Ok so think im gonna just go with the 250w hps, i wouldve completely gotten the 2 ft 4 lamp tek but the grow box were building isnt 24" deep, and we need as much yeild as possible so the Hps is our best bet in my mind. I know temperature will be a major issue with summer coming up, but we checked his attic today and realized that it is fully insulated, so the a/c unit we put in there should keep the ambient temperature of his attic and the temp inside the box at around 75. maybe up to 80 on hot days but well just crank the A/C in that case. The box is gonna intake directly from the A/C unit, and it will exhaust out of his house so i think we got that situation under control! Thanks for the help guys! Ill start a thread as soon as we buy the wood for the grow box. Ill be updating this thread either today or tommorrow with new pics of the setup... I hooked up the new light and she grew about an inch taller overnight which is amazing! temps got up to 88 though, so im hooking up an exhaust fan for the area today.
