re: GrowLEDHydro 300W LED vs. 400W HID Demonstration
Apparently my question was overlooked.
Your question wasn't overlooked, I just didn't have an opportunity to get to it yet.
The comparison to me seems biased, seemed more like an effort to keep them the same rather than let one get away from the other.
The only way to isolate the *lights* as the primary variable as much as possible is to provide both groups with as close to the same environment as possible.
But there's other ways to look at it. I could have, for instance, not have upgraded the HID fan to match the lower LED temp, and just allowed the HID tent to run significantly hotter, but that would compare just one aspect of performance and throw everything else off that we're interested in comparing.
My goal on this grow was to balance isolating the lights as much as possible as the main variable against optimizing each tent individually as much as possible.
It turned out to not be as difficult to balance those things as I thought it would be, because both of these lights, while of grossly different design and technology, turn out to work quite well with the same grow setup. Their intensity and coverage doesn't appear to be very different, so they worked well with the same grow parameters and height above canopy.
I'm curious as to what you would have done differently as far as optimizing each tent individually?
In any case, I respect and appreciate your viewpoint and comments, and I don't construe them as being negative.
Something else we may be losing sight of here is that I did this grow primarily for my own personal edification, not to "prove" anything to anyone else. I had searched the Internet for successfully completed LED grows for a long time, couldn't find any, and decided to find out for myself how LED lights work.
I love to grow medical marijuana, and I love to help other people grow medical marijuana, so I did this journal publicly with that in mind, but this grow was done primarily to answer my own questions so I can refine my growing techniques, not to prove anything to anyone else.
And the nute lock out that only happened to the hid side, as I said before that kinda makes the results less than satisfactory IMO.
Both groups were in the same medium with the same nutes, so both groups faced the same issues, although the HID group was more affected by it. With copious flushing, the issue was resolved in both groups to the point where I felt OK with continuing the grow. I agree with you that for whatever reason the HID group was more affected, it could have had some degree of influence in the results, but I don't think it would be significant. Of course, I can't prove that, but in the overall scheme of things, I believe the impact was minimal.
As far as being neutral goes, this thread is filled with LED fanboys who don't dare say anything that might be a downside to LEDs and are quick to point out any HID issues.
well, I can assure you that I wasn't an LED fanboy until I harvested my plants a few days ago, but I certainly am one now
Also, the grower seems to have more experience with LEDs and less interested in the full potential of the HID system.
What I'm interested in is growing nice plants. I'm not loyal to HID or LED, or any other gear, because that wouldn't be in my best interest, and I think it's silly to argue about which technology is "best", because that's just too simplistic a way to look at things. What's best for me might not be best for someone else.
That's why I mention a second run, to be fair. I don't think it was a fair comparison based on the media problem that only one had, the hid.
Again, both groups were in the same media and faced the same issues, but interestingly, the LED plants handled it better.
This grow was more than "fair" enough to convince me that GLH's LED lights are a viable product in my grow room, so from a personal standpoint, I don't see any real need to repeat it.
It may be repeated in the future if I happen to be using the same combination of lights, but who knows.
And again, the results are some great looking smoke and in the end that's what counts.
Good smoke is always nice, but what counts most to me in particular on *this* grow, is that I've answered my own questions about LED lights, and that I now know that I can grow spectacular bud with them in temperatures that have my HID gear gathering dust in a closet.
There, I've said my piece and I"ll leave it at that.
Take it with a grain of salt.
I"m just as interested as anyone to see the LEDs become the mainstream lighting systems. I'm not interested in bashing the LED guys, in fact I encourage all and hope for success for all of us.
I welcome and appreciate your viewpoint and sentiments.
Let me start, I totally get where you are coming from.
Was the experiment scientific? No, it was missing was a control group. But if you really want to "prove" anything you would have to go far beyond a 2nd grow to get any answers. It would take several grows to produce enough usable and stable data (to compensate of unknown variables like the deficiency) to make a truly definitive decision.
In the end though, do we REALLY need to know without an ounce (no pun intended) of doubt which is better? Does one technology absolutely have to crush the other to prove it's worth? They both kicked ass.
What more could we have asked from such a wonderful comparison grow.
This grow is more than enough to prove that one can grow copious amounts of high quality cannabis with either LED or HPS. Beyond that is comes down to what system will work best for your needs, plain and simple.
