Mars-Hydro LED Grow Light Discussion

[Mars Hydro]

I will be there to help that friend later

Sara! We are trying to help a guy in another topic find lights for his budget, and I wasn't able to find information for him if there are current promotions for 420 members, so I thought you would be the best person to help him pick the lights he'll need for his grow, and to fit his budget. This is his topic: Found a case of 100 led-bulb @ $5 each, any good? Pic included..

two mars II 400w would be better

Hi Everyone.

I'm kind of new here. I have read a lot about the Top Led grow lights and have spoken to Sara, she seems lovely. I am looking for some feedback!

I have a 2x4x5 tent and I was wondering if I should get 2 x Mars 2's OR 2 x 93X3w reflector LED's? Which would be better for the space and yield? I also plan no growing some veggies and herbs in the tent if that changes anything.

- Also, does anyone have proof of concept for each of these lights?

Thanks in advance everyone!

Am I spot on or not?

Hi Anna Lee,

We spoke before about the 1200 watt mars ii light. I have decided that is not the best choice in lighting.

My reasons for this are because of:
1. Spectrum - I know if you look at a spectrophotometric analysis of photosynthesis it looks like plants don't really use green. In fact they absorb green about 60% as well as they absorb red.

a. The light bounces repeatedly against the structure of the plant giving it more chances to be absorbed.

b. Cartenoids - in the plant which are in a much smaller amount then chlorophyll DO absorb green very well. They pass excess energy onto the chlorophyll and they are responsible for terpenes (smell) as well as flower taste. They also will dissipate excess energy and are the reason your LEDs have been shown to bleach plants when they are too close. If your lights contained green I do not think this would be an issue.

2. Watts - 5 watt chips do offer more penetration but they are much more expensive. They also require larger heat sinks further driving up the production costs.

a. The most efficient indoor style of grow is Sea of Green or Screen of Green. Since the canopy is so even and lush the lights do not need penetration and can be kept very close so that light is not wasted. 3 watt chips are most adequate for this.

3. Size - The larger overall wattage of this light means that fewer are needed, but one could purchase 4 300 watt 3 watt chip LED panels for the price of one Mars ii 1200 watt. Having more lights to cover a smaller area allows for better light distribution over the canopy and will result in better results when flowering.

The problem is that green LEDs are inefficient and use more electricity to run. The solution is to use a high quality white LED. It contains the entire spectrum of lighting which is very beneficial to the plant. I understand white is also not as efficient as red LED's but the benefits definitely outweigh the negatives.

I've spoke with Smoke Sara on 420 Magazine and no one has tried 3700 Kelvin as the entire spectrum before. This is a warm spectrum that is very good for promoting flowering.

The lack of a blue spectrum makes this a light which would not be very good for vegetative growth because without blue the plant will tend to stretch. This is not an issue for anyone who will put their clones right into flower. If you were to produce other models you may want to include some blue LEDs which operate on a switch to make the light suited for both vegetative and flowering as the blue lights will discourage plant stretch and decrease internodal spacing.

I spoke with Alva about producing some all white LED panels and asked her to email me a quote for them. She said you would be using epistar chips and I also wanted to know the model number so that I could check to see the quality of their color myself before I made any recommendations. I can check it with a color temperature reader. She said she was waiting for the Engineer to get back but I have not received an email.
I find your 300w 3 watt chip light panel a suitable carcass for my design which could only be improved if the panel were square in shape but that criteria is subjective to the growing space.

I am not an electrical engineer but I am a chemical engineer. I am not completely knowledgeable on LED lighting and I'm unsure if you wire your LEDs in series or in parallel. I feel that the highest quality LED which can be provided is made by Cree.

If they are to be wired in parallel the ordering number for the Cree LEDs is: MLCAWT-A1-0000-0000E5

If they are to be wired in series the order number for the Cree LEDs is: MLCSWT-A1-0000-0000E5

Cree produces very high quality LEDs which have been shown to provide superior results for growing plants
...
Anna said with an order of 200 units she could produce them but with the higher quality leds the price would be steeper. She would have to source the leds and speak with her plant manager to determine a price. Is this something you all would be interested in and should I start a new thread asking who would to commit to buying how many? Once there was a commitment for 200 their usual turn around time would be about a month. Just trying to get you all a good deal before someone patents it and rips you off.

two mars II 400w would be better

Hey Sara, you have me utterly confused now lol. In your email you told me that the reflector 96x3w was the best choice for the space. So you can see my dilemma.

