That is perfect to go all the way since the bulb covers both light spectrums, if ure starting from seed get the seedlings a foot maybe a 1 1/2 feet away, if ure starting from clone u can go a bit closer, just remember the cooler u can keep the bulb the closer u can put light....the closer the light the better the plants will do...
