Here's the biggest tip I can give you, get the biggest grid service the county will allow and have it dropped at your build site beforehand...or buy a 200kw multiquip.
If you have an auto dep and don't fill it with e paps you only put the tip in. I go balls deep
i know definitely want to upgrade the service beforehand. anyways i heard that Phillips might be discontinuing the Epap series light for some ridiculous reason, so might want to stock up now! other companies are already making replacement bulbs and i think gavita will continue to make theres as well though. maybe ask your guy with the hydro store about it, been hearing it from a few industry folks in the bay area.
