Zdaravo people,
Im gonna attempt some growing via a DIY Led system.
Ive been reading some threads and its got me going, Just in ma head (makes a change)
My Goal...
Being able to light an area of 1 sq metre growing 4/6 full size plants (I say full size plants, obviously this will be done indoors and covertly, so I reckon on about a 4ft finishing height.
Replicating as close to a 400 w HPS lamp as poss.
I know that I am not trying to replicate the 50 000 lux I get from my Hps,All I gotta do is replicate the specific bands of light usable by the plant,which I fink are as follows
80% red @ 660 nm
10% blue @ 435nm
5% far red @ 740nm
5% uv-b @ 300nm
Ok so far, this gives me percentage.
We can calculate that a 1000 w hps light only delivers 124 watts of energy to the plant (108w direct and 16w indirectly) right. So to estimate the wattage I need:
124 / 10 = 12.4 per 100w, 4 x 12.4 = 49.6 w
So I reckon I need 50 watts of effective lighting from my leds, spread over 1m 2.
right so far?
Power supply to be 12 Vdc.
Just trying to decide what sort of array to make (any ideas?) needs to be on a frame to raise and lower easily,
Obviously all light needs to combine and be spread evenly over the plant surface...mmmmmm.
LEDs Im shopping for now .
Just need to know how many Leds for 1 w of power
