3000k or 3500k ?

Bmac1 · Sep 13, 2020

I am about to make the switch to LED lights and a new set up. I am going to have 2 4x4 tents on opposite lighting schedules with a HLG550 knock off in each.

These are going to be flowering tents primarily but I do expect to veg 1-2 weeks to settle new plants in when they are potted up and then switch to flower.

I know that 3000 is better for flowering and 3500 better for full seed to harvest and 4000 for veg but I am wondering if these 1-2 weeks of adjustment time/ veg in the flower tent would justify getting 3500 lights or if I should just go with the 3000.

Any input is appreciated.

Growing clones under 3500 or 3000 K is no difference here mate. Same yields indistinguishable buds. 2700-3500 K with high ppfd always produces short internodes compared to what you will see under HID
(That said I buy 3000 K, when that's not in stock I'll grab 3500 K

I can't see there being too much difference. :tiphat:

I also think there is no big difference.

Maybe you should have a look at our FC4800, which is suitable for 4x4 grow tent.

I think if you are a guy who is selling leds, you should KNOW these things, not THINK like others do. Because you should have done tests and have data. I'm in a way appaled with the lack of knowledge from the mars hydro guy, seems like the company is learning by reading this forum, which is not even having a scientific debate about it. Otoh it's normal and expected in this kind of market. Sad but that's the state of the world.

Cheers

yeah that right 4000k is for vegi and 3500k for both vegi and flower with QB LeD light

Ciao Koondense
While I do agree with you, I would like to point out a few facts which come out of cultural shock or cultural differences

In China people dont consume or grow ganja nor any other drug, the ones who do are foreigners. In China they learnt the hard way the consequences of the Opium wars and it certainly has a lot of influence on chinese people attitude towards drugs. In China people love buzz. So this is a foreigners market
The forums become a source of knowledge for something there is not enough credible scientific papers about
While I agree and I also think that sellers should know a little bit about the products they sell, in reality salesman sells and part of the selling is to hype up at forums and think like customers do.
The engineers are the ones who should or are supposed to do all the testing and have the scientific data and answer your questions. The correct thing to do for the salesman when a customer has a technical question is to ask the engineer for the proper answer

All chinese companies selling products related to cannabis growing or smoking, dont have a clue about how their products work simply because they dont smoke or use cannabis
Man, it is a real challenge to make a good product for an industry you know nothing about. Of course everybody will copy and make a similar product which is being regarded as good quality. Copying a good product is part of business everywhere in the world. The real challenge is to copy and improve it

There are even ganja breeders who know nothing about the seed they make or select. And bullshitism is at the order of the day in the canna world

I personally dont think the engineer will have an answer for which one is better 3000K or 3500K since they dont grow nor smoke test the product these lights grow

We saw something similar during the ecig revolution...

I was open to Mars in my room just not in the configuration you/Mars wanted. When I pitched an alternative situation you stopped responding. That told me everything I needed to know about dealing with Mars. A "no" would have been suffice.

Not to mention the fact that the 4800 is almost twice the price of the lights I will be buying this week.

Switcher56 · Sep 14, 2020

... they/he/she reminds me of the current presidential race! Anything positive mentioned from a delta mfr, they are out of the closet. Been there, done that and have several t-shirts.

Ahhh, the power of the mighty dollar$$$

Hi funkyhorse,
i know how they operate, been watching it for many years. It bothers me a bit when it goes on and nobody says anything, i feel compliant to their methods which i'm not. It's easy to copy and make same products with low paid workers while you don't invest in research to build your own product, i just can't stand silent while this guy jumps in every thread posting links without shame.
Fuck that, got no sympathy for this kind of business practice.

Cheers

Once upon a time there was a New Yorker who, invented a vaping device called the "Empire". He had a hard time keeping 'em on the shelf. circa '11/12

I attended a vape meet in Clearwater Fl, summer of '12. 2 Individuals of Asian descent (trying to be PC here) were asked to leave the meet, because of intellectual property theft and escorted off the property.. The Empire wasn't the only device they were after, nonetheless, we digress. Moving right along... 30 days later, the K-100 version hit the streets, the Empire knock off. They were identical in all aspects!

This business practice is very common in Asia and is calling touting https://en.wikipedia.org/wiki/Tout
People around Asia dont understand touting is annoying for westerners or at least for you or me. You cannot walk in Shanghai pedestrian Nanjing Rd without being sorrounded by hordes of touts offering all kind of services and goods.

People from all over China get attracted to Shenzhen because of the higher wages being paid there. I doubt they would find enough workers for low pay like it used to be 15 and even 10 years ago. Shenzhen tripled its size since then and it is not a cheap city. The times when Shenzhen was a calm fishing town are long gone

Having traveled the world I can attest to that. What we see on some movies is, "a fact Jack"

SuperBadGrower · Sep 14, 2020

Valid points on both sides IMO
I was gonna say, there's probably little incentive for them to hire more people for the purpose of doing illegal weed test grows in China :biggrin:

(Parts of) USA and canada is luxury land in this regard... the rest of the world is forced to advertise lights and tents for growing a bunch of peppers.

The methods & scale needed to be able to make generalizations is not to be underestimated, I guess. To perform research that gets the kind of high certainty results we're after is not so straightforward. Just the elimination of other variables is the tip of the 'methodological iceberg' if you will.

That said, posting for the sake of posting is kinda lame.

What? Why do you suppose they manufacture both if no difference?

If you do happen to go with Mars, realize the money you save isn’t everything....I had one crap out on me within the warranty period but couldn’t get them to send a replacement. Buyer beware, that’s all.

Same thing happened in the ecig market. It cost more to return (on your dime) than what the unit was worth. So basically their customers had to eat their Chinese crap and, just for the record, it is not ltd to ecigs and grow lights.

warranty...this fuker touts a '3' year...BULLSHIT... here's how it reads
''We offer a 3 year extensive warranty on every grow light we sell.Free warranty for lights within 1 year.Buy with confidence,buy Mars Hydro.

and
''notice: within 1 year free repair and shipping. 1year to 3 years : you pay round trip shipping charges, repair charges and handling charges, we cover component fee''

i'd NEVER buy anything from this MoFo... sorry for the rant, but as u can see it pisses the shit out of me...

SuperBadGrower · Sep 16, 2020

It's strange if paying customers can't be serviced (edit: served? Lol) when half the internet is shilling mars lights they get for free. BTW anyone with 100 sqft of grow space and still needing to shill for free entry level lights need to check themselves. I can list like 6+ youtube channels doing this just off the top of my head. So sad.

Wow seems this thread got heated

I would just go 3500k

If the Reds cost extra don't bother, they are shitty epistars anyway and U don't need them

Good luck

Also if the budget allows consider doubling the board to driver ratio on those cheapies

Will be quite efficient

3000k or 3500k ?
