Ok it was a little confusing around page 4. You showed the 90 cri bigger than the 80 cri but You said something like we will know in 10 weeks. Well damn that is a big difference between the two cri.
Your side by side is interesting. I think the only thing it proved was that 90 cri vegged much better than the 80 cri. With better root structure and size in veg you are bound to get bigger nugs right?
There is cree-nis and now cri-nis envy.
It seems like there is so much unknown about lighting and canna that it feels like throwing darts in the dark.
The next best thing might not actually be as great as it is on paper.
We'll need a new lighting term or 2.
The GSR(grow sativa rating) is...
If you run them hard and manage to maintain 50% eff. Then they will put out 2.43 umoles/j/w. If a DE has a PPF of 1700 then you will need 700w from the QB.
That is comparing the data. It is said that the QB grows better and you don't need as much power so it is hard to tell exactly.
I would...
Well damn I've been sleeping on this new wave LES movement using HPS. I'm waking up real soon. :sleep: I'll be doing 675w of COB over a 4x4 to see what happens. Probably end up recycling the raptors.
Are you trying to see how few watts it takes to produce well?
Would be interesting to see what 20 watts per sqft of QB does.
Oh you might be talking about the QB304 model. If so scratch what I just said.
