300W LED vs. 400W HID Demonstration

hmmmmmm, those look interesting, but not sure how you would use one in a tent like mine because the exhaust fan has to stay on to keep temps down.

I guess if you were venting an HID hood independently of the tent you could use those, but how would you use one with an LED or T5, on non-vented HID hood?

If you have your tent in a sealed room maybe, but the website says it's good for 4-6 plants, so that sounds like a smaller space.

ya i have to keep my exhaust fan on too, always, i cant let the smell get out, so why exactly would this be a problem, would it just suck it all out and not fall to the plants?

i got my tent in garage.4x4 tent.

how about if you put the bag out side your tent, up against your intake? the only thing about me doin that, is i have a filter on my intake.

you're very welcome!

I'd love to run that heat test for you, but I'm concerned as to it having some effect on the panel's lifespan.

Maybe Mike can let us know if that would be an issue or not. If he says it's OK, I'd be more than happy.

Well if I recall the lights are rated to 105 or so, so I imagine up to that wouldn't damage them, but your right, to go over could be risky. I am sure that given time the light would at least heat the cab to 90 to 95 so I suppose ac of some sort is still needed in a sealed environment.

My new spectra 120 has been rocking, it needs a proper tent/cab still but in the open the things kicking the cfl cab I got. Much faster growth to spite the cfl cab being a better environment temp wise.

Looking forward to the dry weights.


Judging from the coverage in your tent (2.5 ft by 2.5 ft tent right?) what would be the ideal and max tent size?

Thanks ss..

I think on my next grow, I'm going to try dogsnova's suggestion to use some clear incandescent bulbs for the last few days and see how that goes.

There is something very intriguing about that idea.

It's really OK with me if you think the grow is fundamentally flawed and discredit it, so I have no interest in proving anything to you or in spending energy convincing you otherwise ;).

Wow. Not really what I thought you would say. ?

I was hoping we could get into optimizing each system and discuss that a bit.

doing another run and combining data etc.


All I can say is........:cheertwo::goodluck:

All I know, regardless of all this "keep it equal" stuff, is that the 300W LED made some kick-ass buds. They appeared to be equal with the 400W HID, but even if they're not, or even if they're better, they still made some smokin' buds. All doubt should be removed as to the effectiveness of LEDs, IMHO.

yes sir! SS is on happy grower right now with all that killer smoke from both sides. its a win win

I love it when that happens :)

IMO, the final yield difference if any, is second to better aroma/taste, and
third to stronger, spacier, longer lasting high :yummy:

people say that, but up to what point?

assuming there wasn't a huge discrepancy, would you take a 50% hit in yield for that better aroma, taste, and high? how about 75%?

if I ask myself those same questions, I get kinda squirmy, lol

would take 75% loss in yield if it were Red Bud thats for damn sure.lol.

Saturn, Whenever you are ready to duplicate this grow and spend the time, money and effort to prove your point I'd love to subscribe. In the mean time SS has already stated it was for his own personal knowledge and in doing that was nice enough to share that knowledge with us. Many people learned valuable lessons on this grow. Every one had input and many informational discussions arose from it. I find it hard to believe that you could do much better without having many thousands of dollars and a large warehouse to do multiple experiments to get a finite answer which would still leave people asking questions. That's the beauty of it. You will always keep learning new things and improving on other facets that we thought were great already. When you get that warehouse going let me know, we'll love to watch. By the way I've never owned an LED light. But I tell you this. From viewing the results although not to your standards, I will definitely have one or two before this summer hits. If you look back on this thread you will see that I was favoring the Hid most of the grow. Now that I see the final results, I believe! I'm not saying that the LED side kicked the HID sides ass but it definitely grew as good if not better quality plants then the HID. Keep us posted on the warehouse. SS is nice enough to do this experiment at the risk of loosing yield and quality which due to his outstanding care and knowledge didn't happen. You will find very few people willing to risk 3 months just to help everyone else decide. How many real side by sides have you seen? Google it up and you will be hard pressed to find many quality ones. I'm not trying to bash you but if you could do better I want in on it.:goodluck:

SS you did a great job on this grow.

Where does one get those little meters for the curing jars? Those would be extremely handy.
Click to expand...


you can find them on ebay by searching for "RH meter" or "humidity meter".

They are very handy. I'm going to order a few more.

There's also another product that DocBud told me about called Humidipaks that look very interesting.

Irish are RedBud seeds available anywhere? And are you saying you like DNC better?

I haven't seen Red Bud for over 30 years but sure would love to see it again.

Once again SS, you make me think :hmmmm:

I take a 'hit' with PE compared to GWS, for market acceptance. Wish I didn't have to. The powerful reek that I uncomfortably deal with is another burdon. Mea culpa, and I won't compound my error; when I grow 'better', it stays at home unless the money's right. Spoiled stoners!

With excess on hand, I smoke .5g/day. 'Regs' work for me just fine. ;)
 
re: GrowLEDHydro 300W LED vs. 400W HID Demonstration

SS, if possible, id really like you to do a more detailed explanation of how you divert the stretch energy horizontally, and prevent them from stretching vertically.

Your last post explained the theory, but its the technique im really after!
If i get my plants to look like yours, i will be one very happy person :)

I skipped back and checked it see if you netted them off, but it didnt appear so, however, i saw you mention LST, and i would really be interested in knowing how exactly you went about it, in an much detail as possible,
you mentioned tying them down, but im not sure exactly what you mean by that.

As much and detailed info on this as you can provide would be greatly appreciated!
