i got a 600 watt dimmable so it goES 250 watts 400 watts and 600 watts the electronic ballests are the way to go because you get MORE LIGHT per watt then a standard ballest AND YOU CAN USE BOTH MH AND HPS
plus you can start your plants under 2 TO 4 cfl's then...
IM wondering if you can put a 400 or a 250 watt bulb in a digitial ballast and then use the dimming switch.. the reason im thinking of this is to start plants the first 3 or 4 weeks after they gotten 5 or 6 inches high to save electricity
i use cfl now about...
that bulb cant do both, as well as individial bulbs is my thinking' WHEN i see their picture of the light range it looks impressive, however there no percentage numbers like on the hps and mh bulbs that leads me to thing it a misleading ad DESIGNED TO SELL... there OVER PRICED...
