Bonus Seed: Gelato Auto - FastBuds

You're in pre flower stage. DLI and that. You need a good lux meter. And knowledge. And if you're asking this. Then you really don't need to be getting into it Until u understand 101s. How to bring a plant through different stages. DLI and fine running will come. Shit im still fine tunning 3yrs in. Different phenos require different stuff. With that being a full gal. 16-17 hrs of light. 5-700 ppfd (keep 45 distance) as you're still in a growing phase. So, you want it to keep progressing. When the stretch (pre flower) has stopped u can give 1000ppfd canopy wide. Move to 30cm and push through with sugars and good pk boosters for heavy flowering. Don't let the soil substrate dry up in pre flower. Don't defol. Feel free 2dm me if u want expansion on what's said. She Is looking good. So, as she comes into pre flower. Just be much more careful when feeding as it gets very sensitive at that stage. Good luck.

Wow, they run those diodes hot at 0.8watts per diode. They are tested on samsung.com at .20 watts per diode. Unless those osram chips, only 12, are shifting the average wattage signficantly, this spec sheet is not to be trusted. EDIT: Ahh, if run at "134.44 watts" in the link you gave, which would be a better but still not what samsung tests at for the 50k hours longevity (L90) and high efficacy numbers (umol/J) to be true. 134/300 = .45 watts per diode, which is still more than 2x as high as what they are tested at. This means the efficacy and longevity will be greatly reduced and you will generate more heat per watt. Despite this, the light can still work well, but you'll want to run it at a lot lower power than 240w and it will still cost a bit more umol/s produced compared to a more efficient light and produce a bit more heat per watt used, too. they can't do the math well, so more lies are possible. "3.0umol/J" and 631umol/s do not add up. 631 / 240 = 2.62, which seems exagerrated as-is and clearly not "3.0" using their own numbers, likely bogus because running these diodes at .8watts per diode will be much lower than 2.62umol/j. The 631 number is likely wrong. Bet it's closer to 450umol/s from this light, maybe less. This is a 130-150w light. It won't last long if you run it at 240w. So maybe 300umol/s of output at sane wattage. 0.5m^2 area or so for 12 hour operation and .75m^2 area for 18h operation. Before i realized it, i did the math for 240w.. it shows more details on how you get to these numbers. running at 240w, but not recommended. With 12 hour operation you'd want to focus this light for the best coverage over .75m^2 and you'll hit a good DLI (daily light integral). With my guesstiate of 450umol/s (running at 240watts) that'd give you 600 ppfd in a .75m^2 space. Tent walls would obviously help. This light is probably clsoer to 2.2-2.3 umol/J 18 hour operation can expand that coverage by 150%, or 1.125 m^2 area. Hanging distance can be adjusted using a free app for light intensity. Even out center-to-edges as best you can without sacrificing overall average light hitting entire canopy. QBs - 18-24" is probably good. A littl emore distance with some quantum boards can really help light distribution and reflective walls will mitigate potential waste up to a point. An led frame with bars/strips of more spread out diodes can get closer, but ~18" is usually best to get some spread of light and due to dynamics of inverse square law (rate at which light spreads out). Seriously, don't run this light at 240w. I don't even think that is in the range that samsun says it's safe to run, lol. That is 4x higher than what they test them for. Maybe with active cooling? the low end lights on market are around .5watts per diode. That's 2.5x higher than samsung testing. This light is comparable to the numbers of the XS1500 by viparspectra, if you want to look at their par maps.. if this is not a qb, it'll do better with light distribution.

50 cm from top of canopy is always safe distance. Any app on mobilr will count lux or will convert to any numbers.
