humidity?

not sure wot its meant 2 be but mine is 45/light on 36/light off is this ok? And if not how do i rise or lower?

Your RH (relative Humidity) should be from 35%-65% anywhere in between this will be fine.
MJ plants can grow in RH less than this but it is not the optimum.
Are you sure you are correct as normally RH will rise during lights off???

If you need to increase RH at any point on the cheap then you can hang a damp towel in the room this will increase a couple of %.

Are you running your fans at night? this could cause the RH to go lower at night than in the day.

what stage r you in veg or flower?

your looking for high in veg 50-60%+ and low in flower 30-40% but ya green will grow in all kinds of humidity but if you research a bit on humidity ur see that the high for veg n low for flower have scientific reason.

as for increasing get a cheap humidifier they work well for me, but lowering is abit harder dehumidifiers r much more expensiv.

you want it right where it is if you are veggin and/or cloning and maybe a lil higher for the plants to retain water for their little roots and lower when flower due to the possibility of mold durin flowering!! either way if your plants are green keep it there and try to keep it from drastically changing!!

yes fan r on at night and in 6weeks flowing so they should fine then?

then you only have bout 2-4 wks to go!! you'll be fine !!
