Mix 2 65W hans panel with an 600W hps ??

Hello all :)

Actually, got 2 hps 600W running in a box L 1.50m - Wide 80cm - tall 2m

with a mobil climatisation which blow cool air in front of the box , ( the box is open so ) , temp is above 28-30° .

Due to high temp just outdoor ( more than 35° ) i would like to remove one hps ,
and put the 2 hans i got instead of
1 Hps will be in the middle of da box , 1 panel to the right and other to the left .

My question is , does it useless to do this , becuz of the extrem difference between the power of both lamps.

I dunno how the "lights" works , but maybe the hans' light will be "swallow" by the HPS power .
U know , like if we are putting 2 candels near a 500w spot to make more lights ..

Dunno if it clears , but do you know what i mean

Thx for help :)

Yeah that would be dope, and it will help hit random light spectrums you are missing out on, get a little more resin, I think you should go for it!

ok , thanx man ,
i change the setup , and put like i said hps in middle and panel on left and right.
The temp is better now but always with the clim
I just hope , i 'll dont have kind of umbrage zone due to the panel's tilt ( or angle ) on the side and the hps in the middle
( hps is at 60cm from the canopy and panel at 15 )

Well 2 65s ain't gonna replace a 600 IMO but with your footprint they should help keep the ladies happy. If you want another opinion do yourself a favor and have some fans blowing on those Hans panels. Their output tends to weaken as grow room temps increase, the Hans cooling design is rudimentary though the 65 may suffer less than the other models since it was the original production design and doesn't draw as much as most of the later panels. Now if you're angling the panel you've changed it's cooling profile a bit so now all the LEDs on the panel aren't working effectively, at least that's been my experience with my Hans panels and bad temps, so adding some cooling to them would be a good idea IMO since you're going to want every ounce of performance out of them to try and replace a 600.

Have you looked into building a DIY COB rig? They are an great choice for growers with heat issues since you can run them at very efficient levels and you can also add dimmers, which are very useful on extremely hot days or when going on vacation. Price might be an issue since you'll need more COBs to cover your grow area the more efficient you run them and you'll want quality dimmable power supplies but if you're growing for profit then they will pay for themselves quick enough. There are a few companies making COB rigs but then that's even more expensive and doesn't give you the ability of building the lights to your specific grow area, one of the strengths of LEDs.

Good Luck!

Edit: Why do I keep thinking you're running 65watters??????

Alright with cooling the hans , when flower position on , the panel are getting hot , i know the led are less efficient.
But its just by the top of panel , not towards plants , which is not bad .
And yes , fans blowing the panels and the temp decline pretty easily.

Yes , i was thinking by DIY cob , have some nice help from Supra and others user , i just dont get the money.
i would prefer cxa 3590 at 72V but so hard to an driver to run them , and not too expansive
so next lamp , will be DIY, with vero 29 cob .
For compgny i was on this one http://www.spectradesignlab.com/spectra-cob91.html , but i think they are dead .
i have contacted them in december 2014 , the guy told me that the spectra 9 cob , will be ready in january 2015 , and nothing yet , so ....
But yeah , this solution are a lot expensive compared to DIY we can make ( the cob 4 is about 500$ )

Sorry but dont understand this one :

Now if you're angling the panel you've changed it's cooling profile

By angle i mean panel are not upright, i inclined them , and i read , some wavelenght may vanishes and it created umbrage zone ??????
Well , nothing to have with the cool temp , btw

In fact , i would like to know how the light do , when u mix diffrenent kind of lamp at different power

Why do I keep thinking you're running 65watters??????

i'm running 600W hps , and the two 65W hans but i think u get it :)

Well , thx for help dude :)

Maybe they have something in the pipe for you though I'm a big fan of strip lights outlining a grow area.

Umbrage? As in shade effect? Yes they will stretch plants if the output is too low for the plant or area. Is that what you mean?

Yes angling a Hans panel will kill the output of the upper diodes since it was designed to be used horizontal so over-loading the "heatsink" isn't wise but if you can keep it cool or add some extra heatsinks to the upper part which should help pull heat away from the LEDs you should be okay IMO. Hans panels have pretty wide beam angles so tilting them too much can be a waste of light. How much are you angling them? Funny part is that when you tilt them the output from the upper part of the LED is more intense, a bit more concentrated, than the lower part which becomes a bit diffuse so in some cases you may want the output of the upper part to be a bit less intense.

Which brings us to mixing light sources and from what I learned it's best to have the ability to move the panels and/or plants around the grow area until you find the plant's sweet spot. Multi light sources that aren't really well thought out can be a pain in the ass since some strains will like a certain moles/day and others less so, so they or the lights will need to be moved until you're familiar with what the strain likes, as in what amount and quality (nm) of light it prefers. In other words it's pretty easy to stress a plant out growing with different sources and dumping CalMag into the plant isn't going to help. Having said that when you get it right you can produce some pretty damn dense colas.

thanx for all this precision ;)

Yeah i was meaning shadow zone !! ( i knew the word for umbrage , impossible to remember it lol )

for now , i cant cool more the hans panel , so ...

I'm angling the panel , i think from 30 degres maybe , i 'll take a picture , tonight , will be better than words .

Hi , cant take picture for now ,
temp outside is so high ( 35° ) , even with the clim, i'm on 29° , excpet where the blow's clim is diriged ...
But anyway , got no choice for now ... thx for helping dude :)
