Im doing a Vertical Grow and I read somewhere that you should veg with a vertical light if you're doing the vertical grow. I dont see why this is necessary. Can someone shed some light on this, whether it's true or not? Thanks
I have noticed that with vert. grows the light usage is maximized by surrounding the bulb with a wall of plants, so to speak. you could do it with a horizontal bulb, but I imagine a vertical placement would be more synchronous with vertical growing.
