Thanks for the heads up Farmer Rich...but the tent that Im getting is heat rated up to 1000 watts. I do have an inline fan and Im buying a cooltube light. The tent is big enough for the 5 gallon pots that I have now. Each pot takes up just a little less then 12 inches. So I sould be able to fit 9 in that tent. Its 6 feet plus im growing in the middle of winter. I can always open the window if I have hard time venting the heat which i doubt. Currently Im using a closet with Six 5 gallon pots...two 3 gallon pots and two 1 gallon pots. The space in there is only 2 feet by 5 feet. I can trim as needed if there is over growth
