safe growing temperatures

So, its dropping to the low 50's high 40's night and low 60's during the day. The trichomes are somewhat cloudy and few amber. any suggestions? also what are the safe growing temperatures of marijuana (more specifically nirvana blackjack). I will post pictures tomorrow.

you have got nothing to worry about until the temps drop below freezing, my girls have gone through two light frosts and are still doing great.

if it is forcasted to frost at night just cover up your plants with a tarp, blanket, or painters plastic stuff

also water them before it freezes

normally you chop after second frost

thanks a lot! I was getting anxious.
