can i dry my plants in the bathroom

im planing to dry my plants in the bathroom,will the occasional lights on effect them much and should i leave the fan on all the time

It's fine.
Fan on, yes.

fans on all the time,90m3/h and the bathroom 14m3 is that ok.i really neeed this advice couse the last bash i dryed in a box whit two holes on each side and now that its dry my weed smells bad,even worse than that its like dry grass from the lawn,is that smell becouse i didnt have a ventilator or can it be something beside that.the temp was 68-70 f and the humidity 45-70

Maybe a carbon filter? It wouldn't hurt- But it sure ups your budget a little, if your drying and in a bathroom remember warm showers can give off a lot of humidity which may play around with your drying process as well. Good luck

Hope this helps

If you plan on drying in the bathroom, I would recommend monitoring closely the humidity of the room. You do not want to have humidity levels more than 55% for it can delay the drying process and also invite mold and mildew.

right now one hum.meter tells me its 50 and a nother tells me it 70 so i dont know if im gona have to get third one to settle it,if its 70 should i get a more powerful fan
