OK here is my idea for a lid rather than a standerd canopy if you are like me and my brother you eventually move on into plants and things like that and need the top to be open for some of the plants to bloom and lights hung from the ceiling s a little darastic for some of us so rather than doing all that work to hang lights make a lid that is like a box top with a open back and a feeding door on the top and then when you progress to blooming plants you can mount the lid on the wall as a shelf with lights on the bottom hopefully this sparks some more ideas if this doesent make any sence to you guys then i will draw some pictures up for you.
