use these wavelengths for the best absorption coefficients...View attachment 1903192
Up and coming 50 watt red 630nm for flower. I made the mistake of ordering the wrong LED driver. But It did work momentarily and this SOB is so bright that you wouldn't be able to look at it across the street at 12 noon. 2000 lums, Perfect for pc grow.
2000 lums may not seem that bright compared to HPS or MH. but consider this, 2000lums coming from the area about the size of a dime.
for reds youre only going to want to use a higher wavelength targeted only at 640 or 660 nm for red... otherwise you're gonna miss the highest peaks on the spectral curve to get the most out of the peak chlorophylls b at 640 and chlorophyll a at 660...
For the blues it looks like you have picked a good wavelength of 455-460...
so if you can get a combined effort 4 wide spectrum 40 watt cfl's 2 2700k and then 2 6500k for the blend also those cfl's tend to have a broad spectrum of light in them and arent just "red" or "blue", then add in there 4 50 watt red led's that are intense enough to cover a 2x2 area with an even lux all around, and 4 50 watt blues of the same area then you should do just fine for about 4 plants in that area you have now, or about 200 watts for per plant
if youre going to keep the plant small however, and you dont really care about getting more than a 10 "dimes" out of a plant then keep it the way it is...
But... by adding a glossy EVEN white reflective surface beneath and all around you will highly increase the effectiveness of the little room and little light that you have available and you will definitely increase your yield... tremendously... all of that metallic reflective surface is bent and curved and is, as of what the picture looks like, is pretty much useless to you and your plant, other than creating hot spots on your plants and doing really nothing to increase reflectivity to your plant as a whole...
i only say these things to help so please dont take it as me being an ass lol
also be sure to check the diameter of the focal point of lux for your led's to make sure that its intensity is spread out on an even parabolic curve, otherwise you may only be giving an area of a dime on your plant the intensity needed for good growth
