This being my 1st grow in years has been a sort of trial and error and can only learn through rookie mistakes,,,The 5 1/2 x 5 1/2 x 6 1\2 grow tent and the 1000 watter with only a reflective hood has done the trick for me for this grow,,,but you guys are right,,the next time I put the plants in for flowering (which should be in the next 3 weeks) I will go and get a 1000 watter with the enclosed hood,,,like you guys say,,it should keep the temp down inside the tent,,I'm also opening up the window at night when the light cycle comes on 12/12 and the cold winter air is blown in with a 12 inch fan into the tent and with the heat of the lamp it keeps the tent at roughly 82 degrees,,works well so far but I will get an enclosed light for the next time,,,thanks for the input,,
