**ULTIMATE LED TEST** *GLH Spectra 290* VS *Blackstar 500* VS *Hydro Grow LED 336X*

Try it out man. It may not be that though according to wejuana he made a lil boo bio recently with nutrients possibly slowing growth a bit. But again it's also possible the out the green too. Cannawizard is running some green spectrum bulbs u may wanna consult with him as to the proper nm of green to throw in there because I know some greens won't do anything for plant growth. But I don't know enough about all that to start guessing at it.

Buds are getting fatter! Hope you can get the leaves looking better, looks to have some issues there with the browning leaves and curled tips. I like what im seeing from all three panels though in terms of bud development. So far the panels are performing as I expected. Seeing the 1w penetrator performing like it is makes me wonder about the 3w version. WeJuana, you truly are inspiring me and making me want to test more panels myself!

Still looking pretty solid, keep up the good work.

Thanks man for the info, I may be wrong but I think the green peak should also coincide with cartenoids, just spoke to an old friend in England who is a plant biologist and he agrees with this train of thought on the nm range . Peace bro

anybody growing with Haight Solid State LEDS on here? are those 6W diodes good to grow marijuana?? thanks

I know I asked a while back I just thought there was new comers on here.. there is not much on the net about them ... I am thinking of trying the 90W they have...

Here's a link to some journals have look let me know what you think... Endur0xX

https://www.rollitup.org/advanced-marijuana-cultivation/216015-haight-solid-state-led-grow.html

some of those threads are using the same light I am planning to order but those threads started back in 2009... with 6W leds in 2009? how come they are still the only company making 6W leds if the 6W diodes have been around since 2009!?

As my understanding of LED's goes, the higher the wattage of the LED the less efficient it becomes.

Using 1 watt LED's gives a higher reading on a lux/par meter than the equal wattage draw of 3 watt LED's, but 3 watt LED's provide better penetration into the canopy than 1 watt.

I read that somewhere.... I'll see if I can find the source...

Read that too, but from having played with 1, 2, and 3w units am convinced that the 3w chips are worth the $$. As for the 5 and 6w, we'll have to wait and see but I would suspect that unless they are driven through a very wide viewing angle (120 degrees at a minimum) they would almost be too intense. I have to keep my 3w panels at least 8 inches, probably more like 10 inches away from the canopy or my plants get bleached big time.

In my research I also read that 5 plus watt diodes are also very hard to keep cool and are subject to burn out quicker. This could be why we don't see many of them on the market ... yet.

surprisingly, they run with no fans.. I am pretty sure they are really wide angle, cant find it on their website right now though. As for the distance from the canopy, on their website it says : The PPF-400 should be positioned approximately 6-12 inches above the canopy. Closer than 6 inches can result in stunted growth during the vegetative stage but it is a good idea to move the lights closer (2-3 inches) during flowering

there is no mention of bleaching! I think that having a mixture of 1W, 3W and 6W LEDs might be a good idea. !

The reason no ones using em is they just aren't efficient for those of u just Colin into he led game LEDs started to step up their game big about 3 years ago or 3.5 years ago or so. Lots of new company's with "revolutionary" designs. Many different style chip sets and combos and different wattage diodes. Basically anything over 3w loses so much efficiency to $ that it's not worth running them. Also u run into the issue of like hoss said too much juice over ur plants eachjng and also massive spotiness in ur spectrum mix because of less LEDs per square inch. Basically it's been found that 1w was the most efficient but then u have cooling issues and also cost because of the sheer amount of LEDs used. What needed to happen has a balance of lower to number of LEDs enter 2w and 3w chipsets. These are ideal and it's What all major led company's that are doing anything of note are using. Haight has basically been debunked IMO but that's my opinion and u can draw ur own but I personally will not buy it unless it uses 2 and 3 watt chipsets

Blackdog makes a 5w panel. I would love to put it to the test. Also comes with a lifetime warranty, something else I haven't seen being offered.

Indeed a lifetime warranty hmmm that in and of itself may be worth it lol

I'm sure the lifetime warranty is about as good as the warranty a used car salesman will try to sell you.

Right full of a million loopholes I was about to say he same thing right now I'd have to go over that with a fine toothed comb first lOl

damn that is a serious light though I would love to see a journal with someone using one anyone know of any?

Warranty is only as good as the retailer, as most of us dont buy from manufacturer nor is it stamped on my lites who or where it came from, the warranty only exists as long as GLH is doing business as GLH for example...

yeah that was kinda my thinking there is no way that company could be replacing thousands of light a year for free forever (or however many lights a year who cares that's just my example)

Maybe reading would help lol I as I said before I bet it's full of holes for the to jump through to get out of it
