I am ordering the same setup but I am getting the euro light instead gonna 2 6" fans from home depot cheaper than htg and use change over couplings 6" to 4" because the tent comes with 2 4" couplers right? that cool tube is totally inclosed right? your not getting any freash air to the room that way can you leave the reflector but take the glass off? I will have One fresh line coming in blowingthe light and another sucking it off the light to vent to my charcol filter for smell. Great setup plants will do better when you get more lighting. How was the shipping from htg did it say htg on the package?
