What temperature is too hot for vegging and flowering?

Got a question I’m a newbie to growing I germinated seeds now in soil sprouts are present. I am currently NOT using grow light yet should I? And I am using a good heat mat under them ? Right or wrong? Thanks all :grinning:

If you had a good sunny spot by a window would do the trick

I put my seedlings straight under 1000 mph after first week and they are thriveing

Hello I’m growing in a 4Ɨ4 tent with marshydro ts 1000 light I live in a state where humidity stays high I have a dehumidifier and 2 fans and a bowl of rice in my tent my babies are about to be 2 weeks old and they only have the 4 leaves so far.
