Apache AT600 led vs 1000w HPS Blue Dream Grow

Very nicely done and presented GG, clearly those AT600's are top choice, impressive, no contest imo against hps.

A big congratulations brother. What a stellar job. This has been one of the best journals ive read. Really excited for an all led run next time. Whats the plan, another 600? Busting out the good ol 120's again?

Thanks GG for the thread helps make pulling the trigger on a AT a lot easier!

Very nice GG,can't wait to see the test results.

the grow definitely shows that leds can replace the 1000 but im kinda bummed the gpw numbers arent a bit higher for both. you think the numbers could each be bumped at least .2 gpw if you ran it again?

thanks so much for your data and job well done

I personally think you should take into consideration the numbers were very well for 6 plants in a 4x4 area, organic nutrient regiment and no co2...thats just my two cents

Thank you very much. It has earned it's stripes for sure. Not even back seat for hps...totally off the bus.

Another at600 for sure. Then fill the "L" space with at200, my DIY, and some 120's. And try to get the IG in there somewhere too. I have big plans but not big enough space.
And....I have a couple things up my sleeve, but I got to find where I put that shirt...so we will see.
But I guarantee it should be a fun show.

Thanks Capt. I will do a smoke report too. And see if I can do some blinds on some friends or people at the club

Yes I could get it up for sure...but that has to do with me as a grower, not the lights I think

I have said it many times I am a 1.5(.68g/w))ish per light guy...always have been. I've bumped it up to 1.75(~.8g/w), but only once and the other times with that strain were over 1.5, but not by too much. And that was with multi lights. I was not originally satisfied with this run because I thought I would have been close to 1g/w with hps, but I just don't and never did. I'm getting more proud of it the more I come back to reality(my reality). The were both solo lights with no help and pulled solid numbers. If that was a true 4x8 garden with no divider I think I would have really had a big pull. But all things considering, not bad at all imo.

My basic statement to all is... for me this at600 does everything a 1000w hps does/used to do for me. If you are a person who yields more than I do with their hps...then you will yield more than I do with an at600 and I would expect it to replace your 1K like it did for me.

Next run will also have co2, which I expect close to 20%+ yield bump...I personally believe that the light(form both) was not fully utilized by the plants because of a lack in the other factors such as co2.
Bigger pots+better soil+co2+no divider=even bigger yields and buds for me.

I will have a diffent strain in the mix too...but BD will be around too.

I think you said a while back that the divider probably cost you a whole row of pots...next time you'll definitely get the 1g/W you want, I'm sure-especially with all the available space and the CO2

Congrats GG! Scientific all the way. I like the style and hope this trend continues.

should organics yield less in your opinion? and i've never used co2 in my life so wouldnt let that alter comparisons to my experiences. the plant count/size of plants is definitely a big consideration along with pot size and the soil mix as he did state would be improved next run.

now i do remember the talks bout how you werent happy with the soil mix and would be altering for future runs. wasnt trying to be that guy who walks in and turds on such a wonderful grow.

you pulled roughly what i pull from my 1ks now. running perpetual always means my girls get a bit too much or a bit too little veg time and nothing is ever ideal. doing it right for that optimum yield would mean throwing off my much needed schedule. part of me feels im wronging them in this way lol

my only 1 gpw pulls were when my garden was small and simple with each plant getting personal care damn near every day. flowering them exactly when they were ready and not a day later or sooner.

its nowhere near this more controlled experiment you just pulled off but currently i have a 4x4 tray under a 1k and a 4x4 under an indagrow 420 with a 4 tube t5 to cover the whole space. 35 days in both sides look damn near identical.

cheers

Thanks really cool...you got a thread?? I have an IG too I am trying to get back in the mix.

