wouldn't it be better to just do this?

No offense, but you're a little paranoid. Bud rot isn't a very common problem and many growers have at least as high humidity as you do. Some of these strains grow in the freakin rainforest for crying out loud. By the way, dehumidifier + open windows = lost $.

Mother's finest, it's a relief to hear this from you, you do have almost 2000 posts up. And yes, I am paranoid, it's newbie paranoia! I've spent a lot of time on these forums just trying to anticipate anything that can happen. Dunno about the dehumidifer + open window equation though. It does drop my humidity and temperature down early in the mornings.

You should see my room though, when I open it up, there's so much condensation I can't imagine that my buds will enjoy it much. Let me re-phrase my question: instead of living in constant humidity paranoia, can't I just foliar spray and not worry about humidity?

What size dehumidifier and how big is the room?

With the window open, you are pretty much sticking your dehumidifier outside trying to dehumidify the world. Like opening windows with the a/c, heater on

With the windows open, the fresh air from outside would replace the air dried by the dehumidifier. You'd essentially be dehumidfying the outside.

Spraying the plants increases humidity. In high humidity situations, spraying should be avoided.

As long as you have constant fresh air flowing into the grow area and air blowing on the plants, the humidity shouldn't be any problem.

Alright, won't open the window again, I don't want to dehumidify the world, lol. I know spraying increases humidity but I'll spray them after lights out, with a "bud rot" foliar spray. The idea is to prevent budrot. I couldn't care less about humidity as long as my buds don't turn into crap.

Can't you just tell me if using a bud rot foliar spray will prevent me from worrying about humidity? That's my question really.

Don't spray them. Don't worry about humidity at 60% till your at week 5 then start to lower it. I keep my humidity at50% and never have problems. Just keep fresh air circulating in your room. The fresh air I'm talking about isn't from the outside its from your room or adjacent room.

This whole mess started when I came across this post from Asta: "And spraying (bud rot solution) under HPS lights is fine cause you have to do it just after they turn off for 12 and leave the area to sit in comditions that would normally promote mould growth. Ie you limit venting and airflow. It is pretty weird doing that to your girls."

It just lead me to this question: why do people spend so much time, money and energy on trying to keep humidity down when one can easily solve the problem with a bud rot spray? Although I appreciate your input and learnt a few things, I still want to project myself into late flowering and want to say "F.U. humidity. Tired of reading threads about you. Go up to 100%, see if I care, I got this magic spray!" No?

the higher the humidity the longer the stalks will be on your trichomes, this makes them more prone to breaking and falling of after the drying/curing stage.

the lower the humidity the more resin the plant will produce so a low humidity serves more of a purpose than to just prevent "bud rot".

the chances are that if you see condensation on the walls of your grow room that you may encounter such problems. keep the window open during lights on and close it lights out with the dehumidifer on, then again it depends on what size and power your dehumidifer is.

try and keep it low and please don't spray anything on to buds, i really disagree with doing that.
