Mars-Hydro LED Grow Light Discussion

[CatfishKnight]

Not trying to influence the way you grow at all. Just letting you know that they are very forgiving plants. A bird could drop a load containing a seed on a flat rock and it would thrive

This is the tent after removing the 5 in the 1 gallon pots just before harvesting two more plants in 3 gallon pots. The Light Master mathematicians in the group would tell you that 585 wall watts in a 5x5 space wouldn't grow crab grass, but ...

Looks good. Looks like they luv it in there.

Hey Plugged. This Led and enclosed Grow Room is all new to me.
Learning by watching Youtube videos and etc.
Using Co2 I saw you can let it go up to 105 degrees, on this one video I was watching.
But a lot of others said around 95 degrees is better for the Co2 enhancement.
I guess I will fine out. Lol.

That is one of the reasons I will be trying one of my grown Pepper Plants in it first.

Plugged, what do you mean by: moisture evaporation from those 10gal pots the wet bulb temp ( RH ) may rise above your wishes. Higher temps?

Should I use 5 gallon pots instead?

Part of the problem with higher temps for co2 is that at 95-100f ambient room temp , your lights will be considerably hotter than that and it will shorten the life span of the LEDs (considerably) . I would use 5 gallon smart pots and get a dehumidifier among other things .

Co2 works in a hps grow because you can cool the lights without effecting the grow environment, not possible in led grow ,
And using the heat the lights produce to heat your room is very inefficient and is hard to manage temp control with this method , just my 2 cents .

Heat Will Kill LEDs....

Also your ambient room temp needs to be 83-85f in an LED grow as appossed to hps grow at 78f , leaf surface temp is not adequate under LEDs at 78f and needs to be around 83-85f for optimal growth to occur and reactions to occur inside the leaf . Under hps and co2 injection temps need to rise to 95-100f for sped up reactions to occur, this could mean that under led with co2 injection temps may need to be into the 100's , 105 or hotter , making your lights climb well into the 100's , I'm just not sure co2 can work in this environment without a way to vent your lights separate from the grow environment.

Peppers and marijuana plants are totally different and will react differently to light ,heat , co2 , ect...

I highly suggest reading about marijuana and lst (leaf surface temperature) and what is considered optimal. Not all plants are created equal. I posted a link in my journal that I can't post here that explains lst and marijuana as well as other plants and what is optimal.

Thanks , but think how well your plants can do.

Compared to my plants living in a hostel in Podunksville under a partial Martian moon subsisting on worm crap and rain water, yours will be in an all inclusive Caribbean resort soaking under three blazing equatorial suns soaking up nutrient Mai Thais and eating blackened Mahi and lobster tail.

Thanks. I will find my 2 or 3 gallon pots I used in the past.

This site will not let me post a link to where you can read this , they say everything is contained in This site and references to other sites is not allowed . But anyway check out black dog and look at lst , just read that , no one is saying to buy their lights .

You can look right here in the grow journals, two very good growers JohnnieJC3- Kosher Kush Sharksbreath Feminized Manifold Project and Supergroomer- Supergroomer's Revenge of the clones

 

[ugdfuiga]

Yep , but they don't own the equipment that that company has and the tests that were done by universities. Not All info is contained here , lol.

I'm just saying , quite a few people have asked , including me , to buy a spectrum meter $1500 and do a spectrum test , can't marshydro afford one ?

All you have to do is look at my grows to know we use marshydro exclusively, just would like to make the company produce better lights (remote) that I own , and provide some tests results , other than from growers who are doing the work for the company, show me the results, par... and spectrum, please

Sorry No pot size isn't it they can be big you need that for big BUDs LoL,, Its simpler than that, The dry bulb wet bulb jargon is engineering for how much moisture the air will hold at what temperature ! Hence RELATIVE Humidity. I think we try to maintain something below 60% maybe wrong I think I read it somewhere? I'm on my 7th clone event still ironing out the best combo's of Dirt vs Hydro vs Lighting vs Nutes vs bla bla bla havin a blast !!

Greetings,

Received a Mars-hydro 160 today. I would have rather just sent a PM to someone but since I do not have enough posts [not sure what that's about] I have to just post this out in front of everyone.

First impressions, well tell me what you would think guys and gals.

Box is marked Epistar, directions claim Cree. Me-clueless.

Apparently the remote function has got everyone confused. I have watched three videos on YouTube.
1 from Colorado's finest from here, one from a Meduser1, and the third from Mars themselves. My light functions most like Meduser1's and with each change in settings [seedling,veg and bloom] the light turns on, flashes three times and turns off. Looks like it stays on in the others video's so I assume this is a new change to the already cumbersome light, and quite frankly the directions are horrible. I have seen several complain, so I know this is not just me.

Not sure why we are using fish aquarium tech on a grow light, but is what it is.

