Hey everyone,
I couldnt find a topic discussing what i wanted so here goes, i want to make my own LED grow light.
And i want to tailor it to vegetative growth, i can always make a full flowering light later, and i will try to find the following wavelengths:
Violet/blue: 410-435
Blue: 445-455
Red: 630-650
Red: 655-670
Orange: ~485
And maybe a few white leds to supplement the above, since it is not known whether there are specific wavelengths that are used for certain biochemical proceses.
I'm still unsure of which kind of leds to use, its one of the following:
5mm, 1w or 3w
I want the total to be less them 50 watt, since it will also be a test for the plants.
The 5mm leds:
Pros: are cheap and a lot (and i mean a freaking lot) of wavelengths are available, there cheap, no cooling needed
Cons: Not a high light output, so has to be placed close to the plants.
The 1w leds:
Pros: dont get as hot as 3w leds, so only a heatsink needed, higher light output.
Cons: do need a heatsink, less options available wavelength wise.
The 3w leds:
Pros: high light output
Cons: not really cheap, a lot of heat, so a big heatsink needed (maybe even a fan), limited wavelengths.
So, from my point of view, the 5mm leds are the best option, but the downside is they have to be placed close to the plant, i was planning on 3 inch.
For the ratio i was thinking: 1 white, 1 orange, 4 blue and 4 red.
Now, i might miss some stuff, and could only find info on led growlight by ppl that grow the stuff my country if famous for, and therefor geared towards flowering.
What would you choose, and why?
And did i miss anything?
