By far my favorite brand as of right now. I strive to keep everything I have in great shape. This light is fantastic! I've gotten great yields from it even though it's only 240 watts. It still provides an acceptable DLI.
I'm new to this brand and to silica in general. From what I understand, this stuff should harden branches, but I thinkni started too late. I'm sure the next run will have big fat branches.
