I'm definitely not an expert, but just from reading Sticky's and what not... I'm pretty sure that 100 degree temps will cause problems at any stage of growth. CO2 is usually implemented when temperatures go over 95F to prevent growth retardation if I'm "learning" correctly. :jointsmile: The only other advice I can attempt to give, is do what you can for now... and when it's time for 12/12... run the lights at night, keeping temps as cool as possible during the day. Either way, just wanted to get the info ball rolling. Hopefully someone more seasoned will come along shortly.
Stay and Keep :jointsmile:
