Thread: Question about LED lights

i have every thing for gowning weed but i have serious problem with light
i live in Iran.in my country its will be very very very expensive if you want to grow weed under HPS or Halide light so i want to try LED lights
i search in many web sites to get information about growing weed under led light but non of them give me answer to my questions.those sites just advertise there own products.
i have many question please answer me even if someone ask them before.

1.should i use Full spectrum LED necessarily?

2.for each plant how many watt LED lights should i use?

3.how many red and how many blue LED lights should i use?

4.should i increase the lights in seeding to vegetarian to flowering?

5.is it necessary to make grow box?(many people in YouTube use some kind of boxes that cover with aluminum inside)

6.how many grams one plant product usually?

7.what is UFO LED?is that some kind of LED lamp?

please answer me in simple way.i don't know anything about lamps or electronic devise or anything else.

Just buy from the company I bought my LED light from.

Hydroponics Hut. Although they are American... I don't think your country is on good terms with them...

You can see my grows in my signature.

Hope this helps

come on what the hell.did you even read my questions?
of course i cant buy what ever you have when i live Iran.i need answers to my questions.don't tell me buy something that is already ready to use
i want to learn how to make it on my own.

Dear Sir,

UFO's are simply low wattage LED light fixtures made in a round shape. They sort of look like an alien space ship. That's why they are called UFO's. This kind of LED is inexpensive and well suited to very small growing environments. Noise, electrical consumption and heat output are low compared to HID lights. Not zero, but low. However, yield is poor and buds can be fluffy.. Use a veg/clone type of LED for the early vegetative stage of growing and then switch to a flowering type of LED for the finish. Making grow box is easy if you are handy with basic tools. Use mylar to line the inside of the grow box instead of aluminum. Or buy a grow tent such as the ones made by Secret Jardin.

I have a very small grow in a closet that is 2' by 2' square and six feet high. Six feet seems like a lot except that you've got to allow space for the plant containers at the bottom and for hanging the light at the top. Plus the space between the light and the top of the plant So there's really not that much room left for the plants. I use a 90W veg/clone LED for the vegetative stage, about six weeks. As the plants begin to flower then I switch to a 135W flowering LED. These are BlackStar lights.

Yield is about 1/4 ounce per plant on average. It's crap I know. I own HID's and would light 'em up in a heartbeat. My current situation simply doesn't work for that. The led set up gets me by. Low electrical use and low heat are critical for me.

what are the differences between normal led and full spectrum led lights?should i use full spectrum led light or can i use normal led lights?
how many red and blue led lights do you use???i mean do you use more blue or red?

If you check out the Illumitex website you can get a good idea about what spectrum you need for veg and flowering.

Visible light (wavelength 400-700nm), the equivalent of the blue, green, yellow and red, also known as PAR, for photosynthesis.The active area is the most important visible part of the plants use for photosynthesis. Blue and red is the most important part in the PAR spectral band, because the riboflavin in plants can effectively absorb the light of this part, while the green is not easy to be absorbed.
So normal led could be usefull to your plant for seeding,growing and flowering.
Ratio between red and blue depends on your require.Conventional ratio (red:blue) 7:2

Snake，do you have E-mail,Skipe or something like that?