Does anyone have pictures of a grow with the mars 2 44w? Also the 96x3w reflector?

I am sure it would help other people make an educated buying decision too!

 

[robert63]

Your tent is only 5' tall, reflector model might be a better choice. You might want a little more height for the Mars2 depending on how tall you grow your plants.

Let me explain why the price increased since this month.

Actually, the price increase in Europe and Australia. US has a bit lower price. the cost in United States is lower. compare with duties we paid and warehouse rent fee and other cost. In united states, we mark " led light" then we pay duties for that product. in UK, we mark " led light" we pay duties and other fees according to hydroponic led grow light, your customs checked us, and they said our product is hydroponic led grow light. after we pay a lot VAT and other cost. we got a bill from UK last month. 20K pound. I forgot my boss told me what that cost is, it seems it is another duties or taxes or something, we need to pay each season. OMG. too much we need to pay if we stock in UK. but we have to stock there for customers convenience . so now we are trying to stock in Spain but not UK. if we success in Spain in October,. and they do not charge us extra duties or taxes or other charges we do not know. then we will stock in Spain but not UK,. it will depends, we are negotiating with agent now.

I am sorry my friends, we also want to keep the price as low as possible, but we also need to make some money, I believe you can understand.

Thankyou sara.... I must have missed that post... As always your answers are detailed and clear.

As usual HMRC, have done it again.... Massive V.A.T bill...

Seriously, our taxes are a rip off in the uk.... Little buisnesses get clobbered and the multi-nationals pay next to nothing..

I hope spain is more accomodating for you....

Thanks again for your assistance

I just put in my grow cabinet a 96x3 toplight its only been in there for about 4 days but I have seen improvement in the growth and I think I will be switching to flowering early next week (Now the fun begins) you can see the light in my Journal,link below.

Thanks. I do agree that the coverage for the shape the reflector seems to be better. However, the umol of the mars 2 I saw tested on youtube was double that of the reflector, the reflector was actually very low. So I am leaning towards the Mars 2, even with some height issues.

Does anyone have any pictures of an entire grow with a Mars 2 400w?

Thanks Sara, I understand

Thanks fror the detailed explaination. This is a pretty serious predicament... so many fees.. I hope your company will find a good solution that satisfies most of the people.

I have both going right now...... It is in the journal in my signature .......

U talked with Sara? haha, I am her assistant please take recommendation from Sara.I am new to led.

Check Dennise's grow, I think he has or he can take photoes for you. he is very friendly

 

[lexblaze]

I have also grown in Mars II 400w led check out the journals in growing and completed section Im sure you will find if you search

 

[Mars Hydro]

yes, we are trying our best to find another warehouse in Europe, hope we can find the right one ASAP.

Wait.
I just realized something. You were only explaining why shipping costs increased (which was well explained).
But my main problem with the shipping is, that you add +75$ (EU) for each piece on your website.

So 2 pieces is 2x75$ = 150$ shiping.
10 pieces is 10x75$ = 750$ shipping!!

I see no logical reason why you are doing this. Your explaination tells us why you have troubles etablishing a warehouse (taxes & other) in EU, but the EU can't charge you taxes if you simply send one big parcel from china.
I dont mind waiting 30 days if it can save me hundreds of dollars.


And I will not accept a system where my only option is to pay +75$ for each piece, no matter what the explaination is.

You could charge +xx$ extra when I select "UK warehouse", but not when you send from china.

Pack for example 10 pieces in one big parcel and charge 75$ + 25$ for the increased weight = 100$, that is ok, but not 750$!!!

I hope you see now what my point is.

cheers!

We ship from China, yes, you can save some on shipping cost, but you need to pay duties and service fee. express company will charge you . it is also the same as we ship from UK. we ship from UK, customs will not check you. if we ship from China, customs will check your information. you have record at your customs. do you want it? we are taking dangerous to stock in UK, if you prefer us to ship from China, we can cancel stock in UK. but from our experience, we get more troubles if we ship from China.
