I moved the ufo up about 6 more inches hopefully that will stop the twisting. Any advice is welcomed.
Hi Auto. yeah your right about moving the light up a bit to stop the twisting, i have mine about 12 inches above my Auto and will keep it there until the 5 week or so, then ill move it down to 6 inches, i got a 270W unit in one grow and a 240W in a other.
Both in cabinets, as far as the twisting goes tho it wont harm your plant it will jusst look a little weird.
The closest ive had my 270W ones is 1 inch away and they bleached the buds white.
Twisting could have something to do with the LED light bouncing around all over the place and the leaves are just trying to turn towards the best light source.
Anyhoo, they are looking good mate.
90W ufos have come a bloody long way now and they too are providing good results for the wattage.
AS far as the blending of the lights into green, again, the plant is spectrum sensitive so it will filter out what it needs and doesnt need from both the yellow and blue but will indeed ignore green. But as the two spectrum are lightly mixed the plant will still know what blue is and what the yellow is.
Its all about the NM's of the colours mate, ie red at 660Nm Blue at 425 Nm, plus the LED will still direct the light towards the plant, so what you are seeing basically, the greenish hue, isnt what the plant sees direcly underneath the light, if you were too look directly up at the light from underneath you wold see what i mean but i dont recommend that, just point a camera upwards at it and have a look then.
Heres an example;
From the Side - all pinkish whitish light,

Now from directly (sort of) underneath with my camera at its lowest light setting,

You can now see the seperate coloured LED's
Also depends on what angle your UFO lenses are at 60, 90, or 120 degree
If your getting a lot of light escaping the sides then its probably a 120.
You could make some sort of reflector yourself to go around the UFO to direct the light more downwards, ie more like a 60 or 90 degree.
Its all fiff faff tho, like i said before the plant will know that the two lights mixing into green are still two seperate lights.
Does that make sense? just had a Tangerine Dreamy Big one.......so sorry if rambling ..... lol..

Hope that info helps mate.
