BUT YOU BUDS ARE HUNGRY FEED THEM OR THEY WILL BE STRESSED FROM MAL-NUTRITON WHICH WILL EFFECT BUD PRODUCTION

i grow in deep water culture....my night time temps are a regular 40 degrees F...i am using an aquarium heater from petco seems to be workin alright havent had no problems yet.....only thing i seem to notice is the hairs are shriveled up instead of growin outwards..

Ultimate indoor night conditions should be NO less then 65...cold temps stunt growth, dropping too cold will almost STOP your plant from growing. Ultimatly not going lower then 5-7 degrees at night from your day temp is best.
