I use it and I’m really happy with it. The in-app buy is about 5€, you just have to chose which kind of light you use. Totally worth its price

I have used the free part of it. It works, but lately I know the light I am using so have not needed to check it

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?

Swapping day/night light cycle during flower
Day 22 of flower. Lights are on during the day, 8am-to-8pm but we need to switch to 8pm-to-8am to use the colder night air to cool our lights without using a/c. Would it negatively affect the plants at this point in flower to give them 24hrs dark & completely swap light cycle?

11/13 for flower
I need my grow to finish flowering ASAP, due to extenuating circumstances... I’ve read that flower can occur faster under 11/13 with some loss of yield. Does anyone have experience here? How much will yield and flowering time be influenced?

2x viperspectra xs 1500 150watt ? Does the power of 2 lamps add up together?
Does it make sense to buy another Viperspectra xs1500 with 150watts? So my question is, if the power of 2 same led lamps add up together?

Should I lower my light during flowering?
I'm at 24 inches away now, should I lower the light now that she's in full bloom? I went with the recommendation of Mars Hydro and burnt up 3 seedlings as a result. Sadly I only have one bean left of my Fastbuds over this crucial mistake. Running a Mars Hydro SP 250 keep at 36in.

Stretchy seedlings...worried!
Hi, I have 5 seedlings on day 7. 2 of them are going fine but the three from ditch passion were very stretchy though. Likely due to having the light to far away. Take a look, any advise would be great. Cheers all!
