true ill try that i still have like 4 weeks till harvest i cant wait its my first grow ever! i have pics in an album feel free to check it out and comment
uhh like 4" if you have a fan just blow it on the bulb so it keeps it cool. Pretty much the closer the better as long as its not hurting the plant cause you want the plant short and bushy. i have tons of pics in my album feel free to look!
