iHigh Posted July 14, 2019 Share Posted July 14, 2019 i am also running 2 x 1200w LEDs and experiencing the same issue - very slight upward curl of outer edges of only some leaves Quote Link to comment Share on other sites More sharing options...

They've got a lot of basic info that's very useful but some info is misleading and doesn't always apply. Sometimes growers, myself included, have taken growweedeasy as gospel just cause they're first result on google. Being #1 on google doesn't mean it's the right answer. Read further, read forums, that's where the first hand info is. There are other factors at play here. Not just the tips are yellow. The one fan leaf a few nodes down is receding on the edges as well. @Oolong83 have you seen any further deterioration since moving the light further up? No not on these ladies Quote Link to comment Share on other sites More sharing options...

Smelly Joe Posted July 15, 2019 Share Posted July 15, 2019 Holy Shit this topic just got so technical all of a sudden. That is THE reason I don't go with hydro, ec and all that stuff. I'll just stick to my Organic ways and keep reading on this and keep wondering..... But if my 2c made any change ()......

Despite being labeled “1200 watts,” that’s the output equivalent wattage. Your BestVa will only draw 240 watts from your outlet. Instead, the Bestva DC 1200W helps you save a lot while raising your marijuana indoors. Spectrum – Is it Suitable for My Marijuana Plants? The Bestva DC 1200W LED Grow light is equipped with 120 LEDs at 10 watts each. These dual chips LEDs generate more intense light than single chip LEDs. This dual chip diode also helps in reducing excessive power consumption. Even though they’re 10 watts, they’re actually more efficient due to their increased brightness. I just copy pasted product review If output 1200w your amperage needs to be lifted to 5.45A. Your unit is only pulling 2.1A. LEDs are driven at 25% efficiency to get them to last 50000 hours plus. I have never found an led unit being driven higher than 30%, so I really doubt your output. The image above clearly states a 240w draw. The light itself is not an electricity generator and can't add 1000w on it's own to get to 1.2kw. Further, if your light is running on our 220V circuits then the units actual draw is not 240w but rather about 480w actual draw. (P=U x I) -- (U)220v x (I)2.178A = (P)479.16w It may seem confusing but that's just how the marketing around LEDs evolved, and with the given specs I can't find a single calculation that matches a 1.2kw draw/output.

PsyCLown Posted July 15, 2019 Share Posted July 15, 2019 Geez, 1200W lights which are actually 240W. Massive difference. I don't run my QB's at max, although way higher than 25%. Running mine around 75% Quote Link to comment Share on other sites More sharing options...

Conservation of energy You can't magically create 1200w out of 240/480 watts. So there is no chance its equivalent.

SkunkPharm Posted July 15, 2019 Share Posted July 15, 2019 This is not a bad light. Check on autoflower.net. they grow some nice bud with these type of lights. But when you compare it to other lights you must consider the real pull from the plug. Thus if you work out your gram per watt then you must divide your grams by 240 and not 1200. And don't expect to get the same yield as a 1000w gavita. Expect the same as a 250w HPS.Sent from my VTR-L09 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
iHigh Posted July 15, 2019 Share Posted July 15, 2019 LED's are much more efficient than any other light on the market, except LPS, so a LED that has only a 250w draw, would be equivalent to something much higher than an equivalent HPS pullling the same draw .. 1 Quote Link to comment Share on other sites More sharing options...

Yes and no. Many factors to consider as GK said it's about the conservation of energy. If I have a 250w driver and I drive a 250w QB, those LEDs are running at 100% and very hot. So hot that you can say most of the energy has degraded to heat. If I take that same driver and drive 4 x 250w QBs, much less energy is lost to heat, and a comparable light intensity from the one QB is spread over 4 times the space.

Oolong83 Posted July 19, 2019 Author Share Posted July 19, 2019 Has anyone tried the lux app in the app store? Is it accurate enough to use? Downloaded it, works and all, just not sure how accurate it is. Quote Link to comment Share on other sites More sharing options...
PsyCLown Posted July 19, 2019 Share Posted July 19, 2019 I honestly don't know how accurate the sensors are. Just checked my light and this is what I got.Max was right up to the light and had an a ersge of just over 50k around my canopy.The app I'm sure is fine, it's the sensors in our phones which I'm unsure of in terms of accuracy.

Oolong83 Posted July 29, 2019 Author Share Posted July 29, 2019 Sorry for the late reply. Tested the runoff PPM, "Fuck me" it was over 4k, so i started giving only water ph 6.3 about 3-4lt per day for the past 2 days. will water again later today and take reading again.
