I am on my first grow and I'm using cfl's. I'm building a light wiith a horizontal hanging hood and my this is my question. Does it make a difference on light quality whether I mount the lights hanging horizontal or vertical. Any info is apreciated.
I have an unknown sativa plant 4weeks into flowering and progress seems to have stopped and some of the pistils are dying off. There aren't any pistils showing on the lower 2/3 of the plant. Any ideas?
