Hi again,

In regards to your questions GH.

1 - That's most likely due to the same reason that I highly recommend that nodody attempt growing indoors with highly powerful UVB light sources of any kind. I have no doubt that the lawsuits that would pursue the manufactures would be countless if they produced HID 'sleeves' that were without a UV filtration coating on them for the mass markets. After all it does not mean much to them anyway as their main dollar comes from the 'commercial and street 'lamp'' industries, and not the horticultural. Keeping in mind that the high-emitting UVB tubes are not made for any applications where there is exposure to human skin or eyes at all. They are contained within a housing that emits the light only in one direction which minimises any stray light emissions, and they all come with a manufactures warning that they are NEVER to be used by anyone, or ini the presence of anyone, who is not completely dressed with UV protective clothing and eyewear.

2 - Not off the top I don't. But if you're intrested, it is only a matter of contacting the manufacturers and asking for 'spectrual emission graphs or charts' for their HIDs - they can easily be emailed as attachments. MH always produce more of the UV spectrum, this is why I prefer a 1000WMH and a 600Whps for my small room grows. For larger or multi light grows I would recommend a '2 to 1' power ratio of MH to hps, respectivly. The MH also aids in reducing stretch compared to hps.

But if it's a top quality indoor HID setup you're after, then I would recommend you have a look at the Gavita systems, and especially the P.L.Light Systems. They make the best horticultural HIDs in the world, but you have to buy their entire system, not just the bulb. They each have their own homepage on the inet and are sold by many different suppliers worldwide, here is one of their countless suppliers:

3 - "Are you saying to run only the red incandescent during the first and last hours of lights-on?"

YES, as the sole source of light for the 1st and last hour of the entire life of an indoor grow - both veg and flower.

"And the UVB flouro(s) during the entire light-cycle?".

The UVB fluros are a supplemental source to the HIDs and are run in conjunction with the HIDs only during the period that is within the 'first and last hours of lights-on', after and before the incandescent lights are run. Rememeber also, that the transition between the incandescent lights and the HIDs+UVfluros is a MAKE-BEFORE-BREAK scenario that assures the plants are not left in darkness.

4 - Capitate-stalked glandular trichomes only exist on bracts that are seeded, as the article by Marijuana-optics outlines, as do other sources. When fully realized, it is the most potent form of triclom.


"I've not checked out the Heraus website yet, for the wattage sizes of their MH lamp(s), but thought to ask you what wattage their UVB MH lamp is? Can you get a 400w lamp, for example, with a total UVB output of 10w or less? And what distance should such a lamp be kept from the canopy?"

You're getting into ground that I best advise you not too - ie intense UVB grows indoors. 10W is a massive amount of UVB and would be extremely dangerous. For information purposes only, I can tell you that HIDs can be ordered/bought without any UV protective coating on their sleeve. But once again, it too requires the use of full protective clothing to use.

"Well, I think I might just be crazy enough to try it, so I do appreciate the guidance!! It should be possible to create an automated window each day, when the UVB lights turn off and on, during the lights-on cycle. As a safety measure, though, against error, I'd wear protective clothing, super strong sun-screen, and UVB sun-glasses. The aging effect on the flower room seems like a small price to pay for high-quality trip-weed."

OK.

I am going to have to pull stumps here as I can see that there are some who may go ahead and try this UVB intense indoor grow. In all seriousness, if you are willing to go to such lengths to grow it, then why not do it outdoors? It would be safer, cheaper. Spend the money on stealth and security for your outdoor enviroment, is the best advise I could give anyone.

This is nothing against you or anyone else GH, but from now on I would only feel right about responding to questions that are not in relation to high intensity UVB indoor grows. Apart from the safty issue, that is not why I posted this issue to begin with. So I hope you don't mind.



"If growers choose not to use UVB lamps, like the Heraeus MH, for example, and other UVB supplements at their disposal, it seems logical for them to only use the HID lamp which has the highest UVA output; since it is this UV light stream that accounts for the potency of indoor bud;"

Yes, that's right. Better some than none.

"While UVA does not "produce fully realized THC," it must be producing some THC, or all indoor bud would be pure shwag. That brings me to my next point, concerning what you wrote in your opening post, about it not being in the genes: "It is not the genes - it is the means by which it is done. Irrespective as to what all other works/text and seedbank-advertising has said or outlined about it till NOW." "

The term fully-realized has more to do with the concept of fully-psychoactivated resin, that can only be accomplished under the immense spectral output of the Sun, rather than how much THC the resin has. ie it's got it, or it hasn't. It has been found now, that along with other issues, that even the ratios of the THCs, CBNs/Ds etc also play a large role in the overall potency of the resin, not just the THC percentage. But I do beleieve that if we start to look at those aspects and others of the overall potency of the resin, we would require another thread. That is not really the reason I posted this thread either. Sure genetics will govern even the level of different strains's fully-realized potencies, in that some strains when fully realized will be more trippy than the level of trippiness that others have. But I was attempting to point out that all decent, let alone top, cannabis strains are capable of producing tripping weed when grown under the right conditions and enviroment. Tripping weed is just that, as is good weed which isn't of tripping standard, if you know what I mean. IOW, you either have it, or you don't, and when you do you soon realise that whatever strain it is, it's good and it's similar(ie tripping weed is tripping weed). Some a little moreso, some a little less. But what I'd like the newbies or those who don't know to realise, is that the differance between most good to excellent strains is not that vast. A strain either has what it takes, or it doesn't, the rest is up to the grower. Nobody will sell or give you a seed, that no matter how you grow it, will end up being tripping weed - even though some advertisments indicate otherwise. With cannabis strains I have found that potency levels can be fundamentally classified into no more than 3 grades of potency - low, good and excellent. The low grades of potency level cannabis is no longer available from any decent seed suppliers today, only from the streets. As all seedbanks are in it for renewal business and not just the one off sales with every customer. So if it is a reputed bank/supplier you are dealing with, then you will only get one of two types of strians in regards to potency - good or excellent. Either will produce tripping weed if grown correctly.

One last thing I should add is that the MarijuanaOptics article does not cover other aspects and light bandwidths of the Sun's emissions that may also play a role in the resins activation process, that may occur in conjuction with the known UVB aspect of the realization. Like the ultra low Gamma-rays, x-rays and ultra high RadioFrequency-level waves that are emmitted onto the earth. But the means to even test this scientifically, on its'/their effect on resin activation, may not even be available or developed yet. So the future may still hold other keys that we are completly unaware of currently. Suffice to say though, that so far UVB rays are the most effective in the realization/activation process, though perhaps not the only rays.


Hiya Lucifer,

From what I know, photons do not have any form of polarity including electromotive. But I can see what the old-bloke was trying to say - we can't beat the Sun, that is without a doubt.


Take care.
