there are some ballasts out there that will help you save money. Look for the digital ballasts, the start-ups are smoother (no flickering), use less electric, and depending where you get your stuff can be just a touch cheaper. Your still gonna get the lum's as you would from the coil ones, but saving the cash and smoother start-ups are huge plus for me.
whatsthatsmell Reviewed by whatsthatsmell on . How much weed per watt Would you get using say, a 400watt HPS? Soil or hydro matter? I've heard it does and it doesn't. I've heard 0.5 grams per watt per month, also heard 1 gram per watt. Rating: 5
