Death by Radiation

Skunk, you have provided another valuable link for us to consider in a specific way - Cooling of the cell structure!:hump:

The plants responded upon repositioning of the fan, maybe that was it and not the 'stabilization' of the lamp.

Make sense?

Yes, perfect sense... bad judgement on my part. Although if I had this experiment to do all over again I think that a green light would be beneficial, obviously of a similar minimum 300w intensity.

I never considered a uv lamp as a source of heat, but of course it does make tons of logical sense. You had approx. 300w within inches of the plant, and we all know what happens when the lamp get too close to the plant.

IMHO, I believe the plant kind of went....ohhhhh uv and then stabilized, as much as it could, given there are substantial portions of the light spectrum missing. Do you think the veins of the sun leaves are thicker? or more pronounced? I've noticed that mine appear to be that way.

No... I think maybe your fan-leaves are just enjoying the fresh air. But in saying that, I only have a different strain to compare with... atm the NL have broader veins on the fan leaves and they are under MH.
 
I've been away for a few days, and am working on a new machine (computer), this journal is locked up in my other HD... and I can't be bothered atm to pull it off there. If it was easy I'd do it now, but I've already tried the HD as a slave, a master to the new machine... everything. The new machine does not like the old HD for some reason.

If I still haven't done it in a couple of days I'll update this to where I am now, which is two weeks flower. The male (skinny) is dead and his pollen collected, the female (fatboy) has developed purple pistils, only the odd one or two... but they are most definitely purple pistils here and there.

SKH...

How are they doing now?

The male (skinny) is dead, and his pollen collected. Fatboy is 2 weeks into flower... she is severely stunted in comparison to the Northern Lights I have in the same flower area.

Fatboy is flowering beneath the UV and the NL are beneath a 400w HPS. The two lights are set very close together. The NL have stretched considerably, whereas Fatboy has not.

Fatboy has developed purple pistils here and there. I'll upload a pic tomorrow to better explain things.
 
In these pic's I've tried to show the relationship between the NL and the AK.

One of the NL is in close proximity to the UV bulb, but has not suffered at all. The AK is stunted and with tighter spacing on the internodes.

Although these are different strains it is clear that the UV has a massive effect on growth patterns during flower. Indeed if the right measure of UV can be obtained during then it would seem to be of huge benefit if trying to keep plants small.

The AK plant seems to have no desire to stretch towards the HPS. Certainly there are different genes at work in this plant's photosynthesis.

There's only one pic of the NL, the first pic, you can just see how tall the NL is compared to the AK.

The AK also has purple pistils here and there but only on the flower heads at the top facing the UV, lower down the plant the pistils are all white.
 
I noticed the fan leaves on the NL
are taking on that waxy appearance
as well... Was the light a 300w UVB
lamp? Interesting.
 
i thought this was an old thread.
i started a plant on the same day as yours and yours is miles bigger.
what nutes you using?.
 
Yes, i started the thread then, but the grow was already done... I was merely cutting and pasting from my own journal.

I've got a new machine so have lost the rest of the veg journal. I'm now 2 weeks into flower and have caught up with myself.
