Results and bud pics are in:
1061g from a 4x4 @ 700w average flowering intensity. With heat wave and a few non optimal factors my buddy thinks 1300 is attainable based on his previous 900/m results. I think this may be reached but were still at the same plant count and medium volume: for a complete expectation of 50% increase you should really increase plant count and medium volume by 50% but that would get us back were we started with the tent super packed again and growing getting a bit uncomfortable.
It breaks down as 66.3g/square foot and pretty much bang on 1.5 g/w which i find really good for +40w/foot grow as you can always expect some diminishing returns on increasing intensity- higher g/w can of course be reached by lowering the watts and using less blue/uv, but why chase those nrs when you can yield more and higher quality? I think grams per square foot per week pf flowering cycle is likely a better measure.
For the Muricans its comes down to the old 'bout a pound x 2.5 which is great as "3 per light" seems to be ultimate bragging rights.
The pics: first one thru trimming
Next ones were labeled as big secondaries from the topped plants.
And for last, 680 side won by a small margin i dont have exact numbers; this first grow was the dry run and trial without yield and data fixation yet ive done my best to get as much info from it as i can. In any case i always knew we would be looking at small margins between the two sides and i was happy to see that some of my suspicions looks at least tentatively confirmed:
- Straight 660 doesnt look like the optimal redboost; the "Horny" buds are not a positive in my book and and 660 being the culprit has been my longstanding suspicion. I do wonder what would have happened if it was a more pure 680 boost: the 680 side had 2x680 and 1x660 with another peak around 630 due to the narrowband phosphor whites. I did this in part cause i thought a triple 680 could result in some lower density and more stretch due to proximity of 730nm. 680 already have partial activation of Pfr : the same system that 730 activates for the wellknown Emmerson effect. Pretty sure you can drop the 730 from your redboost if you use 680 as substantial part of the redboost. It also seems like it speeds up things slightly as all bench marks steps was quicker on that side. The 680 side also has a little greenboost compared to the other side which is usually asociated with bud density.
Both sides have a similar amount of monos inside the phytochrome action spectrum; but the 680 side had its highest peak around 630 which is outside. It also features a downward slope in the red spectrum similar to what you would find in sunlight ; the same strategy that i had for the blue/uv end (but sloping downwards in the deeper you get into uv).
I wouldnt draw any super sure conclusions here but its good to know that i seemed to have been on the right track in my thinking.
My one surprise was that we couldnt really find any difference in smells between the two sides. I had a couple of grows back with my old grow were i had added 680 as the main new thing and got some very fantastic new smells out of it. I had a few tries with the same cuts under different lighting; but i could never get that volatile fruity yum smell under any other configuration. I guess there was something else playing into that, ill have to rack my brains a bit. One thing different was that in the design of the supplement channel and proportion of monos:
- supplement was both uv and reds all on the same channel - around 50% of each with about 240w of supplement over 900w of warm white high cris. I never added 450nm blue with the uvs which was the case here; that other supplement was a sort of "Hortiblurple" I also think ot may have been less of a "slope" and more of boost just at the end range of par. Anyways this will all be considered and with a bit of luck i should be able to run my own tests eventually, as this is not my own grow i have to consider my new buddies needs and desires for his new growlight and cant go full research mode. I still have some 4ups diodes with iv/red which could be put to use for this. I would really like to experiment with a "hortiblurple" end of day treatment: leaving it on for the last 5-15mins of the day.
There will be a bit of break and prepp time for the next 2 weeks, Spain is hot and summer is busy. Clones needs to be selected and tended to.
Hope you all enjoyed and i would really really appreciate any feedback or questions about the grow- i find that its always beneficial to try talk things thru with others. Let it rip and tell me if you thought something was strange or maybe wrong - its good to get my line of thought questioned.
Finally happy belated 4th of July to all the Muricans, i hope you enjoyed in some way, shape or form. And special mention to my Norwegian Viking brothers for kicking out Brazil in the world cup ñast night- if my experience of what ended up as Bronce for Sweden in -94 is any indication the atmosphere must be electric there: being a small country these things feel really special. Till tops Bedstefar!
and could set up the sosen driver programming software. Easy peasy once i found the right software version - this was the reason we never were able to do it before.
