answered grow question 2 years ago
i would recomend maybe 25% and keep it 12" at seedling to keep from stretching then up it 50-75% @ 18" veg and then crank it to 100% for flower and use the photone app or get a par meter (if you have the money) to check ppfd and adjust height

Can rotating my 12 hour cycle back a few hours over the course of 3 nights harm my plant mid flower?
If i were to manually flip my lights on and off an hour early for 3 nights to adjust my 12/12 from 9am-9pm to 6am-6pm would it be detrimental to the plants? They are in the 5th week of flower. Rotating back 1 hour each night

Light analysis??
I used the photone app in order to get these numbers that are pictured below ! I’m going to research them but I’d thought I’d share them anyway.

Lighting coverage
Will my viparspectra xs1500 have enough coverage once these plants get larger? Or will I need supplemental lighting? And if I do need more, am I better off getting the larger model, or just getting another identical unit so that I have 2?

LED distance to plant advice
Interested in how close I can get my 630w LED with a rating of 2.7μmol/W and 1700 PPF to my canopy. I had it hung 48cm (19 inches) on 380w and just upped it to 500w day 8 in flower. Does this sound too close at 500w or is this ok? Temp is 25C (77F) humidity 55%.

White and blurple led in same tent?
I recently upgraded to a TS1000 for my flower tent, and am waiting on an SF1000D for my veg tent, and now have a tmlapy “1500w” blurple sitting around. Would i gain anything running the blurple and ts1000 in the same tent? Or is it not worth the extra energy consumption

Lux Meter Apps on Smartphones
What are your thoughts on Lux meter apps? The app on my Samsung Galaxy S10+ is showing 16,600 Lux at the tops of the seedlings, and converting that to a rough PPFD shows 222.55/umol/s/m². Reading more, 15k-45k Lux and 200-400 PPFD is good for early veg. What are your thoughts?
