Hyponex potting soil with compost mix as of 2 days ago .have got the temp down to 80 but as stated i dont trust my thetmometer at this time cause it does not feel that hot when my hand is above plants or when im in the room i do think first light cycle i had light to close and had sprayed plants which was dumb i know ! They are certainly growing i know that so i am assuming that is a good sign
