I agree! But you could have used x2 100-150W lights instead of x2 360W? lights... loltheres no way to distribute an even 800 uMoles over a 2x4 canopy with a single light
Should be interesting though!

Nice man, and I'm not criticizing either!I only got two 400W because I got them bot at 50% as part of the feedback program so I jumped on the chance!
I would otherwise have gotten 2x 200W SS instead.
Thinking ahead is all
Plus I'm hoping to stress test the cooling system and see how it fares.
hmm... knew that sounded a bit familiar, found that from your last version of this journal, along with some reading recommendations that were worth your while."Now the book says plants use plenty of the blue spectrum and red. So why are modern LED white and red? What happened to the blue?"
They have found that too narrow of blue wavelengths had caused the notorious LED bleaching *gasp* either from the light's height, or the diodes lens. I think it was specifically 420-430nm that was trouble?
The White LED's..
-Cool White 5000-6500k
-Neutral White 4000-5000k
-Warm White 2700-4000k
..cover a much wider spectrum than most if not all led's- including that blue wavelength that was causing the bleaching. So many ppl have slowly converted to running a majority of variety of White's, and then filling in the gaps with the specific wavelengths they need/want to revamp. (430, 460, 630, 660, etc)
Sounds like it's working out pretty well too, been looking at DIY'ing a few panels in the future.
Now that I remember where that 420nm info came from, you folks better not take it too seriouslyhmm... knew that sounded a bit familiar, found that from your last version of this journal, along with some reading recommendations that were worth your while.
Kali Mist is 90% Sativa according to the Serious Seed website, so even with two SS400W I'm at 80w/sq ftEquatorial sativas need intense light and do best with between 70-80 watts per square foot (w/sq ft) (750-860 watts per square meter (w/sq m)). With less light the buds will be loose and lanky.
This may help too:INDOORS
Plants in indoor gardens require very bright light to grow well and yield a good crop. However, varieties differ in the amount of light they require to support fast growth and high performance flower development.
Sativas require the most light, followed by sativa-indica hybrids, indica-sativa hybrids, then indicas. Sativas require the most light. They evolved below the 30th parallel, near the equator, and are adapted to long periods of intense sun.
Sativa-indica hybrids need less intense light than sativas, but still do best with light on the high range. Indica-sativa hybrids are more lightforgiving than sativa-based plants. They can function in the mid-to-low light range. Indicas need the least intense light of any of the varieties. They evolved in northern latitudes and are the best bet for low-light gardens.
During the growth cycle, most varieties will do well with 2000-2500 fc, (21,500-27,000 lux, 400-500 μmol/sq m/s) although the plants can efficiently use 5000fc (54,000 lux, 1000 μmol/sq m/s) or more. The more light they receive during vegetative growth, the faster their growth and the sturdier their stems. When grown under low light, or under a leafy canopy or when shaded by trees or other tall plants, all varieties develop long internodes (spaces on the stem between the leaves) due to the enhanced far-red light; plants with equatorial genetics are more affected by this.
Equatorial sativas need intense light and do best with between 70-80 watts per square foot (w/sq ft) (750-860 watts per square meter (w/sq m)). With less light the buds will be loose and lanky.
Sativa-indica hybrids require bright light. They will produce luscious buds when illuminated with as little as 60 w/sq ft (640 w/sq m).
Indica-sativa hybrids require less light and can produce very good buds using about 50-60 w/sq ft (535-640 w/sq m).
Indicas need the least amount of light to thrive. Some indicas produce well starting at about 40 w/sq ft (430 w/sq m), though others need 50 w/sq ft (535 w/sq m) to produce nice, tight buds. More light, 60 w/sq ft (640 w/sq m) doesn’t hurt; at 60 w/sq ft (60 w/sq m), the buds will be larger, tighter, and more potent.
Gardeners have a wide selection of lights to choose from. These include fluorescents, metal halides lamps, high-pressure sodium lamps, and LEDs. Cultivators rarely use incandescent or quartz halogen lights. These lamps are inefficient, converting only about 10%–20% of the energy they use to light and wasting the rest creating heat. If you are planning to use an incandescent lamp to light a “dark spot,” don’t. Use a compact fluorescent or LED instead.
