Mars-Hydro LED Grow Light Discussion

96X5 will be good for 2X3 if you want medium light power. for full light power you need more and as you said 144X5 will not fit your area. a mars2 700W maybe a good option for full light power. but maybe a better option is to go with 2X old model 300W. this is what i have at home for the same area and doing very good. always better to have 2 panels instead of 1 for better light distribution. 2X 300W will be very cheap too.

What light would better suit me for my grow tent (3ftx2ftx5ft)? The 96x5 or the 144x5? Temps will be an issue but only during summer time. I only plan to do 2-3 plants max. Since the tent is more of a rectangular shape I just feel the reflector series will provide better coverage than a Mars 2 series. The 144x5 will almost be the same length of the tent which i feel like might be too much.

Thoughts?

Thanks all
 
wow, I could not say better... genetics! can not be more coincident!!! and YES, it is a weed, that I grow outdoors for almost 15 years, and from exactly the same strain from the same top vendor in one year I harvested 500gr+ from one single plant, then next year I harvested 40grs from one single plant, as to repeat from exactly the same strain from the same top vendor. Again: same vendor same trusted, genetically stable (skunk!) strain in one year yields 500gr, other year yields 40gr... there are a huge amount of shit strains out there: you can get 600gr+ 35% thc, etc, bloody advertisment, but you got a trash plant that is not even able to stand on its roots, so weak and genetically unstable, what do you expect??!
buy quality seeds, bottom line, then find the best single plant from what you got and clone it for life...

I have seen posts where the size of buds from LED'S is questioned and while I do not want to get involved with that argument I want to post some pics of what I have experienced in my current grow.

So who's fault is it when our grows are not as large as what we expect ?
Seed vendors - they show us what we want to grow not necessarily what we get
Light Vendors - each is the best just ask them
Nutrient manufactures - it will turn a Daisy into a Redwood really it will
The Grower - If 7ml is good than 10ml is better, test equipment is not important, It's a weed stick it in the ground and harvest a Kg, Nutes? MG works on my tomatoes beside those others are too expensive, Let's alter the growth cycle, pull off all the leaves, tie it down, break branches then wonder why it is growing slow.

Bottom line is GENETICS and phenotype are the most important and that can be different from seed to seed then it's up to us to provide the proper environment, nutrients, water and control anything else that pops up:thumb:

You are right on topic and made a important point even with the right equipment and a lot of time a bad plant is still a bad plant
 
Check out my journals. My last 4 plants to come out of my flower tent under a Mars 900 and I got about 15oz of hard dense bud from 4 different strains. :peace:

I've tried to find your high yield but thus far can only find a 81g harvest from a 400w M2, so that's under 0.5gpw actual.

I really don't want to come across as harsh here, but are we all somehow now happy with that kind of gpw??! I have friends who are consistently pulling 1.2gpw with HPS, time and time again, and yet somehow 0.5gpw is now being looked at as ok?

I documented my grow from start to finish and was honest throughout, and quite frankly i was hugely dissapointed with the harvest......and the more i read the more i am convinced that 0.5g wasn't actually that bad for these lights.

Sorry guys, but i'm not going though all that effort when my growing buddies are doubling, if not tripling my weight by using HPS.

As i said, the standard spectrum was great in veg and produced some gorgeous stocky plants, but they failed to deliver in flower. If you're happy with 0.5gpw or less, that's fine, but i for one am not.

Just my 2 cents.
 
LOL yes Tony the weather here the past 2 weeks has sucked big time. Rain, overcast and humid. We might have seen the sun here for all of 3 hrs in the past 2 weeks. And its not be good for my indoor girls, found mold on one cola today. I only have another 1-3 weeks left on these girls so hoping I caught it in time and the measures I put in place keep it from spreading.
 
btw, back to the topic of this thread Randy, were those nice buds grown under Mars lights? :)

why don't you have journals?

simply use more led panels ..... maybe this is not enought for your high rating setting. try to use the same watt as HPS .... or even 10-15% more ...... will still worth it cause leds produce very less heat, and heat is very big problems for all growers.

USE MORE LIGHTS POWER ... as many panels as you can instead of only 1 big, will be better light distribution

Perhaps you need to look at my journal mate....but thanks for the advice :/

I can't, since I do not own and run any led lights yet... but very soon... still looking around.

I'm just saying with this set you might have grown decent quantity, at least on the basis of what I see in some other Mars journals. Anyways, I'd be happy with 0.5gr/watt for first grow.

Tell me about it.....anyway no point crying over spilt milk.

Thanks for the input buddy! I checked specs again on that 144x5 and i would have 1.5 inches of room on both sides of tent length wise if i went that route. 2x 300watters is not a bad idea seeing how cheap they are. That might just be the way I go! Thanks again!

'Tell me about it' is just a saying we use in the UK....it means i agree, basically it's sarcasm.....sorry i forget sometimes that this is an international forum!

I think if i switch things up a bit there is no reason not to hit 1gpw+ with my setup....as i said these lights are great in veg, but i'm aiming for bigger things in flower.

Just my opinion.
 
yep, didnt look at your journal before sorry ..... this setting seem very good but if you have 5X5 and you have 2300W of panels .... you can add more, even if it "seem" full. 3000W &+ for 25 sqft maybe better for very high rating settings.

I definitely would give a second shot for those leds... I did understand sarcasm in your post, actually I tried to be the same with mine :)

So basically you're saying forget HPS. Just throw as many wall watts of LED at a grow and you will achieve more grams per wall watt? What utter nonsense. You can't truly think that it's right to recommend 3000w of LED to gain a decent gpw when a lot of people are moving to LED's because of lower power consumption and less heat? I'd recommend that you have a think what you are saying before sliding away down that slippery slope of madness. 3000w LED would have more heat and power consumption than even a 1000 watt HPS. I still don't think that the gpw would improve either.
 
somes use same power or more power than HPS .... you still save a lot cause of ballast, ventilation, A/C and etc

maybe make no sense for you .... make sense for me

i really beleive he can get more grams per watt with more power everywhere, even if you dont understand the logic behind ...... you need around 1500W and more of HPS for that area, so 1350W and more of leds is almost the same and not overkill .... for very high rating settings

using the same watt as HPS or little more is not stupid too .... cause leds have many more advantages

me too i beleive i need little LESS than HPS .... but somes are using the same .... maybe they are right


never forget that marshydro panels are medium quality products ..... going for the same watts as HPS with medium quality product .... is not stupid .... its reality for somes


no, 1350w true watt of leds will not produce the same heat as 1500W HPS ..... not even the 1/3 .... nothing to compare
 
Hi doozy just want over to your journal. I hold my hands up i went strate to the last few pages after the first page. Btw some setup you got there well dialed clean n tidy how it should be. Last page you mentioned your first actual weight and touched on what you expected the second and third stage harvest to be. Question is what was the final dry weight altogether? If it were around 500g as you thought then I get your pist with the result with that many panels although I would be happy I think. I understand also wat your saying with the 0.5gpw it does seem to be the target for most. But again see why your disappointed with it after all your training. I wouldn't give up on the leds. I would give it another bash. And I wouldn't add any more panels. For that space I think it's spot on. Specially as wall wats isn't as big of a thing with led and lumens/lux etc it's hard to find the perfect amount of light but I reakon uv got plenty. U mentioned less topping and bigging colas. Give it a go and il be sure to pull up a seat.
Iv grew for a fair few years now and iv never hit better than 0.7gpw. I recently bought a mars 2 1200. But only put it in the room a couple weeks into flower so can't get a good gauge yet vs hps. Next grows led start to finish. Sorry about the ramble
Peace
