Light power

quality = genetics, not the light under common sense contexts.. unless you specifically reference density of the buds. less light will result in larfier buds, and at some point that will greatly impact quality, of course, but no one should be growing weed in that context because it is easily avoided. 100g - 150g us a reasonable expectation of non-larfy buds from "100w". Efficacy of the light will be the primary factor here along with how well you fill the space. anything that amounts to less than low 20's DLI will be larfy... anything in low 20 DLI won't be incredibly dense, either. just as some people measure their dicks from their taint, you often hear absurd things in regard to yield. counting larf isn't the real weight, imho. it's fodder for extracts and such umol/s per m^2 = ppfd // ppfd "x" hours of use = DLI (simplified - not the a real math at end but proportional to hours of use, which is all we need to know) so, referencing a dli table, you can see over 18 hours you only need about 600 PPFD. there are 10.76 ft^2 per m^2. 600 / 10.76 = 56 umol/s per sq ft and operating 18 hours a day is near maximum for ambient co2, give or take. if you light gives off 250umol/s, it can cover 250 / 56 = just under 5 sq ft at near max DLI. You can give less and cover a larger area. density of buds will suffer at some point. this is a better way of understanding how much light you want to give relative to area of coverage. that is all proportional to hours of use. so over 12 hours for a photoperiod in flower, that same light can only cover 66% the area at the same DLI. or about 84 umol/s per sq ft -- ends up being 900PPFD or 150% (3/2 or 18/12) of what is needed over 18 hours. 250 / 84 = will equal 66% or thereabouts of the above, i'm too lazy to open calculator again. rounding errors may cause slight shift. i truncated the above value at soem point to a whole integer. you can do the same thing working backward from minium DLI too.. 22-25DLI is as low as you want to go, but i'm not recommending it. informational purposes only. if you are on metric system, even easier since you can skip the whole converting to per sq ft thing. just do ur space relative to 1m^2.

Absolutely my friend. You should check out some of my earlier grows when I used 100w viparspectra lights. I've harvested 100 plus grams off a plant under those LED'S brother and as long as the genetics check out and you give her love and attention...you'll have a decent little crop on your hands

Yes your expectations are exactly right. I just did this with a 100 watt sf 1000 on a jb jack herer auto. I have also grown a half pound dry plant with 100 watt as well. Your substrate will make the difference on how well they grow. 👍🏻🌱

Yes. It will be sufficient. Yes you can match just as quality canna as 1000W. Just all about keeping all your parameters in check

Just looked at your diary. You will do fine with that light in your space.

If its a decent light then 100w would be sufficient for a 60x60cm tent. One plant under it maybe 2. Decent budget lights like Mars hydro, Viparspectra, spider farmer would be fine. I use an xs2000 from Viparspectra, 240w LED. My space is small and i rarely go over 150w with the dimmer.

It depends on the quality of the light the kind of light and its leds or tubes used and the amount of PPFD and your plants DLI "daily light intake" If you got a vipar spectra 100w light that uses top bin led diodes then yes the quality will be top notch. You can yield near what others do as well, you have to consider a 600w light will be for 4x4 or a 5x5 area. Your 100w light will be for 2x2 roughly? So when you compare it, you have to compare it to the same size. Yes it will match the quality of the 600w but it will only be 1/4th the area. If that makes sense. I've seen large large yields that are top notch from 100w lights. My Mango smile was just harvested and was 7oz off one plant. I had it under a large light. But had 4 other plants as well. It by itself would fit in a 2x2 so you definitely can get a half pound out of a 2x2 with a 100w light and quality comes from the genetics, nutes used and Regarding the light the spectrum of light the light pushes out.. which comes from the diodes used and or tunes. Short answer yes you can, but no you can't cover the same sq ft area as a 5-600w light. Please consider me as the answer so I can be entered for a chance to win grower of the month contest I would truly appreciate it ❤️ 😊
