled outside at 3 weeks The rooted clones began flowering straight away and were flo…

I've been fucking around with the idea of growing in paper towel, since you can sprout them in it, why not grow them in it? Well I have a healthy crop, which is the strongest skunk I have ever tried in my life! I think this tops white widow hands down. Step 1) get a water tray/water troph Step 2) get some pots to fit Step 3) Put paper towel in, enough to fill it up, not too dense and not too weak, just enough to fill the whole pot. Step 4) Put the seeds in with some thrive pellet fertilizer, Step 5) Fill the water tray/troph, AND FUCKING LEAVE IT! now and then top it up. The idea is that the plant gets plenty of moisture, and the water allows you to come back no…
