Welcome to the site

Looks very nice so far :thumbsup:

I'd say keep the HPS, it's really not a lot of power. Unless your kilowatt per hour pricing is really high, it probably won't make much of an impact. Mine (400w + fans) costs about 12â?¬ per month during flowering (at 0.067 â?¬ per kwh), but then again I'm on a different continent. You should be able to find your kwh rate from the company or maybe your bill.

I'll be watching this.... Happy growing :jointsmile:
