only if i'm trying different lights and or hanging heights. so not much
What light are you using? What have you found to be a good watt to height to be? I have the light I have at 415 watts at like 20” and they seem to be doing fine. With that app measuring light, the low buds on the front side at down into like the 400/500 range now. I don’t know if closing the tent completely would give them overall better light to or it is what it is. I can’t really read the output of the light with the tent completely closed. I’m going to write them and tell them to put a timer on it and it can takes readings on a timer. Something. That’s what’s nicer about the ones with the cords.

Also. Will not run on my older android cell phone.
Runs fine on my newest, but phone sensor limited to 35000lux. Free app so no complaints.
It's a beta version for android. It's very inaccurate on my 2 identical androids and both max at 22900 lux or 413 par. The lux readings are less than half of those from my lux meter. I've also had trouble with it locking up on both phones and just now got a pop-up saying "One UI isn't responding". Looking at feedback on the app store I see complaints about inaccuracy and the app freezing.

If you go to calibration, it says "Photone is not yet factory calibrated for your device model. The built in light sensors are known to be quite inaccurate and might require calibration. If you don't measure what you expect on a reference, then calibrate."

Everything I've seen says the iPhone version has good accuracy.

just add 10 % house water back to ro will provide sufficient buffer
the standard is 50 ppm carbonate
So I added 10%, which works out to be 2.5 gallons for the 24 gallon system. I forgot to get a EC reading before adding it to the RO water. I’m just going to cut it down to 75% recommended dose. See how it does this week.

I was reading reviews and comments people left about the app. Even on the iPhone version it still froze up on me twice. The reads I’ve been taking have stayed consistent, and at 450 watts 20” away they don’t seem to mind it. If they start bleaching, what’s the first sign to watch for?

leafs have taken over again lol I’ve only been taking like ten off a day and just keep tucking the other ones. They always pop back up by the end of the day.

When I grew in the past I always used Fox Farm nutes. I was looking at Jacks nute line, as I’ve heard nothing but good things. I’m also shopping around trying to figure out what RO system to even get for my city water. I dry ran my setup to check for leaks and all I can smell in the control bucket is chlorine, BAD! I didn’t know if it’s really necessary to get a 8 plus stage RO system with UV. I’ve read if I use RO water I might have to add cal/mag. At the same time I also see if using the correct nutes I wouldn’t need to supplement with cal/mag. If I use Jacks with their recommendation on feeding would I need to add cal/mag to the RO water? I’ve tried researching and can’t seem to find the proper answer for my situation. This is the setup so far, I’ll be using 2 - 250w led QB’s - 4 boards total and dialed down to 200w for 400w total in the tent. Yes, it’s in a kiddie pool lolView attachment 4955854View attachment 4955853
The sun will evaporate chlorine in just a few hours and food-grade hydrogen peroxide will also neutralize chlorine.
