growdiaries.com/diaries/158199-grow-journal-by-ziooomoooleeek Co powoduje że liście wyciągają się w stronę światła? Czy to normalne czy powinienem się martwić? Dziś podlane. Lampa LED 40cm od górnego szczytu. Temperatura 24c - 25c wilgotność 55%

i should inquire about how you are adding co2... if it's not regulated to 1200-1500ppm, it's probably not an effective method.. like "co2 bags" or "exhale bags" you need something around 30-40lbs of sugar to provide enough co2 over 12-14 weeks for a small room/tent.

you can probably provide more light if they are praying that hard. reduce height or increase power.. changing height impacts evenness of coverage, so weigh your options wisely. CO2.. if you are adding CO, you are in real danger. ;P at 25c and 1200-1500ppm you can push 50-60 DLI if other factors are well-controlled. So, you have 3x TS1000 ... gotta give props to mars. I give a lot of light companies shit bc they lie their asses off on the mid and lower range lights. This looks to be accurately measured. It's not promising anythign crazy on efficacy relative to price range and diode count of the unit. 343 umol/s * 3 = 1029 umol/s provided .. though you actually give a bit less than this - some miss plant, some is absorbed by walls etc... Need to know size of room to calculate PPFD and DLI. Make sure to use the "20 hours a day" row of table (or possibly column, doesn't matter which it is) PPFD = 1029 umol/s / area in meters squared. So, if 4x2.. that's 8sq ft / (10.764 ft^2/1m^2) = .743 m^2 ..... 1029 / .743 = 1384 PPFD over 20 hours is a whopping 99.6 DLI.. so, definitely don't give more if this is the size of your space... let's assume it's a 4x4, then.... 1029 / 1.49 m^2 = 690PPFD over 20 hours is ... 49.7 DLI and you could probably increase the light you are providing to that size of an area (4x4) by 10-20% ... Distance from canopy affects light intensity based on inverse square law. Halve the distance and it is 4x stronger. So, it doesn't take much to increase by 10-20% via this method... if you can use a dimmer to increase power, this is usually better option as evenness of coverage is dictated by height from canopy too. Weight your options. local environmental variables will dictate how much you can push it. Temps/ RH / irrigation habits etc... only if on point will you approach 60dli without light damage. So, you see the math above take 1029 and divide by m^2 of your coverage... Google a DLI table (daily light integral) and reference that resulting PPFD value and hours of light per day (row x column) and this will give your DLI... regardless of size of garden, DLI means the same thing per day. 65DLI is theoretical limit of photosynthesis based on biology of what is going on in the plant. You likely will not get that high without causing damage.. so start somewhere safe and beef up slowly.. it sometimes takes more than a few days to see the damage caused by 'slightly' too much light... they may be fine intiially but eventually will be all droopy as fuck toward end of day. Oh, hours per day is also a good option to adjust DLI. it is proportional.. take off 10% of time, and you reduce DLI 10%. same wtih adding 10% time... though some amount of dark period is likely beneficial. again, this one and the dimer options are probably your go-to first choice to make fine adjustments based on how the plant reacts... Praying is great.. excessive praying can mean it's trying to reach more light.. if any vege growth remains, it'll stretch, but if vege growth has stopped, it's difficult to know just be looking... running the numbers above for your area will make it obvious. Ambient co2 can hand 40-ish DLI.... even that may be slightly too much in some circumstances. Added CO2 can go higher... 25C at leaf is what you want... 1.3-1.5 VPD (refer to a vaper pressure deficit table) will mean your environment is on par to provide a healthy rate of nutes for growth. more frequent, smaller irrigations will generally outperform longer interim periods and larger volumes of water per pot. But, that needs to have the proper drainage qualities and most likely soilless.. this will match hydro rates of growth within reason.
