Yes, thanksyea def that humidity is low i usually keep my humidity from 60-75% while vegging and 45-60% in flower but the last 2 weeks of flower i usually keep it around 30% humidity...hope that anwered your question
Put a bucket of water in there, it will still grow with the low humidity.I have a Growlab80 which is 2'7"square by 6'tall. I have a 600hps going about a 12" above the plant. I have noticed that the room is low to mid 80's witha humidity of 15-20%. That seems a little low.
