Mars-Hydro LED Grow Light Discussion

Thank you to all for your advice on the right lights for my 2x2x2m tent. particularly to smoke Sarah.
I was unaware of the 600w reflector panels being available with 5w leds, are these available through ebay Sarah, or do I have to order direct through marshydro uk?. Again many thanks for all of your advice.

If this was directed to me I commented the need of 2100 wall watts not light watts and due to the height of the tent the use of multiple lights, even four 1200 watt lights will leave a low light area between the lights if the plants grow over 30 inch in height and are in a 12 inch pot. If you think you need HPS I have a box full they don't even make good door stops and in my area won't get you $25 each due to the heat
As for four 600 watt no you will not grow a full tent but if you look at the posts there are some impressive plants being grown with only 150 watt lights not everyone here has the desire or cash to throw thousands on lights for basically a hobby
You guys are crazy....2100 WALL WATTS for growing some plants? Seriously, this is hard to believe and would also (at least for Europe) cost a fortune if some would need 2000+ real watts on light.
I can't say anything yet (I have 2x 300W old models but in a greenhouse with additional, real Sun and it's just sprouting)....BUT if you're so concerned about penetration I'd look into COB lights, possibly even those with the lenses! I am still pretty new to this but I understand that the COB lights with the focus lenses have the best penetration. Here too you would not need 2000+ real watts to grow some weed, I am sure.

Anyone else having problems with their website? Also need a recommendation on a reflector series I should choose for my 3x2x5 tent. Will the 96x3 work or should I go with 144x5?

you will get good results with the 96x3 i have seen great grows with less wattage but its hard to give the plants too much light so i would say if your not worries about heat for price then go for the 144x5. i am actually using the light in my 4x2x5 and have low heat and amazing resin production!! i wont have the biggest yealds but i'm a new grower and have made a few mistakes along the way, feel free to stop by my journal
hope this helps man

Which light are you using?

2 meters X 2 meters is a big area and you can grow and flower really more than "some plants" in a such area. this is the power needed to have full lightning in that area. most of growers want full lightning and best result, even if it is only for a hobby or to grow some weeds for ourself. with very very expensive led lights like kind led or hydrogrow or else maybe you can have full lightning with 1500W true watts ..... and with HPS you need 2400W and more .... for 2X2 meters area
yeah, electric power is very expensive in Europe. in Canada where i am, the cost is 1/3 or maybe 1/4 compare to the cost in Europe.

in Canada, 2100W at 12h day about ...... 50-60CAD .... 50CAD = 35 euros ....
at 18h a day ..... about 75-90$ .... or 55 euros

same here .... i look at their website very often and every days and this is very rare .... i guess they are updating their website
Cost is about $120 - $150 a month during flower (8 weeks) produce 3 to 5 lbs every 60 - 70 days local dispensary cost $175 a oz and like the little bird said Cheap Cheap Cheap.
You need 35 to 50 wall watts per sq ft of grow area for good growth with LED be it panel or cob main difference between amount of light is bud size, density, and resin production while it costs more the outcome can be worth almost twice and in as much as half the time. Some of us do not have a greenhouse or live in a area where growing outside is a option and electricity is still reasonable we all forget these posts are from anywhere the internet touches and what seems ridiculous in our area is normal in others.
Just realized I'm a member now WOW!!!!!!!!!!!!
Funny don't feel special no balloons or dancing ladies not even a glass of water in my face
Guess I will go play with the girls and tie their children down some more

im using there 144x5 in a 4x2x5 foot tent, im able to keep my temps low with just a small 10w duct fan. temps only climb 2-3 degrees more then the temps in my room.

No need for the glass of water now

Yes of course, just 2000W sounds high to me, at least for "a bunch" of personal plants.
By the way, this just as a side-note, I think Wattage, whether it's "wall wattage" or whatever Wattage is a totally meaningless figure. What does "50W per sq ft" mean seeing that different types of lights (LEDs, HPS, CFL etc) have a totally different light output per watt. Simple example, my living room LEDs put out as much, if not more, light at 4.5W as my Halogen lights which use 10x more, wattage means NOTHING.
You may even know that not even Lumens or Lux mean anything, I understand that the only useable number here is PAR, the light plants actually use. This is why I don't understand why people are looking at Watts, it just doesn't mean a thing.
Edit: Ok you say "50W per sq ft" for LED, so it's more specific...

ok then ....
you will get a very nice PAR(or light power usable for plants) for growing/flowering marijuana with 45-55W true watts per square foot with mars hydro products (others leds maybe different) ..... whatever the way you like, the important is to have enought light to power your plants ;-)
(old model series is better to use 60W &+ per square foot)
(all new model with cree leds will be very less, maybe 35-40W per square foot ... maybe)

yep, website is down ... maybe updates
definitivly go with 144X5 for your 6 square foots area ... 96X3 is clearly not enought.
try to use at least 50w true watt per square foot .... so 300W for your area ..... 144X5 consume very near 300W true watts so you are good (not sure exactly but little more than 300w i think)
