I use the Hortilux Super HPS Eye bulb that has still the high values of Red light it normally would but with the added levels of blue. I like the results and spent 70 bucks or so for the bulb (400w) and that company states to replace every 18 months of use and I use a light meter to test. I use a cheapo MH for veg and haven't tried a high buck version of mh but if the lumens are still good then it can't hurt. If anyone has a strain that they have grown out a few times and then changed to the more pricey light bulbs and made a log or just showed pics of the results I would dig that.... and yeah side lighting rules and you can mix the bulbs if your too worried about adding to stretch or limiting it. Either way nice thread :thumbsup: oh and lose the aluminum and paint the area under the plants white or use mylar it will help without the hot spots that aluminum can make.