I want to do more than 1 side by side at onces...get like 3-4 different lights in my room but I don't have the ability to cut up my room from cross over like it is one on one like it just wasI'm really starting to want to remodel. No dividers is the best for me...but for the side by sides and lights I would be doing their could be big percussions and I would want them to be as accurate as possible like this one was. So I am in a predicament if more comparisons are my goal.
But a fully kicking and yielding led room would be no problem.

i used to run journals and share my gardens on forums but "friends" decided a half pound of medicine for some sick people was worth more than those peoples' health and my friendship. been too sketched since to share any gardens openly. sad story but far from the only medical grower that has been through this.

i hear what you mean about maintaining the control of having dividers but sometimes the right choice is not ideal in all aspects. the crossover between will surely flaw the results but we both know that the differences will still be there, just not as pronounced or pure.

not yet sure whether ill end up with a mostly induction setup or led but the sodiums will be meeting a similar fate to those you have collecting dust no doubt.

I am in the same boat GG. Just got my most recent LED numbers .96g/W (dissipation Watts). Organic soil, no CO2 and a bunch of random varieties from seed. My HPS yields were never over .5gr/W and more often .4gr/W. I am very happy with the results but as always I know there is some room for improvement as I upgrade my panels to higher efficiency bins and try to improve as a grower.

As far as fertilizer goes, if I try to push yields higher, quality suffers. I get dreading or buds that shade themselves out, bud rot, less frosting, less flavor and in the worst cases, overfert can cause farmy smelling buds. I have been really stingy with electricity in veg (for no reason) and with the amount of soil in each bucket (to get a timely finish with no dreading). The next thing I plan to try is more soil/veg up bigger for more root mass and cut the underbrush a bit more. Basically a taller canopy since LED gives me more headroom and the ladies that get tall seem to yield best for me.

Anyway, none of my friends are kicking out 1 gr/W with their HPS grows and I can only judge by what I see. One guy got .9gr/W with some huge yielding Island Sweet Skunk but the nugs were not frosty or potent and had no flavor/smell. They took over 10 weeks to come to a white haired "finish" so that really affects the validity of the g/W. Also worth mentioning, the nugs were not dried to the extent that I dry mine. He was in a rush to cash crop and some of the moisture was still making its way out. I am interested in ladies that can truly finish in 60 days or less and kick out nugs like this and stink to high heaven

Wowzers...Dank level 9 right there.

I'm glad I am not he only good grower not hitting that mark. I am totally happy if that is where I stand...but all those big numbers being thrown around makes me think I'm struggling to keep up.

A little cob action might get those up even higher too.

Can't wait to see what you can do with some top notch COBs!

that bud look like it was tossed in a tub of sift and shaken up. gotta agree on leaning quality over quantity (way overused saying i know) but im always trying to find a knockout whos just a lil chunkier than my best cut. i have 3 phenos of super critical that are impressing me as well as 2 different cuts of kalashnikova. still in the process of narrowing down to one cut of each. i know GHS isnt backed by most top growers due to arjans apparent greed and classlessness but this super critical is fuckin awesome. dont think ill be dropping it anytime soon. my patients love it and it makes some veryyyy potent oil for cancer patients.

The HID guys gettin big gpw numbers are running a bare bulb vert setup. Iv never personally seen close to 1 gpw using HID in a conventional overhead lighting scenario.

Come on yu know yu been smoking those trich encrusted buds... led taste better dont it??????????

Hi Greengenes. I liked your thread and the results, it inspired me a lot. You stated it above...You are a 1.5 ish per light guy... I was wondering... Some people reach with the hps 1.0 grams/watt. You reached 0.66, that means that a very good grower has results 50% above yours with hps (no offence). What would happen when those growers would grow with the AT600? Would or could they improve your ledresult with also 50%? So reach 1.5 gr/watt? Of would 1 gr/watt be the max possible?

Happy, I get what you are saying, but I am not sure I buy into the idea that both GG and I are simply poor growers. Neither of us are neglecting our gardens or failing in any major way and we have both been at it for years. I have been working in commercial greenhouses since the age of 8. I am sure there is some room for improvement of course, but I doubt that we would increase our yields by 50% by being schooled by these expert 1 g/W growers that we hear about.

That said, I do believe 1g/W is possible with HPS, 1.5gr/W with commercial LED and 2gr/W with diy LED, but as jbone said it may require vertical bulbs, brand new bulbs every cycle, long veg times, long flower times, and likely lower quality nugs like the giant skunks I mentioned above. The point is, if you make all those sacrifices and get 1 g/W, how much medicine did you really grow if there is only half the amount of cannabinoids?
