i use dual spec hps,the sunmaster ones,, best i think, anyways,, i always thought u couldnt use a MH bulb on a hps ballast,, i now here thats just a maketing ploy to make u spend more SO from now on im gunna use a 600MH for veg and HPS for flower
i use cfls for kjeeping them in mu clone box u need much more cfls than that buddy for that amount of plants,,smaller pots would have been easier to regulate the feeding
JIMMY u use one of those filter damn i bet u get sum hi water bills buddy,, we just got a gps watermeter fitted had no choice, they dont even need to come out to get my meter readings now just satelite shit,, just another example of big brother watching u,,wouldnt suprise me if they put mics in em to be fucking nosey,the cunts