I like, I would assume most people just want to turn on the seed or veg and have it on 24/7 and when I hit bloom I want 12/12 or 11/13 for the sativas. That said looks like I am most likely stuck with this now as when I ordered it, it had to be built and shipped from China, otherwise I would return it immediately.

If someone would be so kind to explain how the remote really works that would be awesome. If that is even possible...

I'll reserve any and all comments on how well this covers the area it claims, but I built a room specific to its claims and will be testing it here.

ya the remote took me a bit to get used to and i work in tech support so can understand how it is confusing haha i actually was shooting a vid to show how to program (should have that in a week) your own spectrum and set the timers for the programmed modes, came home that night from work and the light were off haha i had forgot to change it back to my correct custom mode and they were getting no light for the longest time. I do agree that there are things that can be improved with the remote, like having the temp/humidity gauge be on the light or something to that degree, be able to change it from Celsius to Fahrenheit and make pro gaming the modes just a bit more user friendly

My humidity is at 45 percent

 

[CatfishKnight]

Ok I changed from (3) 10 gallon pots to (9) 3 gallon. Lol

My humidity is at 45 percent

3 moist pots ? at 90 ,,, my 2 5gal fabric pots at 80 evap near a gallon of water in 36 hours under inferior lights ( 60x5 s)

variety of awesome girls that's the way to go !!

 

[arellanobrian]

And here is the Weekly update guys, was a little rushed in making the vid and was a bit hungover from watching the Bronco's play yesterday so sorry if i seem a bit off haha but on a good note Colorado is still undefeated

 

[Mars Hydro]

haha, Gnarl, there is nothing wrong. The remote controller will control the lights within 10meters in the same room and couldn't get through the wall.

Ok. LOL. What's wrong with me thinking you may have reason to have control over separate groups of lights in different stages of plant development? My bad.

 

[Mars Hydro]

I have to say, I agree with you. I have checked with the engineer. We need to reprogram every remote controller and rely on APP, which may not be achieved right now. I hope we can make it in the future.

Sara,
Imagine someone using multiple PRO lights all in the same room, but had each light in it's own tent. The purpose being to have a large, flexible perpetual system. Some may be running 18/6, some maybe 12/12. All with staggered, different timing. One light in one tent needs to be programed for 12am-12pm, another light in another tent right next to the first needs to be programed for 2am-2pm....etc etc. This is why different or selectable remote channels are needed. For those that don't want to run them all together with the all the same programming. It's cool that all lights can be programmed from one remote. Now MH just needs to make them act as individuals even when there are multiples.

 

[Mars Hydro]

yes... having read your comments, I have realized it. To some growers, this is a disadvantage. Now I am curious to know how it performs.

Ok thanks Sara. That is what Ruby told me too. I even marked my Remotes and led units #1 to #3 so I would know which remote went with what unit... Which means MarsPro will lose a lot of sales due to that... Growers want to be able to contol their individual lights easily not a work around with removing the receiver. Still bummed that we can't control them individually..

 

[Mars Hydro]

under this situation, the remote controller function of the light seems useless.

Heirloom hit the nail on the head with that statement right there. Many run perpetual grows with 2 or 3 tents and your flower tent needs a different light schedule than your veg tent which is impossible with the Mars Pro's current configuration

 

[Mars Hydro]

Hi LED Grow, please no worries. Everything has figured out. We have applied for shipment the day you placed the order, but it happened to be weekend, so the warehouse didn't update the status and we have to verify with the warehouse first. You can check it today and it has been updated. You will receive your lights soon.

I think i have a problem here.

Did order 2 mars 2 700w lights more that a week ago.
Recieved the tracking number for my package 5 days ago.

When i try to see where my package is on the dhl site,
i get this message:

(Not found): No result found for your DHL query. Please try again.

So i contacted support from the mars-hydro site to ask them to look into my order
and also check the tracking number they provided me.
I also mentioned that if i don't recieve the lights that i would like that they send me my money back.

And to contact me with any updates as soon as possible.

below is a copy of the message i recieved back from MH support just a few min. ago:

here is our return policy if you don't want the lights. Please check here Return Policy | Mars Hydro
As long as your lights meet the conditions, we will refund you the money.

What is wrong with this message???

No response to my question about checking my order or tracking details.

And..... for me to see my money back, i have to first send the lights back to them???
How can i send the lights back if i did not recieved them in the first place???

This is not acceptable at all in my books! ! !

 

[Mars Hydro]

thanks for sharing, Neil.

CatFish did you try setting one light and then removing the receiver, will it stay set and running with the receiver removed? If so screw the receiver in the next light and set it and remove the receiver again, do the same to the third light and remove the receiver. If you want to alter a light screw the receiver in and set it and forget it, would this maybe work?

I found this on you tube maybe explains more
