whoa, i never even thought about having a back up generator to keep the plants running on, what would be some prominent things to look for in a generator to keep as a back-up for just such an emergency? Brands, features, ect... i want to invest in one now. If my power went out for days on end and my plants died i would be so pissed....the worst i've encountered is a day and a half w/o power but i only had 2 plants at the time and both of them survived and prospered well
