Hi, 

I am at end of week 3 of flowering my sour Diesel plant.  Just a question of how much do you think I should prune away at the the bottom?  Plant is about 2 feet tall.  2000W COB LEDs (450 from wall)

That is some stretch! Damn lol. To your question, it's totally up to you, haha. It looks like there is plenty of airflow, and the more solar panels your plant has to make energy, the better. I usually take off any of the lower branches/leaves that are buried under the foliage and aren't able to get any good light exposure/are hindering air flow. But again, it looks like the plant is getting pretty evenly lit from that pic. If it was me, I don't think I'd take any off. Based on that pic.

Only thing is, since you have that crazy spear-like main growth stem shooting out like that, the lights won't be able to get too much closer to that lower bushier part of the plant. The lower buds will probably be smaller and less dense than the top main cola there.

Thanks @TempleGrower.  Yeah this is the first time having a crazy stretch but also the first time putting into flower without doing any LST.  Funny sewing them next to the Bubba Kush which has almost not stretch at all.

I have a PAR meter and read anything over 1000 I would need C02.  But if I aim for the top bud at 1000 the lower growths will have quite a lower reading.  Would the higher Umols hurt the flower as long as it's not being burnt by the light?

I think you'll be okay as long as you aren't seeing any light burn, like you say. There is a chance of some bleaching on your top buds though, depending on the light. I have a bit in my Glueberries I have going.. only 1/3 plants though and they're all the same distance from the light. Kinda odd but, yeah, watch for that. It's only happened to me using the Mars II series though.  I'm not sure if bleached bud is really bad though either, other than looking weird (kinda cool actually). It still smoked and tasted great the last time it happened to me so, yeah.

But yes, to the original question, the more light the better.

And CO2 uptake is more of a function of temperature I think anyways, not so much affected by light intensity. Here's a nifty chart/blurb from Jorge Cervantes's Cannabis Encyclopedia about CO2 enrichment:

CO2 Enrichment
CO2 Enrichment Graph

And also FYI, the Sun's PPFD is right around 2000 umol/m2/s on a good clear day at its peak, so that's what I try to mimic in the tent. Never will but, one can dream... haha 😎

Ok awesome thanks you very much @TempleGrower.  I will have to see what I can get away with with these lights in terms of distance.
