in our country every school has these co2 meters and they try to keep ppm's under 800, brain is not working full capacity over these levels and in schools its important, but yeah i have had headaches a lot before i started to ventilate my rooms and when i had visitors very often people...

yes overnight in that room im sleeping it gets even to 2K +.. you cant imagine how small the rooms are :D when i have visitors it gets to 2K in 3hours when we are sitting in that room, and you can feel the bad air quality, its so dense, i usually open windows when i have visitors, its a mess...

the device cost 300usd - its a reliable device, one of the best on the market (Aranet4), i trust it! And yes, you cant imagine how bad the ventilation in my home is, and yes sometimes i have headaches.. so i took this device to test how often and how long i must ventilate my home/rooms not to...

it is, i have a pretty expensive co2 measurer, i asked a friend to give it to me, tested it in my house, the ventilation is bad there..

Thanks a lot! i had this (Uni -T UT383 or the Bluetooth version) device in mind after stumbling up on this y-video.. but then in his comments later he mentioned that the correct conversion rate for this device is 0.017 in case if i have also RED IR leds..any way so i will use this conversion...

yeah i tried it on Android phone, it is not useful at all.. but for iphones it really kinda works, i watched many y-tube videos. lucky iphone users.. :D

yes , there is a plenty of co2 because the room is small, all rooms actually are small and im living in there. When i ventilate the rooms for a long time next day co2 ppm on the ground in the growtent is already up to 1200-1400ppm, so with these co2 levels the plant can eat more heat and light...

it has a map, but it doesnt tell any story, the map , the radings are from one height and if i want to adjust or dim the LED, the measurements will differ, so i dont think i can use the manufacturers data in all cases..

yeah i got it, its also kinda hard tevery time o grow different plants, they all need something different..i should choose one strain/genetics and get familiar with it..

Hi, i had the idea to buy a cheap LUX meter to calculate the aproximate DLI and PAR. I see people are doing that. Some guys alrady calibrated some meters from The apogee PRO devices. ChatGPT says he can calculate the data for me, it just needs the LEDs SPD data and i have it. My LED is Mars...

yeah when i gave them the 1L each, the next 2days they just exploded and the stems are pretty big now also. tomorrow i will give them another 1L (i will let 2days pass in between again) i will continue to give them the same 30%, then 50% and stop by 50% will take a look for a week how she reacts...

2days ago i watered with 1L each, this is how they look now.. The leave tips ar burnt from the LED i think, didnt check the hieght and the LEd was too close, im sure about it, but i dont see any spots on the new upper leaves now.. looks pretty good to me now.

thanks a lot, i flushed it with plenty of water with runoff, will see how it will react to that the next few days!

im worried mostly about the dots on the leaves, but im underwatering her and she grows it just means she doesnt get anough nutritients from the roots right? without water for the roots the plant cant feed herself.. that would be the logic in this case.. hmm..

the first to weeks i barely watered it because it was so small, a seedling you know? like 25-40ml in the first week from sprouting, 2nd week 50-75ml, 3d week aprox 100ml in that 3gallon pot, and now when its bigger i do aprox 300ml.. trying to do 1day in between and then 2days, 1day in between...
