UVb an experiment

[khyberkitsune]

when oldmac was younger...rocks were still soft....:rastabanna:....

I just realized you had the TN flag. Hope you didn't have my misfortune of living in Memphis for fifteen years!

As a side note, good joke! I had a good chuckle from that!

have you read the entire thread?

Yes. Did I miss something about that? I read the 'last few weeks' bit on another forum.

quote, well this is an experiment thread, hence the experiments with UVB. plants in nature get UVB more than just the last 2 weeks of flower, correct?

Outdoors, they get it from day uno.

Indoors, depends on the light type. LED, nope, not unless it's been designed that way!

yeah i got it khyberkitsune, i was being sarcastic towards Permabaked.

True but don't people only use MH bulbs for the last couple weeks of flowering because of the additional UVB it provides? Maybe he should add another set of plants to his experiment that only receive UVB at the very end.

people only use MH during the last two weeks of bloom because they get bigger yields with HPS and no other reason. i've read a case study where a grower grew two identical crops, one at 4500' and one at 9000' elevation. the crop at 4500' had about 25% more yield, but less trichs.

Yeah that!

Shake knows!

And, I have seen capitates get decapitated by the UV in sunlight.

They cook down to tiny brown specks and blow away.
You can watch it happen with a 30X loupe.
<Requires a lot of patience>
How fast that happens depends on several variables, but the most influential is intensity.

@HS:
Shoulda used the sarcasm font a few posts back, yah?

Aloha nui,

fa sho! i must have been too :stoned: to find the damn thing! those capitates had me decapitated....or i guess it could have been too much UV to the brain?! :wtf:

I was just listening to Bocephus, and "All my rowdy friends" just came on while I got to this thread.....you know who I thought of? They all seem to be on my porch, or at least passed by. Let me just answer a couple of things here:

@knna; This experiment, like my first, is based on observations and tasting is based on subjective experience. Would love to see THC %, but that even done by a lab is subjective and can be manipulated since it is % of the amount of material submitted. Better to just go observational.

@Rusty; I only mentioned the apricot pits to explain the strains nickname. I didn't want someone trying to look up "apricot" and going WTF. I have seen many holistic and alternative medical techniques used for cancer, but that becomes an individuals choice and an area I steer clear of. BTW the UVb was used for the entire photoperiod, 18 hrs during veg and 12 hrs during flowering.

@Permabaked; Let me just cover the experiment quickly, 1 grow chamber is UVb from veg to flower, 2nd is UVb for flower only and 3rd is no UVb at all. I've already done an experiment using UVb for last week or two, and I found it will turn trichomes from cloudy to amber. It's pretty much what I do in my personal grow.

And for everybody else, glad you have enough interest to stop by and see how an old man entertains himself.
