So we have not only been dealing with a hot summer, but a very very humid one. This past week in particular has been 92-100% humidity every single day, with not much of a break at night. I have my ladies flowering from 7pm to 7am to help deal with the daytime heat, and I have more than enough exhaust as well as optional intakes (1000cfm total exhausts 500cfm intake) The normal temp range is 72-79 F and the humidity from 49-64%. This week I have been opening my grow room door to RH of 84-91% Once the light comes on (1000w HPS) it acts as a Dehumidifier and the RH drops to 50-54% within 25 minutes. I am worried about the effect that this level of humidity will have on these budding plants (3 weeks in). What do you think? Will the 8 hours of 80% humidity be enough to cause PM or other rot issues? Even with the tremendous amount of air exchange (enough CFM to clear the room every minute!). Please do not suggest a Dehumidifier it is not an option Thanks in advance for your thoughts and positive comments.
