I belive last year my seed starting lighting didn't have enough wattage so I was excited by the opportunity to get some additional lighting. Apparently the operation at this house was very large. Some of what I got wouldn't work very well for my needs. For example, the 1000 watt HPS light bulb is very cool but would be a little bit of overkill for six pumpkin seedlings. My wife would certainly kill me when she saw the electric bill.
