240 Watts All White LED Grow Northern Lights

[trueg115]

First pick of the crop. Still not fully complete yet, going to let them go a few more weeks, there is still new growth coming in and more resin developing.

 

[hyroot]

Wow Im impressed with the all whites despite other issues. I wonder if adding a couple red 630 and / or 660 would make a difference or not.

 

[trueg115]

I wonder what it'd be like without issues as well.

They are each set at 90 degress, enough to get good penetration yet spread the lights out for a mix of color.

So how was the penetration using 90 deg lens? And how close can you get the plant without bleaching? I'm seriously considering speccing an Apollo light.

Thanks!

 

[trueg115]

I could get my plants anywhere without touching them without leaching. Once they touched, they leached and browned. So penetration was good, but remember this is only white. I didnt get to see too much penetration as time went on since it was pretty crowded the whole grow but quite a bit of the plant is receiving light.

I would suggest you to add one or two NW instead of so many 6500k

I'm looking for a flower only lamp, so going to focus mostly on 2700k-3000k for my LEDs, but will try to balance it out and get it close to 10% blue.

 

[hyroot]

theres enough blue in the warm whites and neutral whites,

 

[brotherjericho]

What benefit would neutral give me over focusing on just warm for a bloom light? Seems it would up the green a bit. I was considering mostly WW and some 630nm or 660nm (if they are available).

 

[trueg115]

It has been shown that blue light during flowering is beneficial to the plant so it helps growth overall. There are still processes used in flowering that use blue light, just at a much smaller amount then red and orange light during flowering. As hyroot said, WW and NW will supply plenty of blue. I personally used so much cool light because I wanted to veg as well with it

Calyx's swelling noticeably now trueg, only days away by the look of things

 

[trueg115]

That is plant # 2, of which is predominately Indica, so i am actually cutting it tonight. In need of medicine and there is plenty more colas on the other two plants to do so. I only have 4 weeks left until the move anyways and want to get the rest of the plants with as much light coverage as possible.

 

[trueg115]

Let the pictures begin! Note: this plant has a small yield due to me picking medicine off her from about week 3.

 

[hyroot]

I like the close up pics. That looks bomb. The one with the bird cage looks like lettuce and guacomole. Lol I know its the camera. My camera sucks too. Mine wont even zoom in or out.Try putting it to black or dark background when you take a pic. It really makes it pop. If you have seen nugbuckets pro photography studio set up for his plants.

 

[trueg115]

It is smelling bomb as well! I will take that into consideration though next time, I was trying to use the bird as a size reference.

only about a week or so until the next harvest!

 

[trueg115]

It starts getting good and everyone dissapears haha

Maybe the white haters can't bring themselves to believe awesome buds can be grown under white only leds

I know I get my share of doubters

 

[brotherjericho]

I don't know that there are white haters, just many who don't see the point. If I want a mix of WW, CW, NW, etc. I can do that with fluorescent already, and at a much lower price up front. What do you believe LED whites have to offer that can't be accomplished with regular 3000k, 5000k, and 6500k fluouro t5 or PLL?

those flourescent are not the same as led in spectrum not even close. they are tri phosphor. only having 3 spikes 1 blue, 1 red, and 1 green all in the wrong places. they are not full spectrum at all. kelvin is no way to be measuring spectrum. its based on black body radiator temperature scale.


this is a typical 6500 k t5



this is a 6000k from cidly'



see the difference. t5 kelvin bulbs doesn't cover shit where led does

here is an aquarium t5 spectrum not kelvin rated. flora sun

the better the spectrum and more red they have the less they last. they start degrading after 6 months . they last 8 months to 1 year. so led in the long run is cheaper.

Not if they are built into a fixture that is not user friendly to replace the 660s. Advantage LED tubes, Agro makes a 660 $71
