everything depends on what u r using to grow the cannabis plant.
what type hydro system
" " food
" " grow rm set up. ie. closet, attic, basement.
everything makes an impact on the plant. make sure its getting plenty of air circulation. whats the ph run at in your garden? painting the inside of your grow rm. with flat white paint will make a difference. not much diff. than that mylar and will last a long time. mylar gets brittle and is a pain.
150 watts, thats quite low in the output side of things! do you use anyother lighting? very bennificial!
peace
