So you saying to go 600wat or gradually build up sorry confused me a bit lol. Not a fan of having heat on through night tho with the choppers about lolHave lights on at night mate especially with the summer coming, yeah 250w and gradually build it up, I've always just slapped my 600w on full n let them do their thing, they stretch just a little but the results are GREAT, i never pull less then 7Oz per plant
