Thanks, the ducting is ok as there is another light to the left of it. Just got through re-arranging the plants as I have 1 un-vented hood to provide heat so i have to keep the tops a little further away from it. The vented hood has tops within 15in. My big issue has been dealing with this crazy weather in NorCal the last few weeks the 63 deg days are fine but the 27deg nights up here on the hill are killing me. I have been running a heater at night just to keep the temp from falling below 55. And now the mites show up, can only hit them with some Safer and rosemary spay at this point. 14 more days and it should be done.
