LED Question

I recently purchased two HLG 100 Rspec's to play with. What is the best way to incorporate them into what I have ? I currently am running a 5 x 5 tent with 1 1000 watt HPS in a 6" Raptor cool hood. Can I just hang them parallel with the tent walls for more penetration from the side? or would it be better to hang them say at a 45 from above with the HPS in the center.


How would you do it?

Two hundred watts of LED offers up a wider range of the light spectrum and should add nicely to the HPS. I would hang them at a 45 and just below the 1000watter. This would add most of the extra light directly to the top colas, where it will pay off the most, while also adding some more penetration lower down. You should see a nice increase in yield.:goodluck:

That should work great. It looks as though you have rigged them independent of the 1000watter. The led's can be hung much closer then the hps. Your garden will be lovin it.:goodluck:

Im with blue, drop those LED's down.
 
I just started my grow, using two Lights 1600W Phlizon LED (actual wattage 335W)and a 600W Phlizon LED (actual wattage 100W) in a 4X4, doing one big plant this time around! Here’s a pic of my set up, similar and pic of some buds from my last grow under “zons” lights lol Good luck with your grow, I’m in for a watch!

The girls seem to like the LED's...so I added two more. Is this overkill? or is there such a thing. here is what I have now: 1000W Hort super HPS surrounded by 4 HLG 100 R-spec's each one pulling 95 actual watts in a 5 X 5 tent. These girls are 3 gold leaf, one skunk in the back and 2 WW on the left. The 3 gold leaf and skunk are in WK 6 and the 2 WW are in WK 3. I had to drop the photo period to get the gold leaf "auto's" to flower....again. At this point, I am thinking they grabbed my gold leaf seeds from the wrong bin.... 5 of 6 did not auto (1 did not sprout). No matter, still turned out well last time. I don't know now at this point if I want to ditch the MH/HPS setup and go with all led's eventually, or stay with a mix, what do you think? Oh...and two Ca light works UVB's.

That's a lot of power for a 5x5. 600 watts of HPS alone would do the trick. I personally would ditch the HPS & go all LED since you have plenty for a 5x5 now. 1 light over each plant would do an excellent job.

Optimum is 40-50 watts per sq ft. So having 25 sq ft you're good. I'd get a lux meter to make sure your lights are at the correct height, and you don't burn/bleach your plants.

Have one....have the lights set for about 85-90k in the center around 75 on the sides...will have to measure again, but that was about 20- 24" above the canopy.... that was before the last two additions. If I remember right, I had read that around 85K was max.

You think so?, even once they get larger? I would think that penetration and the sides would suffer.

I'm guessing that each light has a 2'x2' footprint + the UVB's you have should do just fine. If I was to keep using the HPS too I'd turn it down to 50% or 75%. They claim the 600 watt HPS are the most efficient. I use to use HPS combined with Mars Hydro LED's. Then went straight Mars & didn't notice any real difference in weight per plant & my buds were more compact. I've since switched to Bar lights & run a 10 Bar 800 watt Phlizon in mt 4x8 tent & a Mars FC-E3000 4 Bar in my 3x3 tent.
 
Yes 2x2 flower. I have thought about dropping to a 600.....Now, I can not run a 1K bulb at 600 watts, I need to get a 600 bulb.......right?

I moved the skunk out to another location and put one of the Rspec's above her......will see how she finishes out.

Checked my Lux readings about 22" from the main canopy I have 85K in the center, 70ish on the sides. I have one plant taller than the rest at 15", and it is 130K at the top. Nowhere does it drop below 45K.

You're gonna fry your plants at that lux. Max 50k lux. And I still bleached out my plants. Turned it down to 40-42k and all is well.
 
OK.....after some research, I think you guys are right. I am pretty sure at this point that the waxy look to the tallest plant and a little strange shape to the leaves is called light stress (lol). I am not sure now what to do. I have turned off all the LED's and still have 50-60k at the canopy, and over 100k at the top of the one tall plant and can't raise the light any higher. I at at the beginning of week 8. I think maybe I will order a 600 watt HPS bulb, turn my ballast down and see where I am at from there, and add back led's as I can, or should I ditch the HPS all together....



Hmmm.....
