I finally got a few plants in the cabinet. After building, improving, .....and
scrapping several kinds of "easy" '"cheap" gimmicks posted around the net I have ordered a cool tube. Not saying im giving up on a bare 600watt bulb in this cabinet by any means. But it is past time to get some plants into flower and I feel 600 watts behind glass is probably better than 300 watts bare. Its been non stop around with the family here on top of me running 5 pages worth of trials monitoring - charting and trying different ideas.
I made the road trip and purchased a 6 inch 435 cfm exhaust and installed as above but then removed the scrubber as it was too restrictive.
with 600 watts I couldn't get consistent stable temps below 86ish but had a couple designs that held good right there. Problem being is I still have a temperature differential between 9 and 11 degrees between cabinet and room with open door to rest of house during trials.
I am about mid way in the high portion of my variable speed 300 watt.
I've been rock solid for a few hours last night and all day today. at 75.3 with a differential of 2.8 deg. Sweet spot for nice tight nuggets if I remember correctly.
My piddling has led me to believe that vertical may be the answer to or at least a part of my quest for 600 bare bulb watts of fake sunshine.
I didn't neglect the plants any during this although two morning cases of bulb burns due to overnight growth.
But up close picking plants for the cabinet today i see something i don't think is heat stress.
After last watering (plain water - dechlorinated)...... three days ago i believe.
