Well, I had another 250w HPS ballast bulb, etc. and decided to put it in the flower and run a test to set how the heat was going to be. Alls well so far, haven't gone over 88. I'll need to move the blower fan and probably set up a thermostat switch for the blower but I pleased so far. 500w 's of HPS in a 20
cu.ft area and only 88 w/ roughly 100 cfm of cpu fans. Now to get another light base ...
