Your Grandpa's Weed or is UV supplementation really needed?

    They say that today's weed is not your Fathers weed, well it's not your Grandpa's either. As an old Hippie that came of age in the early 70's (and who is now a Grandpa) I smoked your Grandpa's weed and it is what I breed and grow. Complex euphoric highs that have no ceiling and last a good while (what we stoners refer to as having legs).

    I've gotten in trouble here before for saying things that make it seem like I'm boasting or bragging when I was actually just tryin to share some info. It was suggested I let others speak about it, so I'm gonna add a few quotes from others but only to make a point as this is gonna be long 8)

    It hauls ass, will get you there, but Rids smoke is like a slow creeping tank that will drive right over the top of that shiny car and crush it with old school steel!"

    Miyagi said,

    "First, with all respect and honesty and not in the least a criticism... Riddleme's buds are NOT magical, mystical things that are better than anything you have ever come across. They are AS good or damn close to the best weed that people who remember the best weed have ever had though and for a lot of people who haven't had truly good pot it would blow away everything they know about weed."

    @Afgan King said,

    "got to meet the legend @RM3 today over at @ttystikk and gonna follow his advice in breeding cause after smoking his strain today all I can say is humbling. Had a whole different type of high I smoke an average of quarter pound week and I smoke a lil Pinner joint between 3 other people and damn."

    Why am I posting this? Well it was prompted by this thread about UV ,
    http://www.rollitup.org/t/adding-uvb-spectrum-to-cobs-opinions-on-this-setup.919962/

    Seems there are a lot of believers and non-believers, like all of the cannabis related topics. So I wanted to share for the community what I have learned from my experiments over many years and as always propose that you, the reader, do experiments for yourself to reach your own conclusions.

    The first thing I will point out/suggest is that if you are one that likes/enjoys couch lock highs then don't do it ! Nothing I grow has any couch lock effect and I have grown many Land Race Indicas.

    I set up my T5 tanning booth so I could mix and match various different bulbs with different spectrums at different ratio's and from doing this for many years I have learned several things ,,,,

    It is a Deep Blue spectrum (think 10,000K finisher bulbs) that grow more trics, they DO NOT increase potency.

    UVA (think Actinic bulbs) Does increase potency but not as much as if UVB is also present.

    There are few bulbs available that actually get er done as far as UVB is concerned for our needs if we intend to duplicate the levels from the sun indoors.

    In order to get the most from UV supplementation Sulfur is required and best used in the form of Sulfates !!!

    I use Potassium Sulfate and Magnesium Sulfate

    "Mel Frank offers this micronutrient formula for high cannabinoid production: Fe-sulfate (5 mg/gal), Cu-sulfate (0.2 mg/gal), Mn-sulfate (2 mg/gal), Zn-sulfate (0.2 mg/gal), Boric acid (2 mg/gal), Molybdenic acid (0.1 mg/gal). Use 1 tspn/gal of nutrient solution, once monthly."

    I have yet to use this but do intend to further experiment with several other sulfates in the future.

    Yet another aspect of this that is disregarded is that seeded weed under UV light is more potent, Yes, I know there will be nay-sayers. but all you gotta do to see for self is grow 2 clones side by side and only pollinate one lower branch on one to see I'm right. As a breeder I always smoke seeded weed 8)

    I've been doing this for years and because I breed I use UV light in all stages of growing. There is not a lot of documented research regarding UV light and Cannabis but please allow me to share the links I have found that are at least useful ,,,,,,,

    So are you saying that you use additional UV yourself? If so I would like to know what additional bulbs you use since HPS and MH wont cut it compared to the sun.

    I grow under 1000 watts of T5 (18 bulbs) and I have tested many bulbs. The ones I recommend are ,,,,

    ATI Coral Plus
    ATI True Actinic
    Agromax Pure UVB (requires caution)
    Agromax UV-A Plus

    Nice.

    I concur with the info. I have used this info for my own growing. I use a similar setup and it gets good results. There are pics in my thread showing the process and results.

    Minimum of 36 inches off the canopy and timed in 15 minute spurts during the 4 middle hours of flower (to mimic high noon sun)

    and the Pure UVB bulb is intense, you need to be able to shut it off if you are in the garden !!!

    Trust me on this !!!!!

    That's just for flower, I don't use the Pure UVB any where else.

    Since your garden is not mine and you are usin COB's I would suggest experimenting for best results as far as times to run it, just be aware that any more than what I suggested will cause damage to the plants

    How many plants do you flower under 1000W of T-5 lights and in what size space? I'm an amateur grower, at best, and it seems foreign to me that someone as skilled as yourself uses T-5. I mean no disrespect sir but I'm just curious.

    The agromax 10,000k+uva is a good bulb to run. ITs not as strong as the pure uv.

    2 single 2 footers of the pure uv @ the ceiling centered ? would that be Over Kill ?

    They both come from the sun and both have an effect on our plants, even the Pure UVB bulb has both

    I think UV-C is also important, not for buildings trics but for keeping spores (especially damn PM) at bay. They use it in hospitals to filter the air.
