@maxpesh - Light movers are definitely the way to go to increase footprint with LED! I'll have to look into those, I didnt know they carred em (:
@Endur0 - Im planning to leave the PPM4 on and let it do its thing during both day and night when I get it to see how long a bottle of CO2 lasts, and then I will adjust accordingly if necessary and if it seems like its getting used quickly.
@KawiZZR - I apologize for that! It seems like she sent me the wrong chart! That chart is for the 336X-Pro, I am using the regular 336X. I just glanced at the stats so I didn't realize it was for the different model until you pointed it out. Ill see if I cant get the correct chart and post it. Sorry again for not checking the info more thoroughly before I posted it!

Noticed that in Cammie's fancy chart she claims the light draws 500w, but when you tested the unit it was 334w. Was this addressed this when she contacted you? I could see people being pretty pissed if they bought a light that claimed to pull 500w but only pulled around 2/3 of that. At least with Blackstar everyone knows that the light only draws 2/3 the advertised wattage and their price reflects that.

You'll notice the chart says that data is for the 3w version. Wejuana has the 1w version which draws around 300w...claims are consistent with what is being advertised on their website.

looking good....the blackstar seems to be slightly ahead, but that doesnt mean much right now......great job

Thanks! Yeah at this point the Blackstar plant has more developed looking bud sites, but as you said, at this point it doesn't mean too much.

do you think the LEDs make the plants grow with red stems? as if they were stress or something? or it's just the light making it look like that?

To be honest I am not too sure. In my past LA Con grows, I saw red striping throughout the grow on the stems which led me to believe it might be part genetics or even a pheno.


I noticed during the last grow that the healthy fan leaves all had a nice light reddish tinge to the stem when then seemed to be in-taking energy to the plant, and green when there was new growth such as the bottom of stem when rooting or new leaves.


The red is definitely different than the stressed red, as seen on one of the Mag deficient plants.
(GLH's whiter hue shows the deficiency easier than the other LEDs)

leds dont change stem color its genetic, it just really pops in pics cause of color spectrum, theres one thing LED's amaze me for more than anything else, and even if i end up goin plasma someday ill always have an LED panel on hand to diagnose bug and deficiencies as they show up like MAD under the LED coloring, unless your leaves are black under the lights for example your not feedin enough N. You can see spider mite dots like you can see white powder flyin through the air under a black light, fuckin AMAZING how defs and damage shows up under these lights.

lookin good glad to see some action startin up in here on the strength now.

Okay that makes a lot more sense, thanks for clearing that up guys. WeJuana, considering the penetrator you're using has 1w and the others are 3w, how do you see this playing a role later on in the grow? Also, with the differences in lens angles, can you tell by looking at the lights how each footprint is different regarding intensity within the core coverage area and the rest of the tent?

Visually I can't really distinguish if the difference in intensities or foot print is due to lenses, wattage, bulbs, size of unit (the Penetrator 336X is about 2 times as big as the Blackstar/GLH, which are basically the same size). They all seem like they can all handle a 4x4 tent though.

Just wanted to let you guys know the www.growledhydro.com website is going to be completely redone. A lot of the information on there no longer applies to the new models. It should be updated in the next 3 weeks. The lights sold prior to this test were sold as actual watts, so if you paid for a 500w light you got light with true power draw of 500 watts. The new panels being sold by Spectra LED are powered much lower The panel you see in this test is basically the 500w panel just powered at 450mA pulling 360w, both panels use 252 led's which is what you pay for not the wattage drawn. Ill update you guys when the new site is up.

Its kinda funny when everyone was hatin on blackstars because they were only drawing about 60% of the wattage labled but maybe they were just ahead of the game a bit and we didn't know it. There's lots of advantages when you don't max out the led diodes.

what led light would be a good starter light, that would replace a 2 foot 8 lamp t5, work good in a dr80 31"x31" and still give u ability to flower?

LA Con clones are only days away from getting potted.
Vegging for 2 weeks and then into the flower tents!

Any opinions on which strain to clone next: "Trinity Kush" or "Power Africa?"

Have you seen this thread? Might be a good option for you if you've already got a T5 fixture.

If you want an LED panel, and if by "starter light" you mean something inexpensive but effective, this one is a good option, by all accounts. If you have a little more to spend you could go up to their 500w model.

I would recommend the 240w Blackstar High Output if you are looking for something priced for someone entry level that can go seed/clone through flower for a 31"x31" area.
Personally I think a Blackstar 500w may be a little much for an area that size.. but again that's merely my opinion.
