Upgrading light again the sequel :D

[Rey]

Now the I am done with the winter side, I upgraded the summer side corner..The light weighs about 33lbs thank god it came with a pulley . About 1200watts for two floors.

Spec and timing..
.
Summer corner: (70F-80F range)
-2x Amare se500(daylight w/UVB) @ 515Watts ea.
-2x Red only G8LED @ 90Watts ea. (sunrise/sunset)
.
Winter corner: (50F-60F temperature with window cracked open)
-Top floor: 5x T5HO @ 200Watts total
-Middle floor: 2x Optic LED 2, 1x T5HO UVB, 2x red/blue strip (700Watts total)
-Bottom floor: 3x red/blue LED strip, 2x T5HO, 1x T5HO UVB (360Watts total)
.
.
Timing:
Summer corner: The red sunrise/sunset will turn on 6am to 9am, then 4pm to 7pm. The daylight will turn on 9am to 5pm.
.
Winter corner:
top floor: 3x 3000Kelvin will turn on first,same as summer corner.
Middle floor: 2x red/blue first, same as summer corner.
Bottom floor: 3x red/blue first, same as summer corner.
The rest will turn on 9am to 5pm for daylight.

Comparing PAR light output both inside and outside sun..
11:15am ET = 1283 umols (Outside)
1529 umols at 18” distance (Grow light)

@Rey you really know your indoor plant lighting; I'm going to have to come to you for advice since I've only started to learn about PAR and the different wavelengths. This reminds me, and I have it someplace on a piece of paper on this desk, but I have to take a closer look at that PAR meter you recommended.

 

[Rey]

yes, it is very important to know the range of the quantum meter on which it measures the PAR. I think mine is 400-700nm, anything below that is UV and above is infrared which is not added to the PAR measurement.

350-750nm is what I see as visible spectrum from various sources at work. Not that it matters with frequency roll off and shifts. What is the difference for cool season and warm season plants please?
