Setting up my first grow and having issues with my tent being too cold. My 4×4 tent is in my 62°F basement. I have a 4″ vent fan at the top of the tent and a 4″ intake vent at the bottom. I’ve added a 1,500 watt heater but even with the vent fan NOT running I can’t get my tent over 69°F. Sorry I spent the money on LED lights (Mars 2000) as I could really use the heat from conventional grow lights about now.
Should I completely seal the tent and find a way to add CO2, do I need another heater, or what would you recommend? I’m already about $800 into this new hobby and would really like to get a successful grow before spending much more. Thanks for all your advice, knowledge, and entertainment!
