Hello, good ventilation is if you can to replace air every 5min. You can calculate the required fan capacity in cubic feet per minute (CFM) by multiplying the volume of your grow space (in cubic feet) by the air exchange rate (in minutes) (using the following formula:(L x W x H)/3 = CFM
In your case (2x2x6)/3=8 per minute, so to replace every 5 min you need 96CFM ventilator, or for exchange every 2 and half minute you need 200cfm vent - standard 4" ventilator

Flushing with RO Water (EC 0,0) or tap water (EC 0,8)?Hi.
I think, it's 1,5-2 weeks before they are ready to harvest.
Tell me, if you see something else in the pics. :)
I want to flush them now every 2 days with only water.
I have the opportunity of RO Water (EC 0,0).
Should i use the RO water or normal tap water (EC 0,8)?

What is shelf life of silver thiosulfate ("STS") in practice?I know it is recommended to use within 30days of mixing final solution.
However, what "works" can often be different from the recommendations. Has anyone used an STS solution they made after 2months? 6 months? How did it go?Other. General questions

How crucial is an exhaust fan and a carbon filter?I cant find anything in my country as a kit, but would buying them piece by piece work?
Example something like in the photo connected to an air duct and then to a carbon filter?
Or if the exhaust fan is not crucial? how can i get rid of the smell in a cheaper way?

Am I on a harvest window?Am i on a harvest window?
77 days old autoflower, up to this point is personal taste or still there ways to go?
I majorly see milky and a few ambers trichomes, correct?
Those white pistils are due to the foxtailing, so is not a good metric.

Question regarding humidityCurrently, the humidity in my tent is ~55%. The plants are in the early flowering stage, so I am worried about mold. Does anyone know if the humidity is too high or can provide a solution without an electric dehumidifier?
