Heres some pics from my last harvest but the set up is pretty much the same. 4 - 4 ft tube lights, blue, red, and soft white set up vertically on opposite sides. One 18in purple plant light and 2 hard white cfls on top. Heres one of some bag seed a few weeks into flowering.
Seven Four - 4 ft tube lights, blue red hard and soft white. An 18 inch purple "plant light" and two CFL's on the top canopy. Ones 20 something and the others 40 something watts I believe.
Sorry if this is a dumb question.. but is that just regular tinfoil you're using? or some fancy stuff I don't even know about?
Actually its Mylar sheets I bought from the craft store. Its a lot more reflective than tinfoil and paint. And is said to be the best there is.
