Plants use more than just red and blue light. You will not have good results with this setup! My recommendation would be for 2x400w hps if you plan on keeping your plants short.. If you want to grow some trees.. you may consider 600W HPS to get better canopy penetration. I use a few 12 band LED's along side my 1000W hps to help with resin production and it does seem to help quite a bit. But you need a full spectrum of light for the plants to respond well... NOT just red and blue!

Hey guys first post here, I wanted your advice on a box I was planning to build very shortly, box is going to double up as a bed/bookcase hopefully when built! So the internal dimensions of the grow room are 7ft x 3ft, thats 1 square foot per plant? For my lighting... here comes the controversy, I plan on using 4 led grow lights to each plant. Thats 40watts of directional red and blue light at the optimum levels, red 660nm and blue 445nm each bulb has 3 red LEDs and 2 blue LEDs. What kind Rating: 5
