Mars-Hydro LED Grow Light Discussion

[unforgiven]

puff the magic dragon!!!

Anyone wants it? What will this little dragon remind you of?

I am leaning more towards the Epistar, does the Cree having a different light pattern due to the curvature of the reflector? I could see how it may make it spread a bit more evenly at the edges.

You like the Epistar design or Cree design?Peronal,i like Mars Pro II Cree desgin,the curved surface.
You can go with Mars Pro II Cree128 or Mars Pro II Epistar160 for a 3'x3' growing space.

I thought babies would like the LED lights as well as the bigger plant.

Sure, assuming the spectrum is "friendly" to seedlings (they might prefer a little more blue, but that's splitting hairs). The issue is the amount of light that they receive. Mature, large cannabis plants can use (depending on strain) up to 1,500 µmol of light. Equatorial sativas might be able to use up to 1,700 - 1,750 µmol. But if I remember correctly, that's assuming a flowering schedule (12 hours of light per day (or thereabouts, again depending on strain). Too much light can actually inhibit photosynthesis to a degree.

Tiny seedlings cannot use anywhere near that amount.

BtW, Jimdog, if you turn that CFL so that it orientated horizontally instead of vertically, you'll get more light to the plants; like most bulbs, they produce the vast majority of their illumination at the sides of the bulb; you might notice a bright spot on the wall (or would if you shut the LED panel down for a moment, lol) closest to the CFL when it is just hanging like that - because that's where the light is going, onto the wall. Also, you can create a simple yet fairly effective reflector for a CFL bulb out of a soda pop (et cetera) can by cutting it so that the side opens up like a pair of wings. Remember to leave enough material at one end so that it'll fit snugly onto either the base of the CFL or the socket and you won't need to work to figure out how to hold it onto the bulb. The other end (the bottom) may be left, too, and simply angled so as to help reflect the (relatively small amount of) light that comes off the top end of the bulb down toward your plants. One or two CFLs, in the correct orientation and with these homemade reflectors, can make adequate seedling lights (either in your tent or, well, just about anywhere since seedlings do not reek of cannabis, lol).

Thanks for all the advice. I've actually tested the Cfls sideways and the light output doesn't change a whole lot because the size of the bulb is so small (24w) the reflector is a great idea. I'm waiting on a few double adapters for the sockets so I will build them into a diy reflector once they come!

Morning Darkscotia,i confirmed with my colleague at shipping department,we have these tent in our container this time,it's already on the way to Canada.It may arrive at Canada around Oct.

Sara any timeline on those tents being sent to Canada looking for 8-4 and 2-4

 

[Mars Hydro]

Does it looks like cannabis oil? I will buy one for you,which pattern you would like to have?

puff the magic dragon!!!

 

[Mars Hydro]

Mars Pro II Epistar is good.Right now we only have this curved design for Mars Pro II Cree,but we will publish new lights at the beginning of next year,it use OSRAM diodes.

My little Dinafem White Widow Auto under Mars II 400w. She's got leaves as big as my hand

Tell Mercy thank you for the help

It's the same for human babies,when they were just born,they can not take too much food or anything,they are fragile.As they grow older,they can handle more stuff gradually.
I think anyone who have good experience of growing cannabis must can take good care of infants.Do you?haha,i think i know how to do with them now...
Mature plants can use around 1500--1700µmol,it is like safe line.I will keep in mind.

TorturedSoul always give us good ideas here.
Looking forward to your results.

Thanks for sharing with us here.
wow,i think her leaves can cover my face.I like her green color,she is flourish
Will you top her again later?

My little Dinafem White Widow Auto under Mars II 400w. She's got leaves as big as my hand

Tell Mercy thank you for the help

Wow what a fiesty looking plant you should trim up some big leaves tho I can see some are covering future bud sites. You'd rather have thoughs bud sites get light then a big old fan leaf

Nice! I'm always thrilled to learn about new technology and new products (even if I can only read about them).

Does your company have any plans to create any products that use high-powered COBs instead of the small monochrome LEDs? They seem to be quite good at growing cannabis (and white light is easier to work under than purple, lol).

I think anyone who have good experience of growing cannabis must can take good care of infants.Do you?

Actually, due to "circumstances beyond my control," I was taking care of babies - feeding / diapering / playing with / caring for / keeping them out of trouble, the whole nine yards... when I was six or seven years old. Mom used to babysit and she got real sick, so sick she couldn't even get up and was half out of her mind. The parents of the little kids kept dropping them off at the house, so someone had to deal with them.

I have cared for children (of all ages ) most of my life. But it got too hard. You get attached to them, and then they leave.

Mature plants can use around 1500--1700µmol,it is like safe line.I will keep in mind.

There still seems to be some debate about those numbers. They might be a little high. And I believe that there is also a relationship with the hours of light that they receive in a day, the temperature (needs to be warm enough for optimum energy production, but not so hot to cause the plants to seal off the stomata in their leaves), the amount of CO₂ in the air, et cetera. But you certainly would not wish to aim for higher light intensity than that, because it would be wasted. That is one of the biggest arguments in favor of having LED panels that are physically larger, methinks - so that one can spread the light out a little instead of concentrating it all in one small area.

Those big leaves really beautiful,but they cover the lights for the small leaves under it.

Sorry guys,i made a mistake.
Due to USA strict custom clearance request,all container need to be checked at US port.So that the container which arrived at USA on Sep 8th need more days at the port.When we finish the custom clearance,we will let you guys know as soon as possible.
Reflector48 is out stock,Mars II 1600 only 4pcs stock left,Mars Pro II Epistar 320 & 2'x2' grow tent are out of stock.
I'm really sorry about the previous notification.
But please do not worry, we have another container which will arrive at Sep 13th.

 

[Mars Hydro]

OSRAM &Philip both want to cooperate with us,but we decided cooperate with OSRAM.They will help us design a new light.I'm looking forward to the new light also.
When i was in high school,every summer and winter vacation i need took care of my nephew. He is cute,but sometimes really annoy.
I understand that,different situation and there are many other factors can affect it.

USA &Australia are moving warehouse these days,they need time to settle down.This may cause delay on arranging shipping,we will try our best to make everything back to normal as soon as possible.We are sorry for the inconvenience.

 

[TorturedSoul]

Is that something new? If so, do you have any idea what prompted the increased vigilance? (Some event somewhere in the world, or just the usual US government paranoia, lol?)

 

[Mars Hydro]

Our lights certified ETL test 3 years ago,but we didn't put it with our lights before.Since last month we put ETL,warranty card &instruction book with our lights together.So they need check our goods strictly to confirm all the information which we provided.
It's good that they check everything strictly,which will make our customer more to use our lights.

[TorturedSoul]

Oh, okay. I thought you meant that there was increased scrutiny all of a sudden at US Customs in general. I was wondering if there was some kind of new global... incident.
