humidity in veg stage you want arounf 60-70% lights on and when the lights off it will go up naturally
in flowering you want arounf 30-40% so your good for that.
id recommend misting the plants lights on...or investing in a small humidifier i had the low h problems and the humidifier perked me up into the 80s:thumbsup:
id say your temps are fine you want 27-30 celsius max and lights off around 20-22 c
just dont hit the dreaded 35c plus marks:rastasmoke:
hope that helps
