Dont mean to hijack this thread, but I'm currently using a 600w HPS Digilux Bulb & Nexgen Digi Balast.
I'm considering swapping out my 600W with: 12 32-watt T8 5000K Full Spectrum Bulbs.
I bought the hood/ballast from Home Depot, then put in the T8 bulbs purchased from my local hydroponic store.
Any thought? I'm focused specifically on flowering.Here's some pics of the lights, and previous grows.
