Did some qb 35 science this morning, main conclusion...every qb35 you add, drops colortemp about 70k.

Given that 96s w fr are currently at ~3450k and 288s w 4x35 are currently at ~2850k, i’d need about 9 or 10 35s to get the 96s to same colortemp as 288s + 4x35.

Both configs currently have similar peaks and similar total areas of red, deep red, and far red, so should be getting similar levels of red-driven photosynthesis.

If i tried to equalize colortemps by adding 35s to the 96 config or reducing 35s on the 288s, i’d end up pushing red spectrums out of sync.

Not gonna make any further red adjustments for this grow.

So, one of the primary differences in the two configs is colortemp...always back to that yuge blue spike in the 96s.....

[the qb11s look like they have exact blues as in qb 96 blue spike..got a few, so in another grow i’ll play with duplicating in 288s]

Not seeing any damage yet due to uvb, if this continues i’ll bump uv to 3/4 of target later this week, then hopefully 100% next week...

Can’t wait to see if these limbo girls can get to a lb each of honey dripping goodnesss....quite a ways to go, still.

288 girls not as affected by recent defol as 96s were...288 girls could take the lead soon, seem to have most momentum at the moment...96s starting to put out new pistils, not sure if this is recovery from defol shock or 2nd flush, seems recovery more likely, given how the 288 girls continue to put out 1st flush pistils.

Back & forth...close game...i like it...here on out should be interesting...

Planning to do a smackdown with @Prawn Connery ’s lights (pay attention, especially if you are in the southern hemisphere)...popped the seeds today, still prob 2-3 months away, but gotta get some mothers going from reg seeds.

If you follow bubbleman, you know where this is going....and then some...

Hey Oro gro I have a question for ya. If you aren’t hitting the correct VPD will it really fuck up your grow? I’m at 81 degrees with 60% humidity with 288 V2’s at 20 days from flip. I can’t bring the temperature down any unless I take the power down on the lights. I don’t have them on full blast, but I am thinking about lowering the power to bring the temps down. I guess my frustration with the VPD concept is, it’s pretty hard on my end to get to those levels although I believe I am hitting levels that I should be in flower (Rh/temp). Does Mother Nature even hit those levels? Are they just guidelines? I’m curious because my plants don’t smell at all. On the stem rubs yes but nose on the buds no.

81F (27c) at 60%, early flower, w white leds?

F#ckin perfect dude!

Too early to smell trichs, no skunky smell means they’re not stressing...

Vpd is about optimal, nature doesn’t do optimal...

As far a defol times. I do my first defol the first day of 12-12. And then again 15 days later, beginning of week 3 when the budlets have formed. Weeks 3-4 the plant will gain all its leafs back.
I didnt have a pic of defol the day of 12-12 but here are pics of day 15 in flower and pics of the plant 13 days later in the 4th week of flower under two 288View attachment 4298838 View attachment 4298839 View attachment 4298841 View attachment 4298842View attachment 4298844
What size space are u running those 2 288s under?

Im in a 2'x2.5' using the xw heatsink, 170 watts on two 288 v1's

@StickyBudHound
The new 288 with reds will be out in a week or two, i hope. Hopefully there is no problems, i emailed hlg and they couldnt release the new 288 due to defects. I call to find out more, they ended up with a couple thousand defected boards. View attachment 4315513
What are the reds (nm, quantity)? Do they have a spectrum pic?

All 4 seeds sunk and started pushing tap root...seeds into rapid rooter, into domed tray...under 2 96s, ~100ppfd, 24:0, 75F...
