not sure yet ill let you know when I find out lol. Picked up a 42w today! will use a 23w+42w for ~5000 lumens. Store didn't have any good soil, in fact walmart didn't even have above a 23w bulb so I had to go somewhere else. I regret not buying another roll of silver duct tape, that stuff really seems to reflect well. So my plants are currently deadish and I was wondering if I should start from scratch or attempt to revive them. How does fresh dirt compare to potting soil? Gonna go eat some firecrackers, hopefully will have the lights remounted tomorrow.
