Mars-Hydro LED Grow Light Discussion

[Mars Hydro]

Your light is a Mars II 400 ,the coverage is 2.5'x2.5',you can go with a 3'x3' tent.
How many plants you have?

I need tent advise real bad.

I'm limited height wise to 6', and I see 3 tent models (2' x 2', 3' x 3', and a 2' x4') on the Mars Hydro website, each with the 6' height I need. The problem is, I can't make up my mind.

I own a Mars 2 400watt LED that, according to the Mars website, is suited to all of the tents mentioned. I'm hoping someone with experience in this area could chime in and help a fellow member out.

*The tent in question would be used as a flower tent*

All I can think of is space needed for a carbon filter and fan, small oscillating, or stationary fan and a small humidifier (maybe) and of course the green ladies.

Any/All helpful tips would be greatly appreciated.

You make good point.

Led lights efficiently illuminate a square shape.

HID lights efficiently illuminate a rectangle shape.

Since you use LED I would say go for the 3 x 3 tent

The reason I suggested the 3x3 over the 2x2 is only due to the space. Much better to go a little bigger than you would need / want and have the space than go smaller. 9 square feet seems perfect for your light and will give you a little more room to work with in regard to heating and odour controll

If you need to know anything,you can get answer here.Our friends here are very kind.

Wow, that was fast. Appreciate the input

I guess we can not use it as the soil on the farm,every season just add nutrients to it...so you reuse75% of it,and add 25% new.

I reuse about 75% of it.

I checked our international warehouse stock information,3'x3' grow tent is in stock.You can place order at anytime.

Makes sense to me. I've never owned a grow tent, this should be interesting

 

[TorturedSoul]

My apologies, Mistercpp, I - somehow - was thinking that you had TWO of those lights. I guess I saw "Mars 2" and thought "2 Mars," lol.

Again, I am sorry for misreading your post.

 

[Mars Hydro]

I'm back,thanks for your help.

Ah, but Mistercpp mentioned that he has two LED panels - and two squares, placed together side-by-side, would form a (non-square) rectangle - not a square.





Ouch. In that six feet of height, you'll have your LEDs (with at least some space above them being required for airflow to their fans and the hanging hardware), your plants' pots (or reservoirs, if growing using DWC hydroponics instead of soil)... and the actual "above ground" plant matter. I feel your pain. I am also contemplating things here - although I am lucky enough to have a higher ceiling (and that my Mars-Hydro tent appears to be approximately 6'7" tall (size is listed as 120 cm x 120 cm x 200 cm)).





My guess would be that you can assume the smaller tent - and its area - that is listed as being compatible with one of those models of LED panels... would be the footprint which is most suitable for the flowering cycle (and that the larger tent(s) mentioned would be suitable for vegetative growth using one of those panels). I just checked the specifications of the Mars II 400 and saw that it consumes 177 watts. My (somewhat uneducated) guess would be that two of them, placed side-by-side, would be adequate for flowering in a 2'x4' space (tent). That would give you 44¼ watts per ft.², which is within the range generally given for wattage requirements when flowering under LED lighting. Again, this is my guess, but I'd guess that this would give you an adequate setup. You may find it beneficial to leave a slightly larger gap between the two panels than between either panel and its closest tent side, so that the footprint does not drop off too much at the sides of the tent; the "third light affect" ought to help in the middle, where the (declining) footprints of the two panels can overlap and combine into a stronger amount of illumination. Again, this may be adequate all by itself... But you can always supplement with CFLs for a tiny amount more light (and to further "tune" the spectrum, if desired).



If you really need a humidifier for your grow space, would it be possible to place it outside of the tent with its output directed at one of the vent openings? Perhaps with your oscillating fan directly in front of said vent (but inside the tent) to help move the moist air inside and spread it around?

Matching everything up for the best complete system is sometimes a challenge. It is good that you're thinking about what size space you can properly illuminate, rather than "how many plants?" - then you can fill that space up with your plants .

Sara will be back at work in an hour or so, and will be able to offer her recommendations/advice as well. She is very active and helpful here.

Haha,i also thought he got 2 lights at the first time,when i went back to check again,it's a Mars 2.

Maybe he should buy another one - then he can go with the 2' x 4' tent, lol.

 

[Mars Hydro]

Thanks ,i will check.I got some problem with my internet here at this time,i can not read those pics.Maybe few hours later can.

Here you go Sara, you asked for my photo a couple hours ago, my girls posing together 8 days ago under (4) Mars Reflector 144.

[Quote Sara]:
Welcome back, it's nice to see you around here again.
@650shelby.Congratulations! You are one of those legal licensed grower,wow,that's great!
" No chemical fertilizers and no chemical pesticides allowed in my home." Do you mean you do not need cal or mag? Organic cannabis, sounds interesting. Do u have pics of them? We would like to see your organic product.
Sure, our team will check your work, I will visit your journal.

 

[Mistercpp]

Sara, I asked a few questions about the tent in question but it's in another subforum somewhere, I lost the darn link somehow.

 

[Mars Hydro]

We measured the PAR value at the coverage 3.6'x3.3',at the height 18inch.
Yeah plants like more lights,high intensity.

Sure looks to me that the effective coverage is 2'X3' at the very very most. A par of 200 and less isn't going to flower a plant very well at all. 500 and up to about 1200 is where it's at for flower. Those par readings are with no plant in the picture so when there is a plant in there the par readings at the edges will even be lower because of the plant in the center.
This looks to be nice for a 2x3

 

[Mars Hydro]

This sounds a good plan.haha

Maybe he should buy another one - then he can go with the 2' x 4' tent, lol.

Thanks TS. Since it's just me growing/using the meds, I'm thinking of trying some of those autoflower strains in either the 2 x 2 or the 3 x 3. Once I get a few harvests under my belt, maybe I could spring for another light or two.

Good tip on the humidifier, the fan by a vent just might do the trick..I'll have to give that some thought for sure.

My height limitations suck to say the least. It's going to be a basement setup until my grown children move out again. Who knows how long that's going to take.

 

[Mistercpp]

It's no problem.If you need to know anything about our products,you can ask me at anytime.

Guess I'll re-ask in this thread, I won't lose this one..

1. The 3' x 3' x 6' tent - Is it shipped from the USA if shipping to a USA address?

2. Is there a coupon/discount promotion going on for this tent?

3. Would you happen to have a ballpark guess as to how much the shipping would be for said tent?

Thanks in advance..

 

[Lookout Bro]

I put it outside in my yard. I sometimes mix it with other dirt to plant trees or bushes.

so after you finished your first grow , you will just throw away the soil? Why? Add more nutrients is not enough?or mix with some new soil ?
