RH problem.. need some advice on this one.

[Guest]

Whats good everyone. I have about 1-3weeks left on some strains.. I really wanna take them 20more days but It's started rainning outside so the RH inside went from 35-50 to 60-75 with temps at 70-75. I have alot of air movement inside my Grow tent but Im wondering if they'll be safe from mold or I should start considering cutting them down. The RH has been 60-75 for last 3days and it keeps raining.

How much air flow do you have going in the room? How big is your grow room setup?
You would have to have very nice air flow going and no mold or mildew growth in your growing area.

If you can, I would always keep a dehumidifier on hand for problems like this, but if it drops and goes back up your less likely to get it.
Temps have to be kept warm, 70-75 you can still get it, but the chance is a little less.

75% is pretty high, as long as you have constant air flow in the room and that air flow leaves into a different room bringing in fresh air again you will have a harder chance of getting it, if the air stays in the room you have a much higher chance of getting it.

For the ones that are longer the 20 more days one if you want to be safe you can add a little neem to the plant, don't a dd a lot but add a small amount around them. The ones that are going to be harvested in the next 2 weeks do not add it to them, you will have no other choice but to let them go or get a dehumidifier if you want to be very safe.

Air flow is the key though to not getting it even in high humidity...... fresh air comes in and the old goes out, this does not allow spores to buildup in the air causing PM and bud mold.

hey Stitch I think I have a ~700cfm blowering around in the room a 6in duct,4in duct,some 175cfm ones and the window fans. The plants are in a hydrohut and I have air from outside blowing in 24/7. I checked the weather and its supposed to get back to cold in a couple days. I was just worried because I've got mold on clones before from watering to much and know the stuff can appear fast.

is the 6 in duct one allowing the air to come in and the 4in duct to blow out? Oh ya you can have it in a day or 2 just like that. did not know you grow in a HH.
THey should be fine as long as there is always fresh air goes in and the air does not sit in there for long, constant fresh air and you will be straight. So you should be good.

If the temps go down you risk powdery mildew, if temps go up, mold and bud rot, keep those temps stable till the humidity goes down.
